Product details

What the 70 kA rating means for your panel

The 3VA1163-6MH32-0AH0 is a Siemens 3VA1 IEC frame 160 circuit breaker with a breaking capacity class H rating of Icu=70kA at 415 V AC. The 63 A rated current (In) is set by the TM120M thermal-magnetic release, configured here for starter protection: the thermal element is sized for motor overload curves, and the magnetic short-circuit pickup is adjustable from 5 to 15 times In, giving you a range of 315 A to 945 A instantaneous trip.

Deployment context — what it connects to

The TM120M release is a dedicated motor-protection curve, meaning the thermal element tracks the heating characteristic of a motor winding rather than a generic cable. If you are using this as a motor branch-circuit protector, pair it with a separate overload relay (the description notes 'without overload protection' — the TM120M handles short-circuit only, not running overload).

Frequently asked questions

Where can I buy 3VA1163-6MH32-0AH0 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 does the 70 kA breaking capacity class H mean?

The Icu=70kA @ 415V rating means this breaker can safely interrupt a fault current up to 70,000 amps at 415 V AC without failing. Class H is the highest breaking capacity tier in the 3VA1 frame 160 range — it is specified when the available fault current at the panel exceeds the standard 25 kA or 36 kA class ratings, typically in large industrial distribution boards or transformer-fed switchgear.

What is the short-circuit protection setting range?

The magnetic short-circuit pickup (Ii) is adjustable from 5 to 15 times the rated current In (63 A), giving an instantaneous trip range of 315 A to 945 A. This is set via the dial on the front of the TM120M release.
