It is a starter-protection variant with a TM120M thermal-magnetic trip unit, set for motor starting duty without overload protection — meaning the thermal element is bypassed and only the magnetic short-circuit protection is active, adjustable between 5 and 15 times the rated current (Ii=5…15 x In). This makes it a magnetic-only breaker for motor short-circuit protection where overload protection is handled separately by a contactor/overload relay combination. The magnetic-only trip (Ii=5…15 x In) means it will hold through motor inrush without nuisance tripping, but it will NOT provide overload protection; pair it with a properly sized overload relay on the contactor. The clamp connection accepts copper or aluminum conductors without lug kits, saving panel space and install time. ## Where it lives in the panel The 3-pole, 125 A frame fits in a standard MCCB footprint; plan for at least 75 mm of width per pole plus clearance for the auxiliary switch and trip alarm switch wiring.","metaTitle":"Siemens 3VA1112-6MH36-0AG0 Circuit Breaker, 125A, 70kA @ 415","metaDescription":"Siemens 3VA1112-6MH36-0AG0 IEC frame 160 circuit breaker, 125A, 70kA breaking capacity @ 415V.
