Description
F&F CR-810DUO – PTC resistive relay for thermal protection of motors and transformers
F&F CR-810DUO is a resistive relay designed for the thermal protection of electric motors, transformers and other equipment exposed to overheating. It works with PTC sensors – up to 6 sensors can be connected simultaneously, enabling multi-point temperature monitoring within a single circuit.
The device responds to a rapid increase in the resistance of the PTC sensor, which occurs when the permissible temperature of the protected components is exceeded. Relay activation is signalled by a red LED, and the 1NO/NC output contact allows the load to be switched off directly or an alarm signal to be sent to the controller.
The relay has a universal power supply – 24 V DC or 230 V AC – allowing it to be used both in low-voltage control circuits and in standard industrial switchboards. Its 1-module housing designed for DIN rail mounting ensures compact installation in control cabinets and electrical switchboards.
Applications
- Thermal protection of electric motors and pumps
- Protection of transformers against winding overheating
- Temperature monitoring in control cabinets and switchboards
- Thermal protection of industrial equipment with PTC sensors
