3VA4125-5ED14-0AA0 - 25 Amp Circuit Breaker

3VA4125-5ED14-0AA0 - 25 Amp Circuit Breaker

Safeguard your electrical panel with the Siemens 3VA4125-5ED14-0AA0, a precision 25-amp, single-pole molded-case circuit breaker engineered for dependable protection in commercial, light industrial, and residential systems. Incorporating a TM210 thermal-magnetic trip unit with fixed Ir and Ii settings, this breaker responds swiftly to overcurrents and short circuits—shielding your wiring and connected devices. Despite its strong protection capability, it remains compact (just 5.09 inches tall, approximately 0.28 kg) and fits cleanly into tight panel spaces. With a 35 kA interrupting rating at 277 V AC, it handles high fault currents reliably, maintaining safety even under demanding conditions.
