Product details

Breaking capacity is the headline number for an MCCB: this unit delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. The electronic trip unit is an ETU550. N-conductor protection is adjustable from OFF to 20 % up to 160 %.

That matters for thermal management inside a dense panel — adjacent devices and wire bending space need to account for the heat this breaker dumps into the enclosure.

The breaker includes a communication function for status and trip event reporting.
