SR6118E Overload Relays Four Pole
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.
