TECO-Westinghouse RHN-80A4 Relay

The TECO-Westinghouse RHN-80A4 Relay provides electromagnetic switching and isolation of control circuits in industrial motor control and automation systems. This plug-in industrial relay features a 4-pole changeover (4PDT) contact configuration with a rated current of 5 A and is coil-operated for reliable control of contactors, starters, alarms, timers, and interlocking circuits. It uses a plug-in socket mount and silver alloy contact material (configuration dependent), with a dielectric-strength insulation between coil and contacts for robust performance in industrial environments. Mechanical life is up to 20 million operations (relay series dependent) and electrical life supports high-cycle industrial duty, while operating temperature is suitable for typical industrial control panel environments. The RHN-80A4 is compatible with motor starters, PLC control panels, HVAC systems, conveyors, pumps, compressors, and other industrial automation equipment, making it suitable for control logic, signal isolation, interlocking circuits, alarm systems, and auxiliary control functions. Maintenance teams and system integrators use this part for repair, retrofit, expansion, or replacement of industrial control and relay systems. Common replacements include Schneider Electric RHN412BA76, Omron MY4N Series Relay, and IDEC RU4 Series Relay.
