It's a 3-pole unit designed to sit in a distribution panel or switchboard, protecting downstream cables and equipment from overloads and short circuits.
This MCCB's interrupting rating drops as system voltage rises: 242 kA at 240 V, 187 kA at both 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. For standard 400 V class panels, 187 kA covers most utility-fault scenarios.
The IP40 front protection means it's fine for indoor switchgear but not washdown areas. No undervoltage release or shunt trip is built in (no voltage trigger), so external accessories are needed for remote trip functions.
Thermal performance and trip unit
That's unusual for a thermal-magnetic breaker; the electronic trip compensates for temperature, so you don't lose capacity in a crowded enclosure. Power loss is 4 W maximum, negligible for panel heat budgeting.
