It's configured for line protection and carries an ETU320 electronic overcurrent release, which gives you adjustable thermal and magnetic trip curves for coordinating with downstream feeders. The shunt trip (STL) allows remote tripping from a pushbutton or safety circuit — useful when you need to kill power from a panel door without reaching the breaker handle. This MCCB carries a 242 kA breaking capacity at 240 V, dropping to 187 kA at 415 V and 440 V, then 121 kA at 500 V, and 6 kA at 690 V. The ETU320 release coordinates with these ratings, so the breaker clears fast enough to protect downstream gear without letting the arc sustain. ## Thermal derating — when the panel runs hot The 250 A rating holds steady up to 50 °C ambient — that's the sweet spot. Above that it starts to taper: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. The 3VA2225-6HL32-0KA0 measures 105 mm wide, 181 mm high, and 86 mm deep — that's a standard 3-pole MCCB footprint for this current class. The depth of 86 mm means it clears most standard enclosure depths, but check your gland plate clearance if you're running cables behind the breaker.","metaTitle":"Siemens 3VA2225-6HL32-0KA0 SENTRON MCCB, 250 A, 3-Pole, Line","metaDescription":"Siemens 3VA2225-6HL32-0KA0 SENTRON molded case circuit breaker, 250 A rated current, 3-pole, line protection, ETU320 release, shunt trip.
