Square D A3.61 Thermal Unit

Product Description

Square D A3.61 is a thermal unit designed to protect motors, controllers, and branch circuit conductors from overheating. It handles prolonged motor overcurrents, including locked rotor currents. In case of excess current, other components like fuses or circuit breakers provide additional protection. This Class 20 thermal unit is built to trip within 20 seconds under overload conditions. It features a one-piece construction that allows motor current to flow through a heater winding. Under overload conditions, the heat causes a solder to melt, freeing a ratchet wheel that opens control circuit contacts and motor contacts.

• Designed to protect motors and controllers
• Tripping mechanism activates within 20 seconds on overload
• One-piece construction for reliability
