Product details

What this 3VA1 breaker carries

The Siemens 3VA1163-5MH32-0AF0 is a 3-pole IEC frame 160 molded case circuit breaker with a 63 A thermal-magnetic trip unit (TM120M, adjustable magnetic release Ii=5...15 x In). This variant is configured for starter protection: the TM120M trip provides short-circuit-only protection (no overload function), so it pairs with a separate overload relay ahead of a motor starter.

What's in the box

The order code includes a nut keeper kit (for captive mounting hardware on the panel gland plate) and two auxiliary contacts: one HQ auxiliary switch and one HQ trip alarm switch. These are factory-fitted, so you don't need to order them separately or open the breaker cover.

Frequently asked questions

What does the TM120M trip unit mean for motor protection?

TM120M is a thermal-magnetic trip with a fixed thermal rating of 63 A and an adjustable magnetic short-circuit release (Ii=5...15 x In). The 'M' suffix indicates it provides short-circuit protection only — no overload protection — so it must be paired with a separate overload relay for motor starting duty.

Where can I buy 3VA1163-5MH32-0AF0?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What compliance documentation is available for this breaker?

The 3VA1 series carries IEC certification (IEC 60947-2) as standard. Compliance documentation including RoHS and REACH declarations is typically provided by Siemens on request.
