Its rated continuous current sits at 160 A, and it holds that rating all the way up to 50 °C ambient; at 55 °C it derates to 153.6 A, and at 70 °C it's still delivering 144 A. The breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That's high-interrupting-rated gear — it clears a fault without blowing apart or welding its contacts, and it gives you the SCCR headroom to coordinate downstream in a distribution panel without cascading failures upstream. The overcurrent release is a TM240 — a thermal-magnetic unit fixed at 160 A continuous, with an adjustable short-time delay (tr max. 1 s). It's not a voltage-trigger or ground-fault version, and there's no undervoltage release or communication module onboard. What you get is a straight-ahead line-protection breaker with three auxiliary switches HQ for status feedback back to the PLC or SCADA.
This MCCB is a panel-mount device — it bolts into a distribution board or a motor control center. Three auxiliary switches HQ come pre-installed — that's the '5EF32' in the order code. They give you normally-open/normally-closed contacts for tripped-status indication without needing a separate aux block. If your BOM calls for a breaker with aux contacts wired to a DI card, this saves a line item and a wiring step.
How this sits against the 3VA1112-5EF32-0CA0
The 3VA1112-5EF32-0CA0 has a lower continuous current rating than this 160 A frame. Same TM240 release family, same aux contacts, same footprint.
