Square D A11.0 Thermal Unit, Type S, Type A, melting alloy, Class 20

Product Description

The Square D A11.0 Thermal Unit is designed to provide motor protection by disconnecting electrical current in the event of overheating caused by prolonged over-currents. This unit is ideal for use with motors, controllers, and branch-circuit conductors, safeguarding them against high temperatures and electrical faults.

• Protects motors from overheating due to extended over-currents.
• Trips in 20 seconds or less during overload conditions.
• Designed with one-piece construction for reliability.

Product Highlights

This thermal unit functions by utilizing a heater winding that generates heat when overload occurs. The heat causes a special solder to melt, activating a ratchet mechanism that opens the control circuit and disconnects the motor.
