Current Sensing Switch

Aldes Current Sensing Switch senses when a clothes-drying device is drawing between 1 and 50 Amps of current. When this occurs, a relay contact closes, turning on the fan. When current drops below the threshold, the relay contacts open, turning off the fan.

The sensor is rated to control a load of 2.5 Amps at 115 V. For higher amperage loads, a general purpose relay may be used to control the load. The sensor is designed to mount in a standard electrical box. The current transformer may be placed in an electrical box adjacent to the junction box with the wires supplying power to the device. The device supply neutral (white) wire passes through the center of the current relay donut. No physical connection needs be made.

NOTE: Installation by a licensed electrician is recommended. Installation and use of this equipment must be in accordance with provisions of the national electrical code. Applicable local codes and pertinent industry standards should be verified before installation.

Electrical Ratings: 120 V, 60 Hz, 2.5 A.
