The Anatomy of an Interrupter Switch
To gain a comprehensive understanding of an interrupter switch, it’s important to understand its individual components.
The Switch Handle
The switch handle, commonly referred to as a toggle, flips to the ‘on’ or ‘off’ position manually but will automatically move to the ‘off’ position when a fault is detected.
Switch Contacts
When the switch is in the ‘on’ position, electricity flows through the contacts. These contacts separate when the switch is flipped to the ‘off’ position or if a fault is detected, stopping the flow of electricity.
Current Sensing Unit
The current sensing unit keeps a continuous watch on the flow of electricity. If a surge or drop in current is detected, this unit triggers the contacts to separate.
Tripping Unit
The tripping unit is the component that actually causes the contacts to separate in the event of an electrical problem.
