Jet pm1800b-043a Magnetic Switch 5HP 230V 1ph

Product Description

The JET pm1800b-043a is a magnetic switch designed as a replacement part for JET power tool applications requiring reliable motor switching in single-phase electrical systems. Rated for 5 horsepower at 230 volts, this switch provides the electromagnetic contactor function that controls motor start and stop operations. It is a direct-service component installed by qualified electricians or power equipment technicians performing maintenance or repair on JET machinery. The magnetic switch uses a solenoid-actuated contact assembly to engage and disengage motor circuits under load, providing consistent switching performance in shop and industrial environments.

This switch is suited for single-phase, 230-volt motor circuits rated up to 5 horsepower, typical of table saws, band saws, jointers, planers, and similar stationary power equipment. It is a factory replacement part sourced directly from JET, making it appropriate for technicians restoring OEM electrical function to affected machines. Installation is performed when the original magnetic switch exhibits contact wear, coil failure, or failure to engage or release under normal operating conditions.

Key Features

• Rated for 5 horsepower single-phase motor circuits
• Operates on 230-volt single-phase power supply
• Electromagnetic switching action for reliable motor start and stop control
• OEM replacement part for JET power tool equipment
• Designed to restore factory electrical switching function

Compatibility

Designed as an OEM replacement magnetic switch for JET power tools and machinery equipped with 5 HP, 230-volt single-phase motor circuits.

Installation Notes

Installation should be performed by a qualified electrician or trained power equipment technician. Disconnect and lock out all power to the machine before removing or installing the magnetic switch, following NFPA 70E lockout and tagout procedures. Verify that the replacement switch ratings match the existing circuit voltage, phase, and horsepower requirements before energizing. Do not bypass or jumper the switch contacts during testing.
