LS Auxiliary Contact 1 NO 1 NC Model UA-2
The auxiliary contact of the thermal switch is designed to provide greater control over the circuit and can be opened or closed as needed. These auxiliary contacts are used for all thermal switches within the range of 0.63 to 100 amperes, and their blades can change status — blades that were open can close, and those that were closed can open. This contactor is installed from the top and is essentially mounted onto the thermal switch.

Features of the thermal switch auxiliary contact Thermal switches operate similarly to bimetals and work based on the coefficient of linear expansion of metals. When an overload current passes through, the metals heat up and bend towards the metal with the lower coefficient of linear expansion, causing the contact to open or close and thus breaking the circuit. These switches can interrupt the circuit under load and a key advantage is that thermal switches are among the best and most reliable protectors for electric motors, able to break the circuit without directly commanding the contactor.
