The Siemens 3VA2225-8HL32-0DA0 is a SENTRON 3VA2 molded case circuit breaker rated for 250 A continuous current (at 40 °C through 50 °C) and designed for line protection. It is a 3-pole unit with an integrated undervoltage release (UVR) — the auxiliary release type is specified as undervoltage release. The supplied basic switch is order code 3VA2225-8HL32-0AA0.
Breaking capacity — what it means for fault duty
Breaking capacity is voltage-dependent and ranges from 440 kA at 240 V down to 52.5 kA at 690 V. At 415 V and 440 V it holds 330 kA; at 500 V it drops to 220 kA.
Thermal derating and ambient limits
Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
Trip indicator is not fitted; voltage trigger is absent.
