Product details

63 A MCCB with shunt trip — line protection for distribution panels

The Siemens SENTRON 3VA1163-5EF32-0KA0 is a 3-pole molded case circuit breaker rated for 63 A continuous at 40 °C, with a TM240 thermal-magnetic overcurrent release and an integrated shunt trip (STL) for remote tripping. The 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit standard SENTRON panel footprints — no rework needed for a drop-in replacement in an existing 3VA1 lineup.

This MCCB delivers 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. The TM240 release is fixed, so no field adjustment of the thermal or magnetic trip settings.

For BOM freeze or line-down situations, the active lifecycle means no last-time-buy pressure — but always confirm lead time at quote, as industrial MCCB demand can tighten supply windows.

Frequently asked questions

Where can I buy 3VA1163-5EF32-0KA0 and get a price?

This part is sourced to order against an RFQ through independent distribution. Submit a request for quote — availability and current pricing are confirmed at quote time.

What is the breaking capacity of this MCCB at 240 V?

187 kA at 240 V, which covers high-fault industrial distribution panels without cascading upstream breakers.

What is the width of 3VA1163-5EF32-0KA0?

76.2 mm (3 in), matching the standard SENTRON 3-pole MCCB footprint for drop-in replacement.

Does this breaker include a shunt trip?

Yes, it has a shunt trip (STL) auxiliary release for remote tripping, part of the 3VA1 design.
