VAL-SQ SI… 36 to 120 kA Surge Protective Device for small installation protection TRABTECH Data Sheet 2789_en_F 1 © PHOENIX CONTACT 2011-04-29 Description The VAL-SQ SI… Surge Protective Device (SPD) provides surge protection in a compact, affordable package. A high-energy suppression circuit provides 36 to 120 kA (depending upon the model) of surge current rating per phase. Each surge suppression mode in the VAL-SQ SI… is individually fused for safety. The VAL-SQ SI… SPD uses a sealed, NEMA 4X housing, allowing installation in harsh environments with limited space. Operating status lights are easily observed and provide verification of protection. – The VAL-SQ SI 36-2C-120 provides compact protection of 120 V applications with bonded neutral and ground. – The VAL-SQ SI 40-3C-600 is for three-phase Wye applications up to 600 V with bonded neutral and ground. – The VAL-SQ SI 40-3-600D is for three-phase Delta applications up to 600 V. – The VAL-SQ SI… 120/240S SPDs are for single- and split-phase 120/240 applications with common or separate neutral and ground. 2 – – – – – – Features Compact design for flexible mounting locations 36 to 120 kA surge current capacity per phase (L-N and N-G) protects against high-energy lightning strikes and transient voltages UL nominal surge discharge current (In) rating of 10 kA NEMA 4X enclosure LEDs provide continuous feedback on the status of each phase UL/cUL listed; meets UL 1449 3rd edition DANGER: HAZARD OF ELECTRIC SHOCK OR ARC FLASH Confirm the SPD voltage rating on the module or nameplate label is the same as the operating voltage.

DANGER: Turn off all power supplying this equipment before working on or inside equipment. Always follow federal and local regulations during installation. Apply appropriate personal protective equipment (PPE) and follow electrical work practices. Only qualified electrical personnel may install and service this equipment. Mounting and connection Position the VAL-SQ SI… so the LEDs are visible and the wires are as short and straight as possible. The SPD can be mounted in any orientation. It attaches through any side of the enclosure being protected using 1/2-NPT threaded nipple. NOTE: Cover or remove components inside any enclosure before drilling to prevent shavings from causing short-circuits across terminals and races. Never open SPD. No serviceable parts are inside. WARNING: This equipment depends upon an effective ground. Failure to obtain a quality ground connection may result in explosion or arc flash. NOTE: Megger® or hi-potential tests will damage this surge protective device. Turn off all power supplying the equipment and isolate the surge protective device before testing. NOTE: Variant 2800007: Suitable for use on a circuit capable of delivering not more than 200,000 rms symmetrical Amperes. All variants except the 2800007: Suitable for use on a circuit capable of delivering not more than 25,000 rms symmetrical Amperes. 2789_en_F PHOENIX CONTACT 4 VAL-SQ SI… 2.

Disconnects to the SPD are recommended. All wires must be connected to properly installed circuit breakers sized according to the wire gauge. Use an appropriate breaker, i.e., 2- or 3-pole, for the electrical configuration. 7 Operation LEDs indicate the operating status of the individual phases of the VAL-SQ SI… The LEDs illuminate when the relevant phase is operating correctly. Device Phase Phase LED LEDs LEDs All wires must be connected for the SPD to function correctly. The wires between the SPD and protected device should be twisted 1/2 turn every 12 in. (300 mm). Do not loop or coil wire. Excess wire must be removed without applying stress to wires.
