Product Details:

ABB System Pro M compact 3-Pole Supplementary protector limits current and features two different tripping mechanisms like the delayed thermal tripping mechanism for overload protection and the electro mechanic tripping mechanism for short circuit protection. It measures 52.5 mm x 69 mm x 88 mm. It has an ambient operating temperature of -25 to 55 deg C and can be stored at a temperature of -40 to 70 deg C. It withstands two shocks for 13 milli-seconds. Supplementary Protector has 90% - 96% efficiency for 28 cycles at 55 deg C and 95% - 100% efficiency for 28 cycles at 25 deg C. It is rated at 30 Amps, 400 VAC. It has a power loss of 9.45-Watts and a power loss of 3.15 Watts per pole. It has a phase-to-phase insulation voltage rating of 500 Volts and an operational voltage rating of 12 VDC/VAC - 440 VAC/125 VDC. It operates at a frequency of 50/60 Hz.

Supplementary Protector has a short circuit current rating of 6 kilo-Amps, ultimate short circuit breaking rating of 10 kilo-Amps and a service short circuit breaking rating of 7.5 kilo-Amps. It has 2 deg pollution. Impulse withstand voltage rating is 4 kilo-Volts, 6.2 kilo-Volts at sea level and 5 kilo-Volts at 2000 m. It can withstand a dielectric test voltage of 2 kilo-Volts at 50/60 Hz for one minute. It features insulation group I, RAL 7035 housing and insulation group II, black, sealable actuator that has I/O marking. Supplementary Protector has ON/OFF circuit breaker indicator. It has a tightening torque of 25 Inch-lb. It can be mounted onto DIN rail TH35-7.5 that measures 35 mm x 7.5 mm and onto DIN rail TH35-15 that measures 35 mm x 15 mm.

Supplementary Protector can accommodate a bush bar of size 18-8 AWG, rigid/standard conductor of size 18-4 AWG and flexible/flexible with ferrule conductor of size 0.75 - 16 sq.mm. It comes in overvoltage category III and is compatible with Pozidriv 2 screwdriver. It features an electrical endurance of 20000 AC cycles and a mechanical endurance of 20000 cycles. It has a magnetic trip range of 240- 360 Amps and a thermal trip range of 31.5 Amps. It has type K tripping characteristic. It has UL/CSA certified maximum operating voltage rating of 480Y/277 VAC. It is IP20/IP40 rated. Supplementary Protector meets IEC/EN/UL/CSA/RoHS standards.
