The Siemens SENTRON 3VA2025-8HN36-0AA0 is a 3-pole molded case circuit breaker (MCCB) rated for 25 A continuous current, designed for line protection in distribution panels and industrial feeder circuits.
Breaking capacity and where it matters
Rated breaking capacity reaches 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 — these figures tell you the maximum fault current the breaker can safely interrupt at each voltage level, critical for SCCR compliance at the panel level. The 25 A rating holds flat across the full ambient temperature range from -25 °C to 70 °C, so no derating is needed in a warm enclosure.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — standard MCCB footprint for a 3-pole SENTRON frame, fitting common panel cutouts and busbar arrangements.
