Type AC sensitivity 3-pole design 63A rated current 300mA tripping current 400V AC operational voltage For 5SY series

Product description

The Siemens 5SM2635-0 is a 3-pole Residual Current (RC) unit from the 5SY series, featuring Type AC sensitivity. It is rated for 63A (In), with a tripping current (IΔn) of 300mA, and operates at 400V AC. This unit provides supplementary protection for three-phase circuits against AC residual currents.

This 3-pole Type AC RC unit with a 300mA tripping current is designed for applications requiring supplementary protection against earth faults in three-phase systems, such as industrial machinery or distribution panels. It is suitable where adequate earthing is in place and fire protection is a primary concern.

As a veteran-owned supplier of surplus industrial automation parts, Stanlo Automation is your go-to source for components like the Siemens 5SM2635-0. We are committed to providing quality, reliable parts to ensure your industrial operations remain efficient and uninterrupted.
