Siemens SENTRON 5SU1346-6FP16 RCBO 4P B16 6kA Type-A 30mA 4TE

The Siemens SENTRON 5SU1346-6FP16 is a high-quality Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed for reliable protection of electrical installations. This 4-pole device combines overcurrent and residual current protection in a single compact unit, saving space in distribution boards. With a rated current of 16 A and a B tripping characteristic, it is ideal for protecting circuits with resistive and inductive loads. The Type A residual current detection ensures sensitivity to pulsating DC fault currents, making it suitable for modern electronic equipment.

Advantages

Combined overcurrent and residual current protection in one device reduces installation time and panel space. The 6 kA short-circuit breaking capacity provides robust protection against high fault currents. The compact 4TE (72 mm) width allows for efficient use of DIN rail space. Screw terminals ensure secure and reliable connections for solid and stranded conductors up to 25 mm².

Suitable for

• Residential and commercial distribution boards
• Circuits requiring both overcurrent and residual current protection
• Applications with electronic loads such as computers, chargers, and LED lighting
• Protection against sinusoidal AC and pulsating DC residual currents
