The 70 mm depth, 76.2 mm width, and 130 mm height fit the standard SENTRON 3VA footprint — it mounts on a DIN rail or panel-mount plate in the same cutout as other 3VA frame sizes. It ships with 2 auxiliary switches (HP type) built in — those are the normally-open/normally-closed contacts that signal the breaker's position to a PLC or status lamp. If you need those functions, you add external modules or look at a different 3VA variant with those options populated. The 76.2 mm width (3-pole) is the critical dimension for DIN-rail spacing — it takes three 18 mm module positions on a standard DIN rail, same as any other 3-pole MCCB in the 3VA family. The TM240 release is fixed thermal and magnetic; no dials to set, so once it's installed, the protection curve is locked. The 2 auxiliary switches are wired to terminals on the front; they're rated for 240 V AC / 24 V DC control circuits typically.","metaTitle":"Siemens 3VA1150-5EF36-0AB0 SENTRON MCCB, 50 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1150-5EF36-0AB0 SENTRON molded case circuit breaker, 50 A rated continuous current, 3-pole, 187 kA interrupting at 240 V.
