Description
The United Electric J400K-455 pressure switch is a low-pressure control designed for precise monitoring of air and gas systems in HVAC and industrial applications. With an adjustable setpoint range of 5 to 80 inches of water column (in. W.C.), this switch is ideal for applications such as airflow proving, duct pressure monitoring, and filter status indication. The SPDT (single-pole, double-throw) contact configuration provides flexible control for both normally open and normally closed circuits. Housed in a NEMA 4-rated enclosure, the J400K-455 offers protection against water and dust, making it suitable for demanding indoor and outdoor environments.
