Description
The United Electric H400K-455 pressure switch is a versatile, field-adjustable control designed for low to mid-range pressure applications in HVAC, pneumatic, and industrial systems. With an adjustable setpoint range of 5 to 80 PSI, this switch provides reliable pressure monitoring and control for system cycling, alarms, and safety functions. The SPDT (single-pole, double-throw) configuration supports flexible wiring for normally open and normally closed circuits. Featuring a multi-output design, the switch can support multiple control functions within a single device. The NEMA 4X-rated enclosure offers enhanced protection against water, dust, and corrosion, making it suitable for harsh or washdown environments.
