United Electric J40-230 Pressure Switch
The United Electric J40-230 Pressure Switch is a high-performance 0-100 PSI mechanical pressure switch designed for critical monitoring in industrial HVACR and process control systems. Engineered with a durable phosphor bronze bellows and brass 1/4" NPT female pressure connection, this unit ensures reliable set point repeatability within a compact skeleton construction enclosure. As the direct updated version of the legacy J40-2309624, the J40-230 provides seamless field replacement for aging hardware while maintaining a 15A SPDT switch output for precise alarm and shutdown functions. The adjustable setpoint allows technicians to dial in thresholds between 0 and 100 PSI, while the sealed bellows sensor offers a leak-free solution for applications where elastomers are unsuitable. Built for OEM solutions and harsh environments, this UE J40 series switch features an internal adjustment screw and direct-to-switch terminals to facilitate rapid installation and long-term stability in power generation, medical sterilization, and pneumatic systems.
Key Benefits
- Broad Compatibility: Direct replacement for United Electric J40-2309624 with standard 1/4" NPT ports.
- Robust Sensing: Features phosphor bronze bellows to handle process media without the risk of elastomer degradation.
- Industrial Rating: The 15 Amp SPDT contact manages heavy resistive loads up to 250V AC effortlessly.
- Compact Footprint: Open-frame (skeleton) design fits easily into tight control panels and equipment enclosures.
- External Adjustability: Simplified set point tuning via a hex-head screw, providing 1% full-scale accuracy.
Common Questions
How do I adjust the pressure set point on the J40-230?
Using a calibrated pressure source and a small screwdriver or probe, turn the internal adjustment screw clockwise to increase the pressure threshold or counter-clockwise to decrease it. Always verify the setting against a manual gauge during commissioning.
Can this switch be used for vacuum applications?
While the J40 series includes vacuum models, the J40-230 is specifically calibrated for a pressure range of 0-100 PSI. For vacuum-specific requirements, a separate model from the J40 catalog may be required.
What is the proof pressure limit for this model?
The proof pressure for the J40-230 is rated at 110 PSI. It is critical never to exceed this limit, even during system surges or testing, to prevent permanent damage to the bellows sensor.
