Breaking capacity is the real selector here: 121 kA at 240 V, 75.6 kA at 415 V, 25 kA at 440 V, and 11.9 kA at 690 V. The 690 V rating is useful for 600 V class North American systems or mining gear running 690 V. Panel fit: 105 mm wide, 158 mm tall, 70 mm deep. ## Trip unit and auxiliary contacts — what you get out of the box The TM240 overcurrent release is a fixed thermal-magnetic design — no electronic adjustment, no communication module, no voltage trigger. If you need those, you are looking at a different 3VA variant with the electronic trip. That storage floor matters if the spare sits in an unheated warehouse over a northern winter.","metaTitle":"Siemens 3VA1216-4EF32-0AB0 SENTRON MCCB, 160 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1216-4EF32-0AB0 SENTRON molded case circuit breaker, 160 A rated current, 3-pole, TM240 thermal-magnetic trip, 121 kA at 240 V.
