The TM220 release means the thermal element carries the 400 A frame rating, and the magnetic pickup is fixed at 10× In (4 000 A) for instantaneous short-circuit protection. ## Interrupting capacity by voltage — what it means for panel SCCR At 240 VAC the breaker clears 187 kA symmetrical; at 415 VAC and 440 VAC it holds 121 kA; at 500 VAC it still manages 75.6 kA; at 690 VAC it drops to 11.9 kA. These are the numbers that govern panel SCCR — if your transformer secondary or generator bus can deliver 100 kA at 480 V, this breaker has headroom. ## Thermal derating — continuous current across ambient range At 55 °C it derates to 392 A; at 60 °C to 384 A; at 65 °C to 376 A; at 70 °C to 367 A. For a panel that runs hot — say a solar combiner or VFD lineup — the 55 °C derating is the one to budget against.","metaTitle":"Siemens SENTRON 3VA1340-5EE32-0AA0 MCCB, 400 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1340-5EE32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, 187 kA interrupting at 240 VAC.
