| 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. |
