Description

Overview

The LP3 Low Pressure Indicator Switch provides a clear warning when system pressure drops below a safe level. It suits heavy trailer and prime mover air systems and, as a result, helps operators catch faults early. Additionally, its double-terminal design simplifies wiring for light and buzzer circuits.

Features

• LP3 style low pressure indicator with double terminals
• Factory set cut-out 60 psi ±6 for consistent warnings
• 1/4 NPT male thread for straightforward installation
• Designed to trigger lamps or buzzers for driver alerts

Specifications and Materials

Part number: AB8342.
Model: LP3. Pipe thread: 1/4 NPT. Cut-out pressure: 60 psi ±6. Terminals: two, isolated. Typical use: pressure-operated electropneumatic switch for warning circuits.

Compatibility and Fitment

Mount the switch into a reservoir or manifold at a high point for drainage, then wire the two terminals in series with the ignition and warning device. Finally, confirm activation occurs near the specified cut-out while reducing system pressure.
This cross-reference listing means this valve is a suitable replacement for the part numbers and applications shown. Some changes in air line plumbing may be required. 228750, JNY0821A, T239100D, LP-3.

Compliance and Safety

Work on a depressurised system only. Next, torque the threaded connection to the vehicle specification and seal with an appropriate thread compound. After installation, leak test and verify the warning lamp and buzzer operate when pressure falls through the cut-out band.

Trailer Applications

Use the SCTEG LP3 Low Pressure Indicator Switch on heavy trailers and road trains that require an audible or visual low-air warning. Moreover, it suits retrofits where an LP-3 style device replaces an older indicator, provided the pressure setting and 1/4 NPT thread match the existing system.
