Combined overcurrent and residual current protection 6 kA breaking capacity Type AC RCD sensitivity C-characteristic tripping curve Compact 1P+N design

Product description

The Siemens 5SU1356-1KK13 is a compact Residual Current Breaker with Overcurrent protection (RCBO) offering essential safety features for electrical circuits. It has a breaking capacity of 6 kA, a 1-pole plus neutral configuration, and Type AC RCD sensitivity, which primarily detects sinusoidal AC residual currents. This device features a 30 mA leakage current threshold, a C-characteristic tripping curve, a rated current (In) of 13 A, and operates at 230 V AC.

This RCBO is suitable for general-purpose protection in residential and commercial installations where the primary concern is protection against AC earth fault currents and overcurrents. The C-characteristic curve provides reliable protection for circuits with moderate inrush currents. It is designed for use in countries adhering to relevant national installation regulations.

As a veteran-owned surplus distributor, Stanlo Automation provides access to reliable components like the Siemens 5SU1356-1KK13. We ensure that industrial automation professionals can obtain quality surplus parts, minimizing downtime and project delays.

Frequently asked questions

What is the advantage of the C-characteristic on the Siemens 5SU1356-1KK13 RCBO?

The C-characteristic tripping curve on the Siemens 5SU1356-1KK13 allows for a higher inrush current before tripping compared to a B-characteristic. This makes it suitable for circuits with moderate inductive loads, such as lighting or socket outlets, where brief current surges are normal.
