Frequently Asked Questions
What is the maximum load the P45 float switch can handle?
The P45 switch is rated for a maximum contact load of 10 W at 220 V AC, with a switching current of 0.5 A and carry current up to 1 A. Its low contact resistance of 100 mΩ ensures reliable operation.
Do I need an external power supply to operate the P45 float switch?
No, the P45 operates via a sealed mechanical switch inside the float. As the liquid level changes, the float actuates the internal contacts directly—no additional power or electronics are required for sensing.
How do I install the P45 float switch in my water tank?
Attach the float switch to the tank wall at your chosen level using a suitable clamp or bracket. Connect the two output leads to your pump/control circuit, ensuring proper insulation. Test the setup by filling the tank to confirm the float movement triggers the switch as expected.
