Thermal Overload Relay

Thermal Overload Relays are designed for circuit surge current and short circuit protection in terms of preventing damage. Versatile functions provide manual and auto reset functions, overload protection and phase failure protection. Stable and sharp tripping functions provide you with wilder application choice.
Features and Functions of Thermal Overload Relays
Protect high/low reactance system, such as motor, compressor, fans and etc.
Phase short circuit/phase failure
Overload curve optional
Lock-rotor protection
Instantaneous Ground fault protection
Working Environment Restrictions
Elevation < 20MRelative Humidity 45～85%RH
Ambient temperature constraint: -40℃～65℃ (Freeze Prohibited)
Coil current is restricted between 80%～105% of rated current
Application of Thermal Relay:
The thermal Relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-96A for protection the phase break when the electric motor is overload. The relay has different mechanism and temperature compensation. It is the most advanced thermal relay in the world.
