The Siemens SENTRON 3VA2325-6HL32-0CL0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current, designed for line protection in distribution panels and industrial switchgear. Its breaking capacity is 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — the 690 V figure is the limiting case for high-voltage low-fault applications, so verify the available fault current at your system voltage before specifying. The continuous current rating holds at 250 A across the full ambient range from 40 °C to 70 °C, meaning no derating is needed for elevated panel temperatures up to that limit.
Auxiliary Switching and Release Configuration
This MCCB is equipped with 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type), plus an undervoltage release (UVR). A trip indicator is present for quick visual identification of a fault trip, and the breaker does not include a voltage trigger or communication function.
Physical Integration and Environmental Limits
Dimensions are 248 mm height, 138 mm width, and 110 mm depth — a standard 3-pole MCCB footprint that fits most Siemens SENTRON mounting bases and panel cutouts. Operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C, covering most indoor industrial environments without special enclosures. Maximum power loss is 40 W, which should be factored into enclosure thermal calculations for densely populated panels.
