Residual Current Detection Type AC Sensitivity 30mA Sensitivity 2-Pole Configuration For 5SY Series MCBs Standard Protection

Product description

The Siemens 5SM2322-0 is a 2-pole residual current (RC) unit designed to be used with Siemens 5SY miniature circuit breakers, creating a residual current device (RCD) or RCBO. This unit features Type AC sensitivity, suitable for detecting sinusoidal AC residual currents. It has a rated current of 40A, a residual operating current of 30mA, and operates at 230V AC, providing standard protection against electric shock and fire hazards.

This RC unit is suitable for general applications in residential, commercial, and light industrial settings where Type AC sensitivity is adequate. It is used to equip a 5SY miniature circuit breaker with residual current protection, ensuring safety for circuits with standard loads.

Stanlo Automation, a veteran-owned distributor specializing in industrial surplus, offers the Siemens 5SM2322-0. We are committed to providing quality, reliable components and swift service to minimize your operational downtime.

Frequently asked questions

What type of fault currents does the Siemens 5SM2322-0 RC unit detect?

The Siemens 5SM2322-0 RC unit is a Type AC device, meaning it is designed to detect sinusoidal alternating current (AC) residual currents. It will trip when it detects an AC leakage current to earth, providing protection against electric shock and fire hazards caused by these types of faults.
