Altech MA40U Three phase adjustable trip miniature circuit breakers/ manual motor controller Datasheet

Altech UL508
MA- Series
Three Phase Adjustable Trip
Miniature Circuit Breakers/
Manual Motor Controllers
The MA was designed to handle the high
inrush loads of 3 phase transformers,
power supplies, motors, etc. The MA
protects wiring and equipment from
damage caused by the three major
classes of over-current, yet greatly reduces the number of nuisance trips in high
starting and inrush current circuits.
An IEC device with excellent ratings under
a UL listing at 480Y/277V (including group
ratings) and at 500V under international
standards, the Altech/ABL Sursum MA
provides short and long term cost effective
circuit protection for USA and/or export
applications. The short term advantages
include: (1) adjustable thermal trip allows
finalization of initial designs before
procurement of the load equipment is
complete; (2) snap-on mounting for readily
available, internationally standardized DIN
Rail saves panel layout design time as well
as installation and change labor; (3) large
cage-clamp terminals with screws suitable
to power screwdrivers, simplifies and
speeds wiring; (4) convenient switched
disconnect during factory testing and/or
initial start-up saves time and aggravation.
The key long term advantage is customer
satisfaction and proven over-current protection of wiring and equipment (and the
lack of rework/repair costs).

Note: HEA - Horsepower Equivalent Amperes, the nominal amperage assigned to standard motor horsepower ratings in design guide tables such as
NFPA-70 Tables 430-248, 430-249, 430-250; UL1077 Table 16.2; CSA - C22.2 No. 235-M89 Tables 44 and 45; CSA-C22.2 No. 14-M91 Table 19, etc. Multiply
HEA values (in parenthesis) by 1.1 if power factor is 90%, and by 1.2 if power factor is 80%.
a The standard-circuit short-circuit rating is 14kA for all types. Group ratings can be used in a standard circuit (e.g., MA1.0U at 42kA), but a higher
standard rating cannot be used in a group circuit (e.g., MA40U at 14kA only in standard circuit.)

Accessories
Accessories can be factory or field mounted on V-EA and MA manual motor controllers for enhanced
control and monitoring capabilities. Field mounting kits include all necessary parts and instructions.
Accessories can be gang mounted on a single controller (the Auxiliary Switch in the outside position).
The mounting arrangement links the internal latch-pins for the tripping mechanisms, ensuring simultaneous trips. Handles are linked to simplify manual resetting.
