Description
The United Electric H100-524 pressure switch is a low-pressure, field-adjustable control designed for precise monitoring of air and gas systems in HVAC and industrial applications. With an adjustable setpoint range of 2.5 to 50 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 4X-rated enclosure, the H100-524 offers protection against water, dust, and corrosion, making it suitable for harsh or washdown environments. This model features automatic reset operation for continuous system control.
