LY1-2 automatic reset

The LY1 series automatic 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
Normal working conditions
The ambient air temperature is -5 ℃~+40 ℃, and the average temperature within 24 hours should not exceed+35 ℃ (if the temperature is below -5 ℃, it should be stated when ordering above+40 ℃).
The elevation of the installation site shall not exceed 2000m.
The relative humidity of the installation site should not exceed 50% at+40 ℃. When the temperature is low, the relative humidity can increase (for example, it can be 90% at 20 ℃), and condensation that may occur due to temperature changes should be considered.
Places without significant shaking and shock vibrations.
