SIEMENS
Siemens SENTRON residual current operated circuit breaker (RCCB) is a reliable 4-pole protection device. Featuring a Type A rating, it offers high-performance protection against sinusoidal AC residual currents and pulsating DC residual currents.
The Siemens 5SV3346-6 is a high-performance residual current operated circuit breaker (RCCB) designed for reliable electrical protection. This 4-pole Type A breaker ensures safety against earth faults, overloads, and electrical leakage in residential, commercial, and industrial installations. With a rated current of 63 A and a sensitive 30 mA trip threshold, it offers superior protection for both people and equipment. Operating at a nominal voltage of 400 V AC, it is an ideal solution for modern electrical networks requiring dependable and precise protection.
Enhanced Personnel and Fire Protection: The sensitive 30 mA tripping current ensures rapid disconnection, effectively preventing life-threatening electric shocks and minimizing the risk of electrical fires.
Versatile Application (Type A): Suitable for applications with both pure sinusoidal AC residual currents and pulsating DC residual currents, covering most standard domestic and commercial installations.
High Reliability: Siemens' quality engineering guarantees long-term stable operation and precise tripping characteristics, reducing false trips.
Space-Saving Design: Optimized dimensions for easy installation within distribution boards and compliance with industry standards.
Complete System Integration: Part of the comprehensive Siemens SENTRON modular protection devices, ensuring compatibility and ease of maintenance.
