LY1-1 manual reset

The LY1 series manual reset is suitable for auxiliary circuits with AC 50Hz, AC380V, and DC220V. It limits the maximum speed of the motor and can quickly break the circuit to ensure safe operation. Mainly used in the lowering overspeed protection circuit of the crane lifting mechanism, it can also be used in similar situations that require overspeed protection.
Model Meaning
