Product details

The Siemens SENTRON 3VA2125-0HM46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 25 A continuous current, with an adjustable overcurrent release (ETU330) spanning 38 A to 300 A. Its interrupting capacity hits 440 kA at 415 V and 187 kA at 690 V — numbers that matter for high-fault panels where upstream coordination is tight. The electronic trip unit gives you curve shaping for selectivity, not just thermal-magnetic fixed curves.

At 86 mm deep, 140 mm wide, and 181 mm tall, this MCCB fits standard SENTRON 3VA panel cutouts and busbar systems.
