The breaker introduces the three-phase porcelain-pole with single interrupter structure. A spring operating mechanism is supplied and the mechanical action of the three-phase is inner connected. The gas of the SF6 is connected in the three-phase pole parts. A density controller with temperature compensation is used to monitor the gas of the SF6. Because of the self-extinction arc control principle and optimized design, it improves the efficient of mechanism and reduces the operating power.

Excellent breaking performance and long electrical life.

The metal frame and the support of the circuit breaker are bended with a whole deep steel plate. The hot galvanizing is used for the surface treatments. The high strength stainless steel and aluminum are used for the fasteners and the three-phase transmission shaft respectively, The surface of structure box is made by stainless steel the corrosion resistance of the mechanism is improved efficiently. High mechanism reliability and can be operated frequently. Because of the high insulation intensity and excellent contact movement, the breaking capacity current will not re-burn. The circuit breaker has high outer insulation level and ratio creepage distance is greater than 31 mm/kV. So it has excellent performance of resisting the filth and the earthquake it is also can be operated safely under the environment with atrocious weather. High carrying ability: it has high capability margin as the temperature of each contact rises when it is under temperature rise test in the circuit of 3780A (1.2 times of3150A).The appearance of the breaker is compact, and the installation and debugging is very easy. The maintenance is also very convenient.

2. Relative humidity : <95%.(3) During the transport, please handle the product gently, and do not upside it down, and prevent the product from harsh collision.

Maintenance

Carry out regular maintenance and remove the dust deposited on the thermal overload relay in time The thermal overload relay should be tested regularly to ensure that its action mechanism is flexible and the normally open and normally closed contacts are in good contact Terminal screw torque: Auxiliary contact: 1.2N.m

Main circuit: JRS1Ds-25:1.7 N.m
IRS1Ds-36:1.7 N.m
