Applicable Scope

COB series is suitable for using in the circuit that frequency 50/60Hz, rated voltage up to AC380V or DC250V. It is mainly used outdoor, and could be used in snowy, dusty environment, for the remote controlling of the crane, hoist and other equipments.

Working And Mounting Condition

1. Ambient temperature: -5?~+40?, average temperature≤+35? in 24h
2. Altitude≤2000m
3. Air condition: when temperature up to 40?, the humidity should be ≤ 50%, temperature lower, the humidity higher, for example, humidity would be 90% when temperature is +20?. Occasionally, due to temperature changes resulting condensation, special measures should be taken.
4. Pollution degree :
5. Mounting type: Type II
6. No significant shake, shock and vibration
7. In the absence of explosive medium, the medium does not enough to corrode metal and damage the insulation.
