Product details

The Siemens 3VA1110-5MH36-0CA0 is a 3-pole IEC molded case circuit breaker on the 3VA1 frame, rated 100 A with a 55 kA breaking capacity at 415 V AC (class M).

Starter protection and release configuration

This breaker is configured for starter protection with a TM120M thermal-magnetic release, adjustable magnetic trip Ii from 5 to 15 times In (500–1500 A). The TM120M curve is sized for motor starting inrush — it rides through the acceleration transient without nuisance tripping, then clears a locked-rotor or phase-to-phase fault on the magnetic element. Note the description explicitly states "without overload protection" — the thermal element is present for short-circuit backup, but overload coordination relies on a separate overload relay in the starter assembly.

Undervoltage release and wiring

An integral undervoltage release (UVR) rated 120–127 V AC 50/60 Hz is factory-fitted. Clamp-type terminals accept copper conductors up to the frame's rated cross-section; no lug kit needed for standard panel wiring.

Frequently asked questions

What is the breaking capacity of this breaker?

Icu is 55 kA at 415 V AC, which is the class M rating on the 3VA1 IEC frame 160.

Does this breaker include overload protection?

No — the description states "without overload protection." The TM120M release provides short-circuit protection (magnetic trip adjustable 5–15 x In), but overload coordination requires a separate overload relay in the starter.

What voltage does the undervoltage release require?

The UVR is rated 120–127 V AC 50/60 Hz. It trips the breaker when control voltage drops below approximately 70% of that range.

Where can I buy 3VA1110-5MH36-0CA0 and how is it quoted?
