Trying to figure out exactly what this is. I have a battery powered backpack sprayer. Obviously was not working. Traced the power until I found the break in the line and it is this critter. This is inline between the switch and the pump. The pump just pumps air into the tank pressurizing it. The pump works fine bypassing this component. The numbers on the component indicate 5amps/250volts. I am guessing is a current limiter or possibly an inline circuit breaker. Guessing that as the pressure increases it causes the pump to draw more current until 5amps cuts it off thus stopping the sprayer from over pressurizing. The problem is as much as I’ve searched I can’t find one like it online so I’m not quite confident in my reasoning. Dosas anybody actually know what this is and where I can get one?
