Product details

The Siemens 3VA1110-6MH36-0HA0 is a 3-pole IEC frame 160 molded case circuit breaker with a 100 A rated current (In) and a class H breaking capacity of 70 kA at 415 V AC. This variant is configured for starter protection with a TM120M thermal-magnetic trip unit set to 100 A, but note the description explicitly states "without overload protection" — the TM120M provides only short-circuit protection (Ii adjustable 5...15 x In). Overload protection must be handled externally, typically by a separate overload relay in the motor starter assembly.

The breaker uses clamp (box lug) connections, accepting copper or aluminum conductors sized for the 100 A rating. The shunt trip terminals are separate from the main power path — verify polarity on the DC supply (12-30 V DC) and that the AC supply (24 V AC) is from the same phase as the breaker's line side to avoid nuisance trips from voltage sags.

Frequently asked questions

Where can I buy 3VA1110-6MH36-0HA0 and how do I get a price?

This part is sourced to order through independent distribution. Submit an RFQ to confirm current availability and pricing — no stock or price figures are published here, but a quote can be generated on request.

What does the 70 kA breaking capacity at 415 V mean for my installation?

The 70 kA Icu (ultimate breaking capacity) at 415 V AC means this breaker can safely interrupt a fault current up to 70,000 amps without failing. This is a class H rating, suitable for high-fault-current locations such as near large transformers or in industrial switchgear where lower-rated breakers would require upstream fuses or current-limiting reactors.

Does this breaker include overload protection?

No. The description states "without overload protection." The TM120M trip unit provides only short-circuit protection (adjustable Ii = 5...15 x In). Overload protection must be provided by a separate device, such as a thermal overload relay in the motor starter.
