Siemens 3VA2225-8HL32-0BL0 — 250 A SENTRON MCCB for Line Protection
The Siemens 3VA2225-8HL32-0BL0 is a SENTRON molded case circuit breaker (MCCB) rated for 250 A continuous current at 40 °C, designed for line protection in industrial power distribution. Its 3-pole construction and 86 mm depth fit standard panel layouts, with a width of 105 mm and height of 181 mm. Breaking capacity is 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — covering high-fault installations across common voltage levels. Thermal derating is minimal up to 50 °C (still 250 A), then drops to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. The undervoltage release (UVR) is built in, and the auxiliary switch complement includes 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type).
Mounting and Integration
At 86 mm deep, 105 mm wide, and 181 mm tall, the 3VA2225-8HL32-0BL0 fits standard panel cutouts for 3-pole MCCBs. The supplied basic switch is order code 3VA2225-8HL32-0AA0. Maximum power loss is 50.5 W, which should be factored into enclosure thermal calculations.
