Its interrupting capacity reaches 187 kA at 240 V, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V — figures that define its fault-clearing capability in a distribution panel. Rated 50 A continuously at 40 °C, the breaker derates to 45 A at 70 °C — a 10% drop that matters when the MCCB sits in a crowded enclosure with other heat sources. The TM240 release means the thermal element is calibrated for a 240 A frame; the magnetic trip setting is fixed within that frame. This is a line-protection device, not a motor-protective breaker — no adjustable magnetic pickup for inrush. At 14.6 W maximum power loss, the heat dissipated into the panel is modest for a 50 A MCCB — roughly equivalent to a small relay coil — but verify the enclosure's thermal budget if multiple breakers are ganged. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a compact 3-pole MCCB footprint that fits standard panel-mount cutouts. ## Compliance Documentation As a SENTRON-series MCCB, this breaker carries the manufacturer's standard compliance documentation package — typically including RoHS, REACH, and IEC/UL certifications for the 3VA platform. Specific cert numbers are verified against the nameplate at receipt.","metaTitle":"3VA1150-5EF36-0AG0 SENTRON Molded Case Circuit Breaker, 50 A","metaDescription":"3VA1150-5EF36-0AG0 SENTRON molded case circuit breaker, 3-pole, 50 A rated at 40 °C, interrupting capacity 187 kA at 240 V.
