It ships with a TM240 thermal-magnetic trip unit, adjustable overload protection from 35 A to 50 A, and short-circuit pickup adjustable from 5 to 10 times In. The clamp connection terminals and three factory-fitted HQ auxiliary switches make this a line-protection breaker ready for panel wiring. In a 400 V industrial distribution board, that puts it in the medium-high range for IEC frame 160 hardware; it coordinates well downstream of a larger-frame feeder without requiring a current-limiting fuse upstream. The adjustable Ir (35–50 A) lets you match the thermal pickup to the actual continuous load rather than the fixed In, so you can run the breaker at 40 A on a 45 A circuit without nuisance tripping. ## Deployment context The clamp connection terminals accept copper or aluminum conductors without lug kits — speeds up panel wiring for OEMs and retrofit jobs. The three HQ auxiliary switches give remote status feedback (open/closed/tripped) without adding a separate auxiliary block.","metaTitle":"Siemens 3VA1150-5EF36-0AD0 Circuit Breaker, 55kA @ 415V, 50A","metaDescription":"Siemens 3VA1150-5EF36-0AD0 IEC frame 160 circuit breaker, 55kA breaking capacity at 415V, 3-pole, 50A adjustable thermal-magnetic protection.
