Load Break Switch (LBS)

Call for Price

A load break switch (LBS) is a device that controls the flow of electrical current in a circuit, allowing for the safe disconnection and reconnection of power lines. It’s similar to a light switch in your home, and can be used to turn power on or off, or change its position when the transformer is energized. LBSs are a key component in many applications, including distribution substations, ring main units, and overhead or underground systems. 

LBSs have several advantages over 2 pole structures, including:
  • Safety: LBSs ensure the safety of operators during the life cycle of a low-voltage electrical facility
  • Cost: LBSs are generally cheaper than 2 pole structures
  • Ease of use: LBSs are easy to turn on and off
  • Transformer protection: LBSs can protect transformers 
LBSs can switch voltages from 1000 volts to 33 kilo volts, and come in different types, including universal, photovoltaic, and air load break switches. They can also be equipped with optional components, such as voltage sensors.
