Lifting Magnet Disconnect Switch - Type 4310

General

The 4310 fused magnet safety disconnect switch is designed to safely allow the operator of a lifting magnet to disconnect the highly inductive magnet while the magnet is still energized. Standard safety switches are not designed to safely disconnect an energized magnet.

The 4310 has (3) power poles. Two normally open power poles to disconnect the incoming power and a third normally closed power pole that shunts the magnets energy into a discharge resistor when the disconnect is switched to the off position.
