MURPHY VS2EXR-24 EXPLOSION-PROOF VIBRATION SWITCH PART NO 2070005

The VS2EXR-24 switch is a shock sensitive mechanism for shutdown of engine or electric motor-powered equipment. This switch uses a magnetic latch to ensure reliable operation.

This model features a 24 VDC remote reset coil.

The VS2EXR-24 has a base mounted case, explosion-proof aluminum alloy housing; meets NEMA 7/IP50 specifications; Class I, Division I, Groups C & D; UL and CSA listed with 480 VAC rating. In place of the leaf-type contacts, 2-SPDT snap-switches are used in this model. Sensitivity is externally adjustable and, when tripped, the VS2EXR-24 gives a Tattletale indication on the reset button.

Ideal for use on engines, pumps, compressors, heat exchangers and pumping units - the VS2EX can be used anywhere shutdown protection from damaging shock/vibration is desired. Switches are field adjustable to sensitivity required in each application. MurCal can provide a certificate of conformance for the VS2EX-24, but no calibration report is available.

There is no calibration report for the VS2EX-24.

Basic Operation:
 
Pushing the reset button moves the tripping latch into a magnetically held position. A shock/vibration will move the magnet beyond this holding position, thus freeing the spring-loaded tripping latch to transfer the contacts and shut down the machinery (see dimensional diagrams or visual representation of parts).
