Application |
They have a residual current operated electromechanical release which operates without any auxiliary source of supply to open a circuit automatically in the case of an earth leakage fault between phase and earth greater than or equal to a threshold of 10mA,30mA,100mA,300mA or 500mA. |
Specification: |
1.Series 5SM1 Leakage Breakers are the protector for pure electromagnetic residual current operation. 2.The operation function is unrelated to circuit voltage,but operation is reliable. 3.It can be reliably operated on the loss of phase or neutral. 4.The capacity of resisting electromagnetic interference is strong. |
