SR6118E Overload Relays Four Pole Electrical Training Equipment Vocational Training Equipment Didactic Equipment Teaching Equipment
I.Working principle and usage
The thermal element of the thermal overload relay is directly or through the current transformer connected to the motor circuit. When the motor is overloaded, the main bimetallic strip is heated to the action temperature, which makes the relay move, and the power circuit of the power failure motor is divided, so that the motor is not damaged by overload. Thermal overload relay action time and the relation of the size of the overload current according to the inverse time, therefore, its thermal characteristic is easy to cooperate with the thermal characteristics of the motor, but also has simple structure, low price, stable performance, convenient use, etc. Therefore, in the 1990s, most squirrel cage rotor motors and partial winding rotor motors still used thermal overload relay as protection of overload, break phase and current imbalance operation. Thermal overload relay can also be used for other electrical equipment to control the heating status of electrical appliances.
II.Technical data
Overload relay (4 - pole 53A & 85A)
Maximum voltage: 600V AC,240VDC.
III.Application range
Thermal overload relay of the scope of application: thermal overload relay for ac 50 hz, rated insulation voltage 660 v, current 0.1 ~ 630 a circuit, it is mainly used for three-phase ac motor overload and phase failure protection. It can also form a starter with an adaptive ac contactor, such as an overview of the diagram thermal relay configuration
