It combines thermal-magnetic and electronic trip technologies, with a magnetic tripping threshold of 119 A for fast short-circuit clearing. Breaking capacity reaches 100 kA Icu at 220–240 V AC under IEC 60947-2, and 65 kA at 240 V under UL 60947, so it handles high available fault currents typical of large distribution panels. The device is rated for AC-3 motor switching (IEC 60947-4-1) and supports motor power up to 7.5 kW at 660–690 V AC.
Compliance & Mounting
Certified to CSA C22.2 No 60947-4-1, UL 60947-4-1, EN/IEC 60947-4-1, and EN/IEC 60947-2. The device is isolation-capable per IEC 60947-1 and features a rotary handle control type. Dimensions are 6.5 in depth, 3.2 in width, 6.1 in height; mounting pitch is 27 mm without spreaders, 35 mm with spreaders. Terminals accept lugs or ring terminals with tightening torque of 79.7 lbf·in (9 N·m) for the main circuit. Degree of protection is IP40 (enclosure) and IK07 (impact resistance).
