DC Power Relays that Interrupt High-capacity
DC Loads and High-voltage DC Circuits
in a Compact, Low-noise Design
In the endeavors to prevent global warming, air pollution, and the depletion of oil
resources, much attention is being given to increasing the efficiency of AC-to-DC
power conversion and distributed power generation. DC contactors and circuitbreakers, however, are disadvantaged by their noise and bulk.
OMRON has improved on the standard DC circuit that switches using a contactor or
circuit-breaker by developing the G9EA/G9EB/G9EC DC Power Relay Series. These
Relays enable switching high-voltage and high-capacity loads. The switch's gas-filled
construction allows a considerable reduction in the relay switch size, while also
lowering the operating noise during load switching. Furthermore, the new design has
decreased the power consumption of the coil and achieved long-term contact
stability.

DC Power Relays (200-A Models)
G9EC-1
DC Power Relays Capable of Interrupting
High-voltage, High-current Loads
• A compact relay (98 x 44 x 86.7 mm (L x W x H)) capable of
switching 400-V 200-A DC loads. (Capable of interrupting
1,000 A at 400 VDC max.)
• The switching section and driving section are gas-injected and
hermetically sealed, allowing these compact relays to interrupt
high-capacity loads. The sealed construction also requires no
arc space, saves space, and helps ensure safe applications.
• Downsizing and optimum design allow no restrictions on the
mounting direction.
• Terminal Cover is also available for industrial applications.
• UL/CSA standard UL508 approved.
Note: Refer to Precautions on page 22.

DC Power Relays Capable of Interrupting
High-voltage, High-current DC Load
• Utilizes a unique gas-filled, fully sealed, non-ceramic construction achieved by using resin with a metal case. This reduces the
need for special processing and materials that were required
with previous models, resulting in a low-cost relay that is both
compact and lightweight.
• Smallest and lightest in its class at 25 × 60 × 58 mm and approximately 135 g. This is approximately half the volume and a third
of the weight of other DC Power Relays in the same class (400
VDC, 25 A).*
• The unique design of the contact switching component and permanent magnet for blowing out the arc eliminates the need for
polarity in the main circuit (contact terminal). This improves
ease of wiring and installation, and contributes to providing failsafe measures against incorrect wiring.
* Based on our investigation as of December 2004.

The above values are initial values at an ambient temperature of 23°C unless otherwise specified.
The contact resistance was measured with 1 A at 5 VDC using the voltage drop method.
The insulation resistance was measured with a 500-VDC megohmmeter.
The impulse withstand voltage was measured with a JEC-212 (1981) standard impulse voltage waveform (1.2 × 50 µs).
The mechanical endurance was measured at a switching frequency of 3,600 operations/hr.
The electrical endurance was measured at a switching frequency of 60 operations/hr.
These values are for when a varistor is used as the protective circuit against reverse surge in the relay coil. Using a diode will reduce the
switching characteristics.

Precautions
WARNING
Take measures to prevent contact with charged parts
when using the Relay for high voltages.
■ Precautions for Correct Use
Refer to the relevant catalog for common precautions.
1. Be sure to tighten all screws to the appropriate torque given
below. Loose screws may result in burning due to abnormal heat
generation during energization.
• M8 screws: 8.82 to 9.80 N·m
• M6 screws: 3.92 to 4.90 N·m
• M5 screws: 1.57 to 2.35 N·m
• M4 screws: 0.98 to 1.37 N·m
• M3.5 screws: 0.75 to 1.18 N·m
2. The G9EA and G9EC Relays’ contacts have polarity. Be sure to
perform connections with the correct polarity. If the contacts are
connected with the reverse polarity, the switching characteristics
specified in this document cannot be assured.
3. Do not drop or disassemble this Relay. Not only may the Relay fail
to meet the performance specifications, it may also result in damage, electric shock, or burning.
4. Do not use these Relays in strong magnetic fields of 800 A/m or
higher (e.g., near transformers or magnets). The arc discharge
that occurs during switching may be bent by the magnetic field,
resulting in flashover or insulation faults.
5. This Relay is a device for switching high DC voltages. If it is used
for voltages exceeding the specified range, it may not be possible
to interrupt the load and burning may result. In order to prevent
fire spreading, use a configuration in which the current load can
be interrupted in the event of emergencies.
In order to ensure safety of the system, replace the Relay on a
regular basis.
6. If the Relay is used for no-load switching, the contact resistance
may increase and so confirm correct operation under the actual
operating conditions.
7. These Relays contain pressurized gas. Even in applications with
low switching frequencies, the ambient temperature and heat
caused by arc discharge in the contacts may allow permeation of
the sealed gas, resulting in arc interruption failure.
In order to ensure safety of the system, replace Relays on a regular basis.
8. Do not use or store the Relay in a vacuum. Doing so will accelerate deterioration of the sealing.
9. With this Relay, if the rated voltage (or current) is continuously
applied to the coil and contacts, and then turned OFF and immediately ON again, the coil temperature, and consequently the coil
resistance, will be higher than usual. This means that the must
operate voltage will also be higher than usual, exceeding the
rated value (“hot start”). In this case, take the appropriate countermeasures, such as reducing the load current or restricting the
energizing time or ambient operating temperature.
10.The ripple percentage for DC relays can cause fluctuations in the
must-operate voltage or humming. For this reason, reduce the ripple percentage in full-wave rectified power supply circuits by adding a smoothing capacitor. Ensure that the ripple percentage is
less than 5%.
11.Ensure that a voltage exceeding the specified maximum voltage
is not continuously applied to the coil. Abnormal heating in the coil
may shorten the lifetime of the insulation coating.
12.Do not use the Relay at a switching voltage or current greater
than the specified maximum values. Doing so may result in arc
discharge interruption failure or burning due to abnormal heating
in the contacts.

13.The contact ratings are for resistive loads. The electrical endurance with inductive loads is inferior to that of resistive loads. Confirm correct operation under the actual operating conditions.
14.Do not use the Relay in locations where water, solvents, chemicals, or oil may come in contact with the case or terminals. Doing
so may result in deterioration of the case resin or abnormal heating due to corrosion or contamination of the terminals. Also, if
electrolyte adheres to the output terminals, electrolysis may occur
between the output terminals, resulting in corrosion of the terminals or wiring disconnections.
15.Be sure to turn OFF the power and confirm that there is no residual voltage before replacing the Relay or performing wiring.
16.The distance between crimp terminals or other conductive parts
will be reduced and insulation properties will be lowered if wires
are laid in the same direction from the contact terminals. Use
insulating coverings, do not wire in the same direction, and take
other measures as required to maintain insulation properties.
17.Use either a varistor, or a diode plus Zener diode as a protective
circuit against reverse surge in the relay coil. Using a diode alone
will reduce the switching characteristics.
18.Be sure to use the screws provided with the product for wiring coil
terminals and contact terminals. The specified tightening torque
cannot be achieved with different screws and may result in abnormal heat generation when energized.
