Mitsubishi TH-N Series Thermal Overload Relays
- TH-N Thermal Overload Relays - A Convenient and Safer System
The TH-N Series overload relay will protect a motor from burnouts caused by overload, locked rotor, or single phasing. A relay is a three pole, bi-metal, non-interchangeable heater element type (phase failure protection). Although designed as a three pase device, TH-N overload relays can be used to protect single phase motors by connecting two heaters in series to one motor leg, and connecting the thrid heater to the other motor leg.
- Maintenance and Inspection
An operation indicator makes maintenance and inspection easy. Checks can be performed using manual operations.
- Rated Current Can Be Set Easily
The rated current value is displayed on a dial. Simply adjust the dial to the full-load current of the motor to assure motor protection.
