Supplementary Protectors

Supplementary Protectors

Supplementary protectors can used in a number of industrial applications allowing the user to quickly find the problem circuit should a fault occur without having to shut down all of the other control circuits. Supplementary protectors may also be used as a local disconnecting means inside the panel when a branch circuit protection device is already present.
