At 55 °C it still carries 242.5 A, and at 60 °C it's 237.5 A. The interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still holds 85 kA at 440 V. It's fitted with the ETU860 electronic trip unit, which gives you adjustable short-time delay (tsd) from 0.05 s to 0.5 s — useful for selective coordination downstream. The unit also includes a ground-fault monitoring function using summation current formation on L + N. Communication function is built in, so this breaker talks back to the control system without an add-on module. The case dimensions are 248 mm high, 184 mm wide, and 110 mm deep. It's a standard panel-mount MCCB footprint for the 250 A class — you're looking at a cutout that clears the 184 mm width and enough depth for the rear terminals plus wiring space. ## Who needs this breaker It's a line-protection MCCB, so it's your main or feeder breaker in a 4-wire (3-phase + neutral) distribution panel. The ETU860 trip unit with adjustable time delays and ground-fault detection makes it a strong candidate for selective coordination studies and for protecting circuits where nuisance tripping is a concern.","metaTitle":"Siemens 3VA2325-6KQ42-0AA0 SENTRON MCCB, 250 A, 4-Pole, 242","metaDescription":"Siemens SENTRON 3VA2325-6KQ42-0AA0 molded case circuit breaker, 250 A continuous, 4-pole, 242 kA at 240 V.
