Its adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so you set the pickup to match the downstream load rather than swapping the breaker. The interrupting ratings climb to 187 kA at 240 V and hold 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V — that SCCR headroom covers most industrial distribution panels without a current-limiting fuse upstream. This is a line-protection design with an undervoltage release and a built-in communication function for remote monitoring or trip indication.
Thermal performance and power loss
Maximum power loss is 12.5 W at rated current — modest enough that ventilation slots in a standard IP54 enclosure handle the heat without forced air.
