The Siemens 3VA1110-5MH36-0AE0 is a 3VA1 IEC frame 160 molded-case circuit breaker (MCCB) with a breaking capacity class M, rated Icu=55kA at 415 V. It's a 3-pole unit, In=100A, fitted with a TM120M thermal-magnetic trip unit for starter protection. There's no overload protection module here — this variant is configured for short-circuit protection only, with an adjustable instantaneous pickup Ii=5...15 x In. The clamp-type terminals accept the main conductors, and it ships with four auxiliary switches (HQ type) pre-installed.
Panel builders will note the clamp connection saves a few minutes per termination versus lug-torqueing, and the four HQ auxiliary switches give you status feedback for the PLC or a remote annunciator without adding a separate contactor block. The 55 kA SCCR at 415 V means this breaker can interrupt fault currents up to that level without cascading upstream — useful for a main or large-feeder position in a distribution board where the transformer rating pushes the available fault current high.
