It carries the TM120M thermal-magnetic release tuned for starter protection — note the 'without overload protection' qualifier in the order-code suffix, meaning this variant is configured for short-circuit protection only (Ii adjustable 5...15 x In), intended to pair with a separate overload relay in a motor starter assembly. The clamp-type terminals accept standard power conductors, and the factory-fitted 2 auxiliary switches (HP type) provide status feedback to the PLC or safety circuit. For motor starter duty, the adjustable short-circuit release (Ii = 5...15 x In, so 625...1875 A) lets you coordinate with the downstream contactor and overload relay, avoiding nuisance trips on inrush while still protecting the cable. The IEC frame 160 means the physical footprint and terminal spacing match standard 160 A frame accessories (busbars, plug-in bases, door interlocks). ## Deployment context The clamp terminals accept copper or aluminum conductors typical of 125 A motor feeders. The two auxiliary switches (HP) give the PLC a positive indication of breaker state — useful for safety interlocks or remote monitoring in a motor control scheme.","metaTitle":"Siemens 3VA1112-5MH36-0AB0 Circuit Breaker, 125A, 55kA @ 415","metaDescription":"Siemens 3VA1112-5MH36-0AB0 IEC frame 160 MCCB, 125A, breaking capacity class M Icu=55kA @ 415V.
