Its breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so it handles high-fault-current scenarios at the lower voltages typical of North American and European distribution, while the 690 V figure confirms it can interrupt a fault on a 690 V line, though with reduced capacity. The part carries a shunt trip release (STL) as the auxiliary release, giving a remote-trip capability for emergency-stop or interlock circuits.
Current Rating and Thermal Performance
That simplifies panel design: the same frame handles a 100 A load whether the enclosure sits in a conditioned room or near a heat source. Maximum power loss is 10 W, low enough that ventilation requirements are minimal for a single breaker.
This is the standard SENTRON 3VA2 frame footprint — it occupies the same panel cutout and bus-bar spacing as other 3VA2 3-pole units in the 100 A range. No rewiring or adapter plate needed if replacing a like-frame SENTRON MCCB.
Auxiliary Switch Configuration
The shunt trip release allows remote tripping, useful for emergency-off circuits or supervisory control.
