Siemens 3VA1110-5MH36-0AA0 3VA1 100A 55kA 3-Pole Magnetic Protection Molded Case Circuit Breaker

The Siemens 3VA1110-5MH36-0AA0 is a 3-pole molded case circuit breaker from the SENTRON 3VA1 series, rated 100 A with a breaking capacity of 55 kA at 415 V AC. It provides magnetic-only protection, making it suited for motor branch circuits and starter protection applications where thermal overload is handled separately downstream.

Applications & Use Cases

Magnetic-only protection in the 3VA1110-5MH36-0AA0 means the trip characteristic responds exclusively to instantaneous overcurrents — short circuits and severe fault currents — without a thermal element for sustained overload. This is the correct configuration when a separate motor overload relay or soft starter handles the thermal protection curve, keeping the MCCB focused on fault clearing at its 55 kA breaking capacity.

At 150 × 92 × 116 mm and 1.006 kg, the 3VA1 frame fits standard IEC switchboard busbar pitches without requiring extended depth. Three-pole configuration covers standard three-phase 415 V distribution and motor feeder circuits up to 100 A frame size.
