Multiquip CA302LN Switch 3 Phase MP2/MS2 - OEM Replacement Part

This three-phase electrical switch controls power distribution to the motor and integrated water delivery system on MP2 and TRAK20 series masonry saws. As a critical safety component, it manages the operation of both the cutting head motor and the electric submersible water pump required for OSHA 2017 compliance governing occupational exposure to respirable crystalline silica. All sawing operations must be conducted with an integrated water delivery system, making this switch essential for legal and safe operation.

The switch interfaces with the AC receptacle on the electric motor conduit box, coordinating power to the blade drive system and the water pump that must remain immersed during operation. Failure symptoms include inability to start the motor, loss of water pump function, or intermittent power delivery that can compromise both cutting accuracy and dust suppression. Regular inspection of electrical components is recommended as part of routine maintenance to ensure proper alignment of the jackshaft and blade shaft systems.

Compatible with the following Multiquip models:

• MP2-SERIES Masonry Saws
• TRAK20-SERIES Masonry Saws
