Description

This post is also available in: thไทย (Thai)

Type-tested parameters:

  • Transfer Current: up to 1,700 A
  • Electrical endurance: 2,000 times
  • 12kV Panel dimensions as compact as 400 x 1,700 x 800 (WxHxD)

The ALBS load break switch is designed for 12kV – 24kV applications. Mounted in a switchboard enclosure, the ALBS is suitable for indoor or outdoor applications depending on the construction of the switchboard.

The ALBS is capable of higher performance. At the same time it is compactly designed using lighter and stronger engineering materials, making it an altogether smaller product.

The ALBS is a three phase air pneumetic load break which uses compressed air as an arc quenching medium.

The spring-charged driving mechanism of the switch is located at the front of the switch for ease of access during service. The ALBS’s reduced dimensions implie that it can be housed in smaller enclosures with air being the insulating medium.

The compact and modular structure of the ALBS series load break switch and the LCA-A switchboard enables space-saving use for a wide variety of power distribution applications.
