Monitoring relays


Monitoring relays - Protection for every plant

Thermal and electronic overload relays are used for current-dependent overload protection in the main circuit, and thus for the protection of any kind of machines and installations. Monitoring relays act as apparent/active current monitoring. They detect current that is too high and too low, mains and voltage errors, wire break, and phase failure in the whole installation. Electrical relays ensure a reduction of the power loss by up to 98 % as compared to thermal overload relays.

Use of current monitoring relays

Monitoring relays are used in all areas of electrical switchgear technology. The main tasks are:

  • Machine and plant protection
  • Motor protection

The monitoring relays can be easily mounted - thanks to the matching size and user-friendly screw connection - and integrated into the system. Their compact design ensures there is more space in the control cabinet.

 

Different monitoring relays available

Automation24 carries electrical monitoring and protection relays from the premier manufacturer Selec. They monitor several crucial functions, with adjustable thresholds, and a number of operating ranges, available both with digital displays, such as the 900VPR-2-280/520V-CU, and simple dial settings, as with the 600VPR-170/290-CU.

At Automation24, we offer a large selection of monitoring relays at very favorable prices. Select the monitoring relay suitable for your application now!
