The thermal-magnetic trip unit is a TM120M set at In=100A, configured for starter protection (AM characteristic) — meaning the thermal element is sized for motor inrush without nuisance tripping, while the magnetic short-circuit pickup Ii is adjustable from 5 to 15 times In (500A to 1500A). Note the description explicitly states \"without overload protection\" — this breaker provides short-circuit protection only; the overload function is handled upstream by a separate overload relay or motor starter. The undervoltage release (UVR) is wound for 120-127V AC 50/60Hz and will trip the breaker if control voltage drops below its dropout threshold, a standard safety feature for conveyors or pumps that must not auto-restart after a power loss. ## Integration notes The clamp terminals accept copper or aluminum conductors — strip length and torque spec follow the manufacturer's mounting instructions. The auxiliary switches (2 HQ) and trip alarm switch (1 HQ) are factory-integrated, so no add-on accessory block is needed for remote status indication. The UVR coil draws its control power from the 120-127V AC supply; if your panel uses a different control voltage (e.g., 24V DC or 230V AC), this specific UVR variant will not operate — you would need a different order code with the matching undervoltage release coil.","metaTitle":"Siemens 3VA1110-5MH36-0CH0 Circuit Breaker, 55kA @ 415V, 100","metaDescription":"Siemens 3VA1110-5MH36-0CH0 IEC frame 160 MCCB, 55kA breaking capacity @ 415V, 100A, starter protection TM120M, UVR 120-127V AC.
