PSSR

The Power Solid-State Relays enable wear-free, reliable and silent switching of high AC loads up to 75 A. They also have a high degree of shock and vibration resistance for protection in the process industry.

 

Features

Simple current monitoring

The optional, plug-on monitoring module warns when current drops by 16 % or more. Short-circuit, line-break and defective loads are detected.

Simple current control

The 70 A phase control with analogue input (4 – 20 mA) allows you to set up a heating controls or the power control of single-phase motors.

Affordable conductor protection

The high current load integral I²t of 6,000 A²s allows the use of standard circuit breakers for variants with 35 A load current.

Direct mounting at the site of application

Ideal for controlling pipe trace heating due to the high output current of 50 or 75 A. The compact design allows direct mounting at the site of application.
