SMR22 16-22A

SMR

Characteristics

SMR- □□ type thermal overload relay is mainly used in the electric system with AC 50Hz-60Hz, rated operation voltage up to 660V,current to 800A. It is used to protect AC three-phase asynchronous motor against overload and open-phase. This products can be properly combined with contactors and installed in an enclosure as motor starter to protect the motor from overload and open phase.

Type and Signification:


Characteristics:

● When the thermal overload relay tripped, the trip indicator will go up 2-3mm;When the thermal overload relay on the mode of manual reset ,you can put on the reset button to reset.

 Automatic reset:put on the reset button and turn 90°anticlockwise.

 Main circuit terminal and control circuit terminal is clearly distinguished to avoid wrong wiring by manual.
