Switches are rated for resistive loads. See our Electrical Considerations for UL guidelines for current (Amperes resistive) at different voltages, PBT is not suitable for use in water above 149°F (65°C). Wires are rated for 60°C where exposed to oil
Side-mounted liquid level switch has a PBT stem and a PBT float. PBT is a stong plastic that features excellent structural integrity. It is best used where temperature resistance and permeability are not factors such as fuel and hydraulic systems up to 120 degrees C. The M7700 is not for use in hot water applications above 65 degrees C. For acidic conditions, such as found in electroplating and metal cleaning. Maximum temperature: 130 degree C. Fittings: 1/2" NPT x 1/2" NPT. Nominal current rating(s): 30 VA SPST Switch. Float SG: 0.7. Maximum pressure: 100 psig. Lead wires: 22 gallon Teflon 24".
