LOAD BREAK SWITCH (LBS)
A load break switch, also known as a disconnector switch or isolator switch, is an electrical switch designed to interrupt the flow of electrical current in a circuit when it needs to be de-energized for maintenance, repairs, or isolation. It is commonly used in electrical distribution systems.
RPS feature
The high quality 3 mm stainless steel are used for tank, which is designed for its maximum robustness and minimum welding line to minimize corrosion, and specifically to guarantee the safety of the operation personnel even with the internal arc faults at the maximum fault capacity of the tank the RPS can withstands an internal fault without venting hot gases. The independent spring operation mechanism adopt ROCKWILL® patent spiral spring, provides a guaranteed load break fault make capability by ensuring the opening and closing speed of the switch.
The RPS is provided with light reflecting position indicator which are directly connected to the switch operating shaft providing clear and unambiguous switch position indication. Indicator made of light reflecting material, which is easily visible from ground level even at night in driving rain.
