Power Relays, Over 2 Amps

The 18732B200 Power Relay is an over 2 amp unit designed for use in industrial, manufacturing, and commercial applications. It has been designed for high-efficiency operation with low maintenance, and is engineered to meetUL 508A specifications for power protection, control, and monitoring.

Construction

The piece contains a light-weight molded plastic body and coil cover to provide strength and corrosion resistance. The coil type is designed for convenient installation and the power coil is provided with an insulated housing for safety against burns. The coil is rated for up to 1.5 amperes maximum and has a power factor of 1.0.

Operation

The relay utilizes a single-phase, insulated power coil to create an electromagnetic field. This field, when energized, attracts an armature, which in turn, actuates the normally open contacts. The armature is connected to a plastic bellows that seals off the interior of the relay from the outside environment to eliminate the possibility of corrosion.

The contacts are rated for energization up to 2 amperes and can be opened and closed using a toggle switch, pushbutton switch, or a motorized actuation switch. The relay is tested and operated with no-load voltage of 110-120 volts AC. The maximum switching capacity is 2,000 watts.

Features

The 18732B200 Relay enjoys the following primary features:

• K-Grade insulation for superior electrical performance
• Coil voltage rating of 110-120 volts AC
• Maximum switching capacity of 2,000 watts
• UL 508A approvals for power protection, control, and monitoring
• Self-adhesive coil cover for ease of installation
• Molded plastic body and components coated for corrosion resistance
• EMI/RFI shielding protection

Uses

The 18732B200 Power Relay is designed for use in industrial, manufacturing, and commercial applications. Applications include but are not limited to:

• Power control and switching
• Motor control
• Lighting control
• Heating and cooling systems
• Building security
• HVAC systems
• Fire and smoke control systems
• Safety systems
• Power distribution and monitoring

Installation

The 18732B200 power relay is designed for quick and easy installation. The unit should be mounted to a flat and level surface in a room or area that is free from moisture and dust. The unit requires an accessible power source and a suitable mounting plate to mount the device securely. Additionally, the unit requires wiring for the open contacts when it is switched.

The coil cover is easily marked with the color of the electromagnetic switch to help identify and troubleshoot the device when it is energized or de-energized. The body of the unit can be marked with tags or labels to indicate the purpose of the relay.

Maintenance

The unit should be inspected at least twice a year to ensure that it is in good working order and to prevent any potential hazards. If the unit is not working properly, it should be replaced immediately. Additionally, all electrical connections should be checked for proper conductivity before operation.

When the unit is not in use, it should be unplugged and the power supply should be switched off. This will prevent any potential hazards and ensure the optimal performance and reliability of the 18732B200 power relay.
