Johnson Controls P72LB-1C Pressure Control

Johnson Controls P72LB-1C Pressure Control is a reliable dual-type control designed for condenser fans, air conditioning, head-pressure control, and commercial refrigeration. Operating from 100 to 500 PSI with a 65 PSI differential, it helps maintain stable cycling and system protection.

Key specifications and capabilities include a DPST, 4-circuit contact configuration, broad voltage compatibility, and rugged enclosure for demanding environments.

• Dual-type pressure control provides precise on/off cycling for compressor and fan circuitry across a 100–500 PSI operating range with a 65 PSI differential.
• DPST, 4-Circuit contacts support multi-stage control with robust switching for reliable HVAC and refrigeration performance.
• Electrical ratings cover a wide range: up to 24 A at 120 VAC (2 HP), up to 18.7 A at 208 VAC (3 HP), up to 17 A at 240 VAC (3 HP), and up to 15.9–15 A for 208–220 VAC 3-phase (5 HP), plus 125 VA at 120–600 VAC and 57.5 VA at 120–300 VDC.
• Connection uses 1/4 inch flare nut fittings for secure, leak-free piping.
• Enclosure features a durable NEMA 1/3R housing for indoor installations.
• Capillary length of 36 inches enables flexible mounting and accurate sensing.
• Applications are ideal for condenser fan cycling control, head-pressure control, air conditioning, and commercial refrigeration.
