24V and 120V
GA50 and GA51 Current Sensing Relay

Designed to interface with humidifiers and most heating and cooling systems
It senses current rather than measuring voltage, making it more reliable. It is less expensive than using traditiional flow switches, pressure switches or other types of relays. The relay installs around the blower motor`s common lead and interface easily into the circuitry.

The current sensing relay case is constructed from high impact plastic. The lead wire bracket is protected by a soft sponge insert, in order to prevent damage to the motor/blower wire and /or accidental contact with any metal.
