Above that, the thermal curve drops it to 495 A at 55 °C, 490 A at 60 °C, 485 A at 65 °C, and 480 A at 70 °C. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, and 52.5 kA at 690 V. At 415 V, 242 kA still clears most industrial fault levels; at 690 V the 52.5 kA rating is typical for a 500 A frame and suits the majority of 690 V distribution. The ETU350M electronic trip unit handles the overcurrent protection — adjustable long-time, short-time, and instantaneous settings via the front dials. An undervoltage release (UVR) is fitted as standard — the part includes the 3VA9608-0BB25 auxiliary trip module. That means the breaker drops out on loss of control voltage, which is common in safety circuits and emergency-stop chains. No auxiliary contacts are included; if you need status feedback to a PLC, order the contact block separately. The basic switch assembly carries the order code 3VA2450-7MN32-0AA0. If you are replacing only the internal switch mechanism (not the entire breaker), that is the sub-assembly to order. The auxiliary trip module is 3VA9608-0BB25. The 15 000 latching endurance cycles is typical for a 500 A MCCB in distribution duty — not intended for frequent switching like a contactor, but fine for isolation and backup protection.","metaTitle":"Siemens SENTRON 3VA2450-7MN32-0DA0 MCCB, 500 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2450-7MN32-0DA0 molded case circuit breaker, 3-pole, 500 A rated, 330 kA at 240 V.
