Plug-and-Play Simplicity Allows Quick Motor and Equipment Changeouts

Equipment downtime can impact the productivity throughout a facility. MELTRIC Switch-Rated plugs and receptacles can eliminate lengthy downtimes associated with motor disconnections and replacements. The plug-and-play simplicity of a MELTRIC Switch-Rated connector can reduce motor changeout downtime by as much as 50%.

Pre-wire motors and equipment with MELTRIC Switch-Rated inlets or plugs to make changeouts fast and easy: 

  • No waiting for an electrician to perform field wiring
  • No "suiting up" with PPE or taking extraordinary electrical safety precautions required
  • No need to field test (jog the motor) to ensure proper rotation

Motor Plugs & Receptacles Benefits

Safe

Safe Operation

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.

Easy "Line-of-Sight" Operation

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 listed 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 mounted on walls, panels, equipment, or directly on the motor. This flexibility makes it simple to locate disconnects where they are easily visible and convenient to use.

Pre-Wire Replacement Motors

Pre-Wire Replacement Motors

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.

Auxiliary Contacts Monitor Motor Conditions

Auxiliary Contacts Monitor Motor Conditions

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 motor failure occurs.
