The interrupting capacity climbs with the voltage curve: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. It carries a communication function onboard, so you get remote monitoring or trip indication without an add-on module taking up extra DIN space. No undervoltage release fitted, so if the application needs UVR for motor-start interlocking, that's a separate accessory. The 250 A full-scale value and the 375 A minimum define the adjustable thermal-magnetic or electronic trip range — you set the long-time pickup somewhere between those numbers to match the cable or load. The 48 W maximum power loss matters for enclosure heat rise: in a sealed panel at 70 °C ambient, that's 48 W the ventilation or air conditioning has to pull out.","metaTitle":"3VA2225-5JQ32-0AH0 SENTRON MCCB, 250 A, 3-Pole, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2225-5JQ32-0AH0 molded case circuit breaker, 250 A continuous, 3-pole, 187 kA interrupting at 240 V.
