What is a disconnect switch with visible disconnection?
A visible-break disconnector is a type of disconnector that allows you to physically see whether the electrical installation is live or not. It is often used in situations where the safety of people and equipment is critical.
When should a disconnect switch with visible disconnection be used?
Here are some of the situations in which it is preferable to use a disconnector with visible disconnection:
- Places with a high risk of fire, such as factories and industrial buildings
- In critical applications, such as hospitals, power stations and airports
- In security installations, such as alarm systems and fire safety systems
- On installations with a high maintenance and repair rate, visible disconnect switches can be used to cut off the power supply to a specific piece of equipment or area.
Generally speaking, the electrical standard in force will specify whether the use of a visible disconnect switch is mandatory.
