The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. It uses a TM240 thermal-magnetic overcurrent release and includes a shunt trip (STL) as the auxiliary release. The 3VA1150-5EF36-0JA0 measures 70 mm deep, 76.2 mm wide, and 130 mm high. The 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm module positions on a DIN rail or a panel-mount base plate. The 70 mm depth means it clears most standard enclosure back-panels without a deep-can extension. Front protection is IP40, which is typical for a panel-mounted breaker — it keeps out tools and fingers but is not sealed against washdown. Mount it inside a cabinet, not on an open wall in a wet area.","metaTitle":"Siemens SENTRON 3VA1150-5EF36-0JA0 MCCB, 50 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1150-5EF36-0JA0 molded case circuit breaker, 3-pole, 50 A rated current, 187 kA breaking capacity at 240 V.

The 3VA1150-5EF36-0JA0 carries 50 A continuous and 187 kA at 240 V, while the 3VA1110-5EE32-0JA0 is sized for a lower ampacity and fault duty. They share the same 3-pole SENTRON platform and similar dimensions, but the trip unit and breaking capacity differ — you cannot drop one in for the other without verifying the fault-current study and load current."},{"question":"What is the depth of 3VA1150-5EF36-0JA0?","answer":"The depth is 70 mm. That is the body depth from the mounting surface to the front of the breaker, not including any handle projection."},{"question":"What is the width of 3VA1150-5EF36-0JA0?","answer":"The width is 76.2 mm, which is standard for a 3-pole MCCB on a 25.4 mm module pitch."},{"question":"Will 3VA1150-5EF36-0JA0 drop into a panel specified around 3VA1110-5EE32-0JA0?","answer":"The physical dimensions are the same — 70 mm deep, 76.2 mm wide, 130 mm high — so it will fit the same mounting footprint and bus-bar spacing. However, the trip unit and interrupting rating are different, so the panel's short-circuit rating and load current must be re-verified before substitution."},{"question":"What compliance documentation does Siemens provide for 3VA1150-5EF36-0JA0?","answer":"The SENTRON 3VA series carries the standard Siemens declarations — RoHS, REACH, and IEC/UL certifications are available through the Siemens Industry Online Support portal.
