The interrupting rating hits 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V, tapering to 11.9 kA at 500 V and 690 V — figures that govern SCCR coordination in the downstream panel.
That matters for a crowded enclosure where internal temperature rise is a given — the 70 mm depth and 101.6 mm width fit a standard MCCB footprint, and the IP40 front means it's protected against solid objects over 1 mm but not sealed against moisture.
Specs Summary
Insulation voltage rated at 800 V. Maximum power loss 25 W. No trip indicator, no voltage trigger, no communication function. The overcurrent release design is TM210. For DC switching applications, the manufacturer directs to the 3VA molded case circuit breaker device manual.
