Breaking capacity is the headline spec here: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V and 690 V. The 415 V and 440 V ratings (154 kA and 121 kA) still cover most European and Asian industrial distribution levels with headroom. ## Integrated accessories and wiring note The two HQ auxiliary switches provide position feedback (open/closed) to a DCS or status lamp. No undervoltage release is fitted on this order code, so if you need UVR for undervoltage protection on a motor feeder, this is not the variant. Dimensions: 130 mm height, 76.2 mm width (3 inches — standard MCCB footprint for panel busbar spacing), 70 mm depth. The 3-pole block occupies three 18 mm pole positions on a DIN rail or direct-mount plate. The shunt trip coil and auxiliary switches are rated for the same ambient envelope, but verify the shunt trip control voltage matches your panel's auxiliary supply — the evidence does not list the coil voltage on this order code.","metaTitle":"Siemens 3VA1150-6EF32-0HC0 SENTRON MCCB, 50A, 220kA at 240V","metaDescription":"Siemens SENTRON 3VA1150-6EF32-0HC0 molded case circuit breaker, 3-pole, 50A rated at 40°C, 220kA breaking capacity at 240V AC.

The 3VA1150-6EF32-0HC0 carries a higher continuous rating (50 A vs the 3VA1110 variant's lower rating) and includes a shunt trip release. If the original panel was wired for a shunt trip, it drops in without rewiring; if not, the shunt trip terminals simply remain unconnected."},{"question":"What compliance documentation does this brand provide for 3VA1150-6EF32-0HC0?","answer":"Siemens SENTRON MCCBs carry CE marking for the European market and are designed to IEC 60947-2. UL and CSA listings are standard for the series, though the specific order code should be verified against the UL file for the exact interrupting ratings at 480Y/277 V.
