Air compressor pressure switch

The Square D 9013FH pressure switch controls air compressors with a factory on/off setting of 105/135 psi. It uses a standard action mechanism and DPST electrical contact form. The switch covers a pressure range of 40 to 150 psi with a 30 psi differential. It is rated for NEMA 1 environments.

Single port 1/4 in FNPS connection

The unit mounts via one 1/4 in FNPS port and requires no unloader valve. Manual Auto/Off switch action lets the operator select automatic cycling or manual shut-off. It supports up to 10 A and handles motor loads of 1-1/2 hp at 120 V single-phase, 2 hp at 240 V single-phase, 3 hp at 240 V three-phase and 1 hp at 480 V three-phase.

Standard action with NEMA 1 rating

The switch operates without a dedicated unloader, relying on its standard action to manage cut-in and cut-out cycles. NEMA 1 rating indicates protection against falling debris in indoor locations. Power draw varies with the connected motor load up to the listed horsepower ratings. No fan or active cooling is included.
