JRS4-140d series thermal overload relay is mainly used for AC 50Hz (or 60Hz), rated insulation voltage 690V, rated working voltage to 660V, rated current up to 140A circuit, and GSC1-115 to 170 contactors with for exchange Motor overload and phase failure protection. 
 The GSR1 series of electronic overload relay (hereinafter referred to as overload relays) for exchange 50Hz/60 Hz, rated voltage to 660V, rated current up to 95A of the circuit for three-phase AC motor overload, broken and three-phase The unbalance protection, AC contactor motor starter. 
 A variety of protection functions 

 △ overload: the inverse-time characteristic curve of action (see photo); 

 △-phase protection: motor with the load operation, phase failure tripping 4 seconds; 

 △ stall protection: According to the inverse-time characteristics of the action; 

 The △ phase unbalance protection: the phase imbalance was more than 35% within four seconds of action; 

 △ thermal memory function: able to simulate the memory of the motor heat accumulation, the motor starts running, overload and breaking continuous fever cumulative memory. Repetitive overload protection, but also simulates the motor thermal transpiration. 

 GSC2-J Building AC contactor is mainly used for household and similar purposes, used for the main circuit of AC 50Hz (or 60Hz), rated insulation voltage 440V, rated working voltage up to 415V, use the category AC-7a under rated operating current to 63A, utilization category AC-7b under rated operating current 30A, rated limit short-circuit current is less than or equal to 6KA the circuit for the construction of buildings in the making and breaking circuit, in particular, switching and control lighting, heating, ventilation, pumps, heat pumps and other equipment.
