MOTOR PLUGS & RECEPTACLES
Plug & Play Simplicity Allows Quick Change-outs
Equipment downtime can impact the productivity throughout a facility. When it comes to maintenance, hard-wired motors can cause longer than necessary downtime when a motor change-out is required. MELTRIC Switch-Rated plugs and receptacles can eliminate lengthy downtimes associated with disconnecting the field wiring of hard-wired motors. They feature plug & play simplicity, which can help reduce motor change-out downtime by as much as 50%. When replacement motors are pre-wired with Switch-Rated inlets or plugs, a mechanic can safely change-out a motor by simply unplugging the old motor and re-plugging in a new one. No tools or materials are required.
- No waiting for an electrician to perform field wiring
- No "suiting up" or taking extraordinary electrical safety precautions is required.
- No need to field test (jog the motor) to ensure proper rotation
Safely Make/Break Motor Connections, Even During Overloads
MELTRIC Switch-Rated plugs and receptacles are designed and rated to make and break motor loads in complete safety while providing users with significant protection in the event of overloads or short circuits. Operators do not require special protective equipment or training to make and break connections with MELTRIC Switch-Rated devices.
- Overload testing includes 50 opening and closing operations performed at 600% of full load motor ampacity with a power factor of 0.5 or less.
- All hp-rated Switch-Rated devices are rated to close into and withstand short circuit currents up to 100kA in circuits protected with RK1 fusing.
Note: Although MELTRIC Switch-Rated plugs and receptacles are rated to safely
make and break motor loads, they are not rated or intended for
continuous use as a motor starter.
Easily Locate "Line of Sight" Disconnects Using Mounting Options
Sections 430.102 – 430.109 of the National Electric Code require approved disconnecting means to be located in a readily accessible location within sight of the motor and driven equipment. Since MELTRIC Switch-Rated devices are UL & CSA rated for "Motor Circuit Disconnect Switching" and "Branch Circuit Disconnect Switching,' they are an approved 'line of sight' disconnect switch. They are a simple and convenient way to meet this NEC requirement.
MELTRIC Switch-Rated plugs and receptacles are available with numerous handles, mounting angles, wall boxes, and other accessories. They may be used as in-line connectors or may be mounted on walls, panels, equipment, or even directly on the motor. This flexibility makes it simple to locate disconnects where they are easily visible and convenient to use.
Reduce Improper Motor Rotation with Pre-wired Replacements
Replacement motors that are pre-wired and tested with appropriately phased receptacles in the service center will automatically provide the desired direction of rotation when connected (plugged in) on site. Pre-wiring and testing eliminates the need to jog the motor and avoids additional downtime and production problems resulting from improper rotation.
Monitor Motor Temperature Using Built-in Auxiliary Contacts
Optional integral auxiliary contacts can be used to communicate motor temperatures back to a control center so preventative maintenance can be performed before a motor failure occurs.
