The adjustable thermal-magnetic trip unit covers 375 A to 2500 A, so you set the actual protection point in the field, not at the factory. Interrupting capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V. The 3-pole construction is standard for three-phase line protection. ## Built-in Indication and Auxiliary Hardware The breaker ships with a trip indicator, a voltage trigger, and a communication function plus an additional measurement function. That means the panel builder can wire the STL into an emergency-stop chain or a PLC-driven shutdown circuit without drilling into the breaker cover. That 105 mm width per 3-pole MCCB is standard for the SENTRON 3VA frame size — it fits the same mounting hole pattern as other breakers in the series, so a panel already laid out for a 3VA22 frame accepts this unit without re-drilling. ## Environmental and Power Handling","metaTitle":"Siemens 3VA2225-7KP32-0HH0 SENTRON MCCB, 250 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2225-7KP32-0HH0 molded case circuit breaker, 250 A continuous, 3-pole, 330 kA at 240 V.
