United Electric H400-453 Pressure Switch
The United Electric H400-453 is a heavy-duty 0-20 PSI pressure switch from the 400 Series, engineered for precise threshold protection and multi-output control in demanding industrial environments. Designed with a NEMA 4X enclosure made of epoxy-coated diecast aluminum, this unit provides exceptional resistance to corrosion and moisture, making it ideal for pump, turbine, and compressor applications. It features a single SPDT switch output rated at 15A @ 125/250/480 VAC, allowing for versatile high-capacity electrical interlocking. Professionals rely on the H400-453 pressure switch for its internal adjustable setpoint range, which includes a reference dial and a tight deadband of 0.05 to 0.2 PSI for critical accuracy. With 3/4 inch FNPT electrical connections and dual 7/8 inch knockouts, integration into existing conduit systems is streamlined. This industrial pressure switch is field-proven for HVACR and process automation, ensuring reliable performance in safety and emergency shutdown circuits. Ensure process compatibility with the Buna-N diaphragm before final plumbing to the 1/4 inch NPTF connection.
Key Benefits- Rugged NEMA 4X Protection: The epoxy-coated aluminum housing stands up to harsh chemicals and outdoor exposure.
- Critical Setpoint Precision: Offers an adjustable 0-20 PSI range with a reference dial for repeatable accuracy in low-pressure monitoring.
- High Electrical Capacity: Equipped with a 15A SPDT snap-acting switch to handle heavy inductive loads without secondary relays.
- Simplified Installation: Features 3/4 inch FNPT conduit entry and a standard 1/4 inch NPT pressure port for rapid HVAC pressure switch replacement.
- Enhanced Durability: Provides a proof pressure rating of 225 PSI, protecting the sensor against system surges and spikes.
- What is the deadband for the H400-453? This model features a narrow deadband range of 0.05 to 0.2 PSI, ensuring sensitive response to minor pressure fluctuations.
- Can this switch be used in corrosive environments? Yes, the NEMA 4X rating and diecast aluminum enclosure are specifically designed for wash-down areas and corrosive atmospheres.
- How do I adjust the setpoint? Adjustments are made internally via a reference dial and adjustment screw located behind the removable cover to prevent unauthorized tampering.
