Description
The Honeywell L4079B1058 Pressuretrol Controller is a rugged, high-pressure limit switch engineered for demanding industrial and HVAC environments. When system pressure climbs above a set threshold (5–50 PSI), it triggers an automatic electrical circuit break—protecting equipment integrity and maintaining operational safety. This manual-reset device ensures that system faults don’t go unnoticed, demanding attention before reuse.
Specifications:
- Max Pressure (PSI): 85
- Switch Action: SPST break on pressure rise
- Max Operating Pressure: 50 psi
- Operating Range (psi): 5 psi to 50 psi
- Min Operating Pressure (PSI): 5
