The TM110M thermal-magnetic release is adjustable up to 64 A (li max), so the same breaker body covers a wide motor FLA band by swapping the trip setting. At 440 V the interrupting rating drops to 63 kA, and at 500 V and 690 V it sits at 7.5 kA — still adequate for most industrial distribution but a signal to verify the available fault current at the point of installation. ## Starter protection version — what that means on the line This is the 'starter protection' variant of the 3VA platform, designed to sit ahead of a motor contactor and overload relay in a combination starter. The TM110M release provides short-circuit and overload protection in one package, saving panel space versus a separate MCCB plus thermal relay. The 4 A continuous rating matches small motors (typically up to 1.5 kW at 400 V) or control transformers. The breaker accepts optional motor drive (product extension optional yes), so it can be remotely tripped or reset via a shunt trip or undervoltage release — useful for emergency-stop circuits or automated restart sequences. Depth of 70 mm (2.8 in) leaves clearance for rear-mounted busbars or cable ducts in a typical 200 mm deep enclosure.","metaTitle":"3VA1104-5MG36-0AA0 SENTRON MCCB, 3-pole, 4 A, 187 kA at 240","metaDescription":"SENTRON 3VA1104-5MG36-0AA0 molded case circuit breaker, 3-pole, 4 A rated continuous current, 187 kA breaking capacity at 240 V.
