5SU1356-1KV06

The Siemens 5SU1356-1KV06 is a Residual Current Circuit Breaker with Overcurrent protection (RCBO) from the 5SU1 series, designed for integration into low-voltage distribution systems where combined protection against earth faults, overload, and short-circuit conditions is required. The 5SU1 series is widely deployed in residential, commercial, and light industrial applications, recognized for its compact design, robust performance, and compliance with international standards. These RCBOs are commonly used in modern distribution boards to ensure personnel and fire protection, as well as equipment safety.

The 5SU1356-1KV06 features 1+N, a rated current of 6A, a breaking capacity of 10kA@400V, and a C-type tripping characteristic, making it suitable for circuits with moderate inrush currents such as inductive loads. The device operates at 400V AC, with a rated residual current of 30mA (type AC), and is designed for DIN rail mounting. It provides IP20 protection when installed, supports a wide ambient temperature range (-25°C to +55°C), and accommodates conductor cross-sections from 0.75 mm² to 35 mm². Additional features include neutral conductor switching, touch protection, halogen-free and silicon-free construction, and a compact footprint of 90 x 36 x 77 mm.
