Product details

Siemens SENTRON 3VA1163-3EF32-0BH0 — 63 A MCCB with Undervoltage Release

The Siemens SENTRON 3VA1163-3EF32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A at 40 °C and derating to 58 A at 70 °C. Its interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — figures that govern fault-clearing coordination downstream.

Above that, the thermal-magnetic trip unit derates: 62 A at 55 °C, 60 A at 65 °C, 58 A at 70 °C.

Built-in Auxiliary Switches and Undervoltage Release

The auxiliary switch complement (2 form-C contacts + 1 trip alarm switch) fits standard 3VA accessory slots; no extra wiring space needed beyond the breaker's own terminal layout. The trip indicator (mechanical flag) gives a local visual confirmation of trip cause without opening the panel door.

Frequently asked questions

Where can I buy 3VA1163-3EF32-0BH0 and get a price?

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

What are the key ratings for 3VA1163-3EF32-0BH0?

Rated 63 A at 40 °C (derated to 58 A at 70 °C), with a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V. It is a 3-pole MCCB with an integrated undervoltage release and 2 auxiliary switches plus a trip alarm switch.

What is the depth of 3VA1163-3EF32-0BH0?

The depth is 70 mm (2.76 in), with a width of 76.2 mm (3 in) and height of 130 mm (5.12 in).

Does 3VA1163-3EF32-0BH0 include an undervoltage release?

Yes, the auxiliary release type is an undervoltage release (UVR), which trips the breaker when control voltage drops below the dropout threshold.
