Product details

The Siemens 3VA1163-6MH36-0BC0 is a 3-pole IEC frame 160 molded case circuit breaker rated at 63 A with a 70 kA breaking capacity at 415 V AC (class H). It is configured for starter protection using a TM120M trip unit — magnetic-only, no overload function — so the overload protection is handled upstream by a separate motor starter or thermal relay. The short-circuit release is adjustable from 5 to 15 times In, giving you flexibility to coordinate with downstream components.

The 63 A continuous rating matches a 37 kW motor at 400 V (roughly 60 A FLA) or a 45 kW motor if the service factor allows. The magnetic-only TM120M means this breaker does not provide thermal overload protection; it's intended for motor branch circuits where a separate overload relay handles the thermal curve. The undervoltage release (UVR) at 24 V DC will trip the breaker if control voltage is lost — common in emergency-stop chains or safety circuits where loss of power must open the motor circuit.

Frequently asked questions

Where can I buy 3VA1163-6MH36-0BC0 and how do I 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 is the closest alternative to 3VA1163-6MH36-0BC0 in the same family?

A direct alternative within the 3VA1 frame would be a variant with a different trip unit or accessory set — for example, a thermal-magnetic TM version instead of the magnetic-only TM120M. The frame, breaking capacity, and terminal style are shared, so the physical fit and SCCR remain the same; the choice depends on whether you need integral overload protection.

What compliance documentation does this brand provide for 3VA1163-6MH36-0BC0?

Siemens 3VA series breakers carry IEC 60947-2 certification, and typically UL/CSA listings for the North American market. RoHS and REACH declarations are available from the manufacturer. Specific certification marks for this order code should be verified against the product label or factory certificate.
