That TM240 designation means the thermal element is fixed at 200 A, so the breaker carries its full 200 A continuously at 40 °C ambient — no derate needed until the panel hits 55 °C, where it drops to 194 A, and down to 176 A at 70 °C. The interrupting ratings climb steeply with voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. For a 480 V distribution panel, that 75.6 kA at 440 V (the nearest published point) puts it well above typical 65 kA SCCR requirements, giving headroom for high-fault utility feeds or transformer secondaries. ## Integration and mounting — panel fit The TM240 release is a fixed-thermal, fixed-magnetic design — no interchangeable trip units. That simplifies coordination: the thermal curve is fixed, so the breaker's long-time pickup is always 200 A, and the magnetic instantaneous pickup is set by the TM240's factory calibration (typically 10x In, though the exact multiple depends on the TM240 variant).","metaTitle":"Siemens 3VA1220-5EF32-0BA0 SENTRON MCCB, 200 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1220-5EF32-0BA0 molded case circuit breaker, 200 A at 40 °C, 3-pole, TM240 release, 187 kA at 240 V.
