Hubbell Industrial
Speed Switch Series 2200 - Type PR

Description

Machine Tools -- Euclid Type PR Series can be used to increase production as a zero-speed plugging switch with normally open contacts incorporated with a magnetic reverse panel to bring AC motors to a quick stop.

Motion Interlocking -- such as on conveyor systems, where a centrifugal switch is driven by the main conveyor at a location near the junction with a feeder conveyor.  The normally open centrifugal switch contacts are connected in series with the control circuits of the magnetic controllers for the motors driving the feeder conveyors.  If the main conveyor accidentally stops, the centrifugal switch driven by that conveyor will automatically stop the motors driving the feeder conveyors, preventing material from being piled up on the stalled conveyor by the feeder conveyors
