Its interrupting capacity reaches 242 kA at 240 V AC and holds 187 kA at 415 V and 440 V, then drops to 121 kA at 500 V and 3 kA at 690 V — so the voltage class of your system determines the fault-clearing headroom.
Integrated undervoltage release and communication
It also carries a communication function onboard, which means it can report status or accept remote trip commands over the SENTRON communication bus without an add-on module.
The 4-pole format means it occupies four module widths in a standard distribution board.
