The Siemens SENTRON 3VA2325-7MN32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated 250 A continuous at 40 °C, with the same rating holding all the way up to 70 °C — no derating needed across that range. That makes it a solid pick for a warm panel where you don't want to lose headroom as ambient climbs. It's designed for motor protection, so it includes phase failure detection and an undervoltage release (UVR) built in, plus a full auxiliary switch complement: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type).
Interrupting capacity and selectivity
The interrupting capacity is where this breaker earns its keep: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. That 330 kA at 240 V is high enough for most large-service entrance or sub-distribution panels where fault current can be extreme. At 690 V the rating drops sharply to 7.5 kA — still fine for a motor branch circuit on a 690 V line, but you'd check selectivity coordination if you're feeding a downstream panel.
Physical fit and wiring
The breaker measures 248 mm high, 138 mm wide, and 110 mm deep. That 110 mm depth is worth noting if you're retrofitting into an existing panel that was designed around a different MCCB — measure the gutter space and door clearance before committing. The basic switch order code is 3VA2325-7MN32-0AA0, which is the frame and trip unit assembly; the -0CL0 suffix adds the auxiliary switches and UVR. Power loss at full load is 40 W max, so factor that into your panel thermal budget.
