The Siemens SENTRON 3VA2325-6HL32-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 250 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That flat thermal curve simplifies panel design when the breaker sits near other heat sources. Breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V. The shunt trip lets a remote signal — from a safety relay, PLC, or emergency-stop circuit — open the breaker independently of the overcurrent mechanism.
The 138 mm width for a 3-pole 250 A frame is standard for SENTRON 3VA2 breakers — it drops into the same mounting footprint as other 3VA2 three-pole units, so a panel laid out for a 3VA2116-5HL32-0AK0 accepts this breaker without re-drilling the gland plate or reworking the bus bars. Maximum power loss is 37.5 W at rated load. That's moderate for a 250 A frame; factor it into enclosure ventilation if the panel is sealed or densely packed.
That is unusual for a compact MCCB and simplifies coordination studies in warm enclosures. The storage floor matters for unheated warehouses in cold climates — the breaker can sit at -40 °C without damage, as long as it's not energized until it warms to within the operating band.
