Product details

Its 63 A continuous rating holds across 40 °C to 50 °C without derating, then steps down to 62 A at 55 °C and 58 A at 70 °C — useful to know if the breaker sits near other heat sources in a crowded enclosure. Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at 500 V and 690 V.

It drops into a standard SENTRON 3VA panel footprint; no rewiring needed if replacing a same-frame 3VA breaker.

Rated insulation voltage 800 V. Maximum power loss 17.3 W.

Frequently asked questions

Where can I buy 3VA1163-3EF32-0KA0 and how is it quoted?

This MCCB is sourced through independent distribution and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the breaking capacity of 3VA1163-3EF32-0KA0 at 415 V?

52.5 kA at 415 V. That's the figure to use for most 400 V industrial distribution panels when calculating SCCR coordination.

What does the TM240 release designation mean?

TM240 indicates a thermal-magnetic release with a 240 A frame rating. The breaker's continuous current is set by the 63 A rating plug — the TM240 frame gives headroom for higher-current variants in the same mechanical package.

Does this breaker include a shunt trip?

Yes, the 3VA1163-3EF32-0KA0 is equipped with a shunt trip (STL) for remote tripping via a control voltage. No undervoltage release is fitted.
