Applications:

Circuit breakers UKM30 series (hereinafter referred to as-the breaker) are for protection against overload and short circuit in the circuit of 50HZ, reted voltage 660V, it also can be used for non-frequent on-and-off switching operation ( uo to 30 times per day) under normal circumstance.

The breakers are meets requirement of IEC / EN 60947-2.

Technical data:

*"0"arcing distance: please specify when ordering if you require.

The product shall be operated under the following environmental conditions:

● Non-explosive;

● Does not contain corrosive gases and vapors in concentrations destroying metals and insulation;

● Not rich conductive dust and vapors;

● Lack of direct exposure to ultraviolet radiation;

● Should not be signifinant shock or vibration.

Transport ans storage are only permitted in the original packing.

The ambient storage temperature:-45...+60° C and humidity not above80% (at 25° C without condensation).

Installation and operating

The electrical work shall be performed by qualified personnel.

Before performing wiring work, turn off the upstream circuit breaker and ensure that no curren is flowing through the breaker to be wired.

Failure to do so may expose you to shock hazard.

When connecting any wire ,tighten the terminal screw to the torque specified in this manual. Failure to do so may cause a fire.

Do not install the breaker in an abnormal environment. Protect the circuit breaker so that the foreign particles,such as dust,concrete or/and iron power, water and other moistures will not enter the breaker. Failture to do so may make the breaker inoperative. Connect the circuit breaker to power supply appropriate to the rating voltage. Failure to do so may make the breaker inoperative or damage it. The breaker is installed in a plastic or metal box on a mounting plate with latches having two fixed positions. Power can be supplied from both the upper and lower contacrts.Terminals allow to connect copper or aluminum conductors.Before connecting standed conductors, they must be tipped using an appropriate tool.
