The Siemens SENTRON 3VA2025-6JP46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 25 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
This MCCB delivers 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V. For selectivity coordination downstream, the ETU550's adjustable I²t curves let you stage trip times against smaller branch breakers.
The breaker occupies 140 mm width, 181 mm height, and 86 mm depth — a standard SENTRON 3VA2 frame footprint. An optional motor drive (product extension) is available for remote switching, and the communication function supports integration with higher-level control systems without an external gateway.
