The TM240 thermal-magnetic overcurrent release handles the overload and short-circuit trip curves; there is no undervoltage release, no phase-failure detection, and no communication module onboard — this is a straight feeder breaker, not a smart panel device. The interrupting capacity drops with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. ## Thermal derating — the real-world current you can pull Above that it derates: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel internal ambient runs 60 °C, plan for 30 A continuous, not 32. The 3-pole frame width of 76.2 mm is standard for this SENTRON 3VA frame size; it mounts on a DIN rail or panel-mount plate with the same footprint as other 3VA1-series breakers. The integrated auxiliary trip accessory is order code 3VA9688-0BL33 — order it alongside if you need the shunt trip wired at the factory rather than field-installed.","metaTitle":"Siemens 3VA1132-5EF36-0KH0 SENTRON MCCB, 32 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1132-5EF36-0KH0 molded case circuit breaker, 32 A rated continuous current, 187 kA interrupting at 240 V.
