Ashcroft B424BXCYLM3000 Pressure Switch SPDT 300-3000 psi
Pressure switch with a 300 to 3000 psi range and SPDT contacts rated 15 A at 125, 250 and 480 V AC
- Pressure range covers 300 to 3000 psi for high-pressure systems
- SPDT contact form enables both normally open and normally closed wiring
- NEMA 13, 3, 4 and 4X ratings protect against dust, water and corrosion
- AC rating 15 A at 125, 250 and 480 V suits industrial control circuits
- Diaphragm actuation with 80 to 235 psi differential provides repeatable switching
Industrial Pressure Switch for Hydraulic Systems
The Ashcroft B424BXCYLM3000 is a diaphragm-actuated pressure switch built for hydraulic and pneumatic circuits operating between 300 and 3000 psi. Its SPDT contact form provides a single changeover circuit for direct control of starters, contactors or alarm panels in machine-shop environments.
Sustained Operation Within NEMA-Rated Enclosure
The switch carries a NEMA 13, 3, 4 and 4X rating, meaning the enclosure resists oil, dust, rain and hose-directed water during continuous duty. AC contacts are rated at 15 A across 125 V, 250 V and 480 V, while DC ratings reach 6 A at 30 V and 0.5 A at 120 V, so load switching remains stable over long cycles without derating.
Verify Port Thread and Differential Before
The unit offers one 1/4 inch FNPT pressure port and a fixed differential span of 80 to 235 psi with factory on/off points set at 90 percent of range. Confirm that your system thread matches 1/4 FNPT and that the required deadband falls inside the 80–235 psi window, otherwise the switch will not trip at the desired pressures.

Questions about this item
How much heat does the SPDT contact generate when switching 15 A at 480 VAC continuously?
The contacts are rated 15 A at 480 VAC, 15 A at 250 VAC and 15 A at 125 VAC; at rated load the switch dissipates minimal heat because the diaphragm actuation has no internal heater.
What pipe fitting do I need to connect the 1/4 in FPT port to my hydraulic line?
The switch has a single 1/4 inch female NPT port, so you must supply a matching 1/4 inch male NPT adapter or hose fitting.
Will the NEMA 13 enclosure protect the switch if mounted next to an older NEMA 4 panel?
This unit carries NEMA 13, 3, 4 and 4X ratings, so it meets or exceeds the dust, water and oil-tight requirements of a NEMA 4 enclosure.
