The Siemens SENTRON 3VA2325-6HN32-0AJ0 is a 3-pole molded case circuit breaker rated 250 A continuous with a 3000 A frame — that frame size tells you the internal mechanism and contact structure are built for the full 3000 A interrupting duty, even though the continuous trip is set at 250 A. This matters for selectivity: you get the mechanical endurance and arc-chamber volume of a 3000 A frame while protecting a 250 A feeder. Interrupting capacity is where this part earns its place in a high-fault panel: 242 kA at 240 V, 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V. Maximum power loss is 37.5 W, which keeps the enclosure heat rise predictable for the guy laying out the gland plate and ventilation.
Integration and footprint
At 110 mm deep, 138 mm wide, and 248 mm tall, this MCCB fits the standard SENTRON 3VA2 panel footprint. The 138 mm width per 3-pole unit matches the typical DIN-rail or mounting-plate pitch in a distribution board — no surprises when you're laying out busbars or phase barriers. It is a straight line-protection breaker — the basic switch is order code 3VA2325-6HN32-0AA0. If you need those options, you step to a different suffix in the 3VA2 family.
