It holds that same 500 A rating up through 50 °C, then derates stepwise to 452 A at 70 °C (–) — useful if the panel runs hot near a drive stack or transformer. Breaking capacity hits 220 kA at 240 V and still delivers 154 kA at 415 V and 440 V (–), so it handles high-fault industrial services without cascading upstream. The TM240 thermal-magnetic release is adjustable, letting you dial the long-time pickup to match cable or busway ampacity rather than locking in a fixed trip. Dimensions are 248 mm high, 138 mm wide, 110 mm deep (–) — a standard MCCB footprint for 500 A frames. Storage range from -40 °C to 80 °C (–) covers unheated warehouses; operating range is -25 °C to 70 °C (–).","metaTitle":"Siemens 3VA1450-6EF32-0AA0 SENTRON MCCB, 500 A, 220 kA at 24","metaDescription":"Siemens SENTRON 3VA1450-6EF32-0AA0 molded case circuit breaker, 500 A rated current, 220 kA breaking capacity at 240 V.
