Those are the maximum fault currents it can safely clear at each voltage level. In a 480 V panel with an available fault current of 200 kA, this breaker is comfortably within its 330 kA rating at 440 V — no need to cascade an upstream current-limiting fuse. ## Panel fit — dimensions and mounting The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most 600 V panelboards and enclosure backplates without crowding adjacent poles. The ETU320 trip unit is field-adjustable via rotary dials on the front, so you can set the long-time pickup and short-time pickup without pulling the breaker.","metaTitle":"Siemens 3VA2025-8HL36-0AA0 SENTRON MCCB, 25 A, ETU320, 440 k","metaDescription":"Siemens 3VA2025-8HL36-0AA0 SENTRON molded case circuit breaker, 25 A continuous, ETU320 electronic trip, 440 kA at 240 V.
