The Siemens 3VA2325-5HL32-0CL0 is a SENTRON 3VA2 molded case circuit breaker rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Three-pole construction, line-protection design, with an interrupting capacity that climbs to 187 kA at 240 V and still delivers 121 kA at 415 V and 440 V. At 690 V it holds 7.5 kA, which matters when you're coordinating downstream in a mining substation where fault current can hit hard.
What the interrupting ratings mean for your panel
The 187 kA at 240 V and 121 kA at 415 V tell you this breaker can clear a bolted fault upstream of a crusher drive without rupturing. The 7.5 kA at 690 V is the ceiling for that voltage class — still enough for most 690 V mining distribution. If your system SCCR at the point of common coupling is known, these numbers confirm whether this MCCB gives you the headroom you need without cascading upstream.
Built-in auxiliary and release complement
This variant ships with two auxiliary switches, one trip alarm switch, one electrical alarm switch, and an undervoltage release. That means you get remote status and trip indication out of the box — no separate accessory order for basic signaling. The UVR (undervoltage release) protects against automatic restart after a voltage dip, a standard requirement for conveyor and mill motor feeds.
