Description
The Johnson Controls P170KA-1 is a dual-circuit refrigeration pressure control engineered for dependable high-pressure protection in non-corrosive refrigerant systems. With a 4-wire, 2-circuit design, this control simultaneously manages two independent load lines — Line M1 closes on high pressure while Line M2 opens on high pressure — providing versatile system protection and control logic in a single device.
Key Features
- 4-wire, 2-circuit configuration for independent dual-line control
- Line M1: Close on High pressure action
- Line M2: Open on High pressure action
- Wide operating range: 50 PSI to 500 PSI
- Manual reset lockout for added safety and fault awareness
- 1/4″ Male Flare connector for straightforward field installation
- Designed for use with non-corrosive refrigerants
- All-range control suitable across a broad spectrum of refrigeration applications
Application
The P170KA-1 is ideal for commercial and industrial refrigeration systems where dual-circuit high-pressure monitoring is required. The manual reset lockout feature ensures that a system cannot automatically restart after a high-pressure trip event, requiring technician intervention before resuming operation — a critical safety measure that helps protect compressors and system components from repeat high-pressure faults.
