4.5 kA breaking capacity 1-pole + neutral configuration Type AC residual current detection 30 mA sensitivity C-curve tripping Suitable for circuits with moderate inrush currents

Product description

The Siemens 5SU1353-1KK16 is a 1-pole plus neutral Residual Current Circuit Breaker with Overcurrent protection (RCBO). It offers a 4.5 kA breaking capacity, is a Type AC device for detecting sinusoidal AC fault currents, and has a 30 mA residual current rating. It utilizes a C-curve tripping characteristic and is rated for 16A at 230V AC.

This RCBO provides protection against overloads, short circuits, and AC earth leakage currents. It is important to note that Type AC RCDs are subject to national installation regulations and may not be permitted in all countries or applications due to their limited detection capabilities compared to Type A or B devices.

Stanlo Automation, a veteran-owned surplus parts distributor, is committed to supplying quality industrial automation components. Purchase the Siemens 5SU1353-1KK16 from us to benefit from reliable products and exceptional service.

Frequently asked questions

What are the limitations of Type AC RCBOs like the Siemens 5SU1353-1KK16?

Type AC RCBOs, such as the Siemens 5SU1353-1KK16, are designed to detect sinusoidal AC residual currents only. They may not detect pulsating DC or smooth DC residual currents, which can occur with some electronic equipment, and their use is restricted in certain countries or applications.
