MWT145 Generic Over Temperature Cut-Out 145 Degrees 10A, Universal Thermal Safety Cut-Out for Appliances

MWT145 is a generic over temperature cut-out that trips at 145 degrees and is rated to carry 10A. Thermal cut-outs like this sit in the heating circuit of many appliances and kill the power if things run too hot. It isn't made for one brand, so compare the temperature, current rating, mounting style and terminals with the part you're taking out before ordering.

How an over temperature cut-out protects an appliance

The cut-out is a safety device clamped against a hot surface or mounted in the airflow. Below 145 degrees its contacts stay closed and current flows normally. If a thermostat sticks, a fan stops or vents block, the temperature climbs past that point and the contacts open, switching off the heat. Some cut-outs reset when they cool, while others are one-time devices that must be replaced. A tripped or failed cut-out usually shows up as an appliance that won't heat at all, or one that heats and then drops out. Always find out why it tripped.

Replacing a thermal cut-out

Isolate the appliance at the power point or switchboard first. Note how the old cut-out is mounted, because it needs firm contact with the same surface to sense heat properly. Use matching terminals or crimp connectors and keep the wiring away from hot metal. Hard-wired appliances must be repaired by a licensed electrician, and the cause of the overheating should be fixed before the appliance goes back into service.

Questions about this part

Can I fit a cut-out with a different temperature?

No. Use the same trip temperature as the part you're replacing. A higher rating lets the appliance overheat before it cuts out, and a lower one causes nuisance tripping. This one is 145 degrees at 10A, so match both figures to your old part.
