That means a panel running warm — say 55 °C inside the enclosure — you lose 12 A off the headline number. The adjustable thermal-magnetic trip is set from a minimum of 375 A to a maximum of 2 500 A, with the full-scale value at 250 A. Initial trip setting is 50 A, so this unit ships set low and needs field adjustment to match the load. No auxiliary switch is fitted from the factory, so if you need status feedback, plan for an add-on module.","metaTitle":"Siemens 3VA2225-6JQ32-0KA0 SENTRON MCCB, 250 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA2225-6JQ32-0KA0 molded case circuit breaker, 250 A rated at 40 °C, 3-pole, 242 kA at 240 V.
