It carries a continuous current of 32 A at 40 °C and delivers a 187 kA interrupting capacity at 240 V — that's the rating you rely on for fault clearance on a 240 V feeder, not a number to derate from. The 800 V rated insulation voltage confirms it's built for 480 V or 600 V class panels as well, with the interrupting curve dropping to 121 kA at 415 V and 75.6 kA at 440 V.
Ratings and so-what
That's a thermal curve you can size a feeder against without guessing. No undervoltage release is fitted, so a control-voltage loss will not automatically open the breaker — that is by design for this variant. It is a straightforward line-protection MCCB with the interrupting muscle for high-fault installations.
Integration and approvals
Maximum power loss is 10.6 W — factor that into your panel thermal budget. The insulation voltage rating of 800 V means it meets IEC 60947-2 requirements for use in 480/277 V and 600/347 V systems. No communication function, so no fieldbus wiring needed — this is a pure power distribution device.
