General Filters ga50 Current Sensing Relay 24V

Product Description

The General Filters ga50 is a 24-volt current sensing relay designed for use in HVAC control circuits. Current sensing relays detect the presence of current flow in a monitored circuit and trigger a secondary output, allowing the system to coordinate the operation of multiple components. The ga50 operates at 24 volts, making it compatible with standard low-voltage HVAC control wiring found in residential and light commercial systems. Licensed HVAC technicians install this relay as part of zone control, humidity control, or accessory coordination applications.

The ga50 is suited for residential and light commercial HVAC installations where a secondary device must be activated in response to current draw from a primary component. Common applications include activating whole-home humidifiers, electronic air cleaners, or other 24-volt accessories when the air handler or furnace blower motor energizes. This type of relay eliminates the need for direct wiring between the primary component and the accessory, simplifying installation and reducing control board load.

Key Features

• 24-volt operating voltage for compatibility with standard low-voltage HVAC control circuits
• Current sensing design triggers secondary output based on detected current flow in monitored line
• Suitable for coordinating accessories such as humidifiers and electronic air cleaners with blower operation
• Compact relay form factor for installation in air handler cabinets or equipment enclosures

Compatibility

Designed as an OEM-style replacement or upgrade relay for residential and light commercial HVAC systems requiring 24-volt current sensing relay functionality.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable local codes and manufacturer wiring diagrams. Disconnect and lock out power to the HVAC system before handling any control wiring or relay connections. Verify the monitored circuit current range is within the relay's sensing threshold before finalizing installation. Do not exceed the relay's rated voltage when connecting control circuit wiring.
