ULTIMHEAT : Snap action contact airswitch. Type ZP

Momentary or alternate action : Type ZP

DIMENSIONS

Uses: High electrical rating, for 250V.

Main applications: Direct actuating of pumps and blowers in spas and swimming pools, sink erasers, professional or home appliances used with risks of water splashing. Resist to spas and swimming pools ozone concentration.

Membranes: EPDM, dia 22 mm. Silicone or NBR on request. Double membrane on request.

Fluid: air

Fitting: Plastic spout for 1/8(3mm) or 1/16(1.5mm) ID flexible plastic tubing maximum hardness 70 shore A

Pressure: positive

Housing:PA66, UL94 VO and ABS

Contact: SPNO or SPDT, snap action. SPNC contacts available with MOQ

Electrical rating: Depends on micro-switch operating force that is linked to the electrical rating - Standard rating micro-switch (medium and high pressure calibration only): 16A 125/250VAC;1/2HP 125VAC; 3/4HP 250VAC - High rating micro-switch (medium and high pressure calibration only): 2HP 240V, 21(8) A 240V (UL, CSA VDE switch) - Low force micro-switch (set points less than 150 mbar): 1/4HP 6(1) A 240V ( UL, CSA VDE switch)

- On request: up to 25A 250V Action: momentary or alternate (Latching). Electrical connection: 6.35 x 0.8 mm quick connect terminals

Maximum pressure: 4 bars (58 PSI)

Ambient temperature limits: 0 to 85°C

Barometric compensation: groove on 4 mm spout for ¼ NPSM, calibrated orifice on 9/16-18

Caution: This compensation is skipped if using ¼ thread for pressure connection

Mounting fittings: ¼” NPSM or 9/16-18 (2 possible flat positions)

Switch operation: Operates on a sealed pressure air displacement. Do not use pressure transmitters with air input to avoid pumping action.

Use air transmitters with enough air volume to achieve minimum operating pressure.

Caution: too long connecting tubing and/or too small pressure transmitter will not operate the air switch or will operate it with a momentary action.

Accessories: shipped with plastic nut. Maximum tightening torque with plastic nut is 0.08mkg (0.8Nm).

Recommended value: 0.5 Nm . Stainless steel nut or tube securing nut (*) on request
