63A Electrical Isolator Switch PA66 IEC60947.3 1P 2P 3P 4P Main Switch Din Rail Mounting

STIS4-63 Series 63A isolator switch PA66 IEC60947.3 1P 2P 3P 4P Din Rail mounting main switch

Basic Information

STIS4-63 main switch has the features of structure advanced, performance reliable , appearance elegant and its shell and parts are made of material with impact resistance, strong flame-retardant feature.

It is suitable to power system of 50or 60 frequency ,Ue 400V and below, Ui 63A and below.

It is mainly applied at office building, residence, for lighting , power distribution and turn on/off . Normally, it also can be used as the not frequent transfer of power system. It conforms to the standards IEC60947.3.

Main Functions

• Protection against overload – currents above the rated value that last longer than what is normal for the application.
• Protection against electrical faults – During a fault such as a short circuit or line fault, there are extremely high currents that must be interrupted immediately.
• Switching a circuit on and off – This is a less common function of circuit breakers, but they can be used for that purpose if there isn’t an adequate manual switch.
