Square D A25.2 Thermal Unit

Product Description

The Square D A25.2 is a thermal unit designed for motor protection. It safeguards motors, controllers, and branch circuit conductors from excessive heat caused by overcurrents, including locked rotor currents. This protection mechanism is essential to prevent damage to motors and other circuit components due to high currents, which can lead to short circuits or grounds. Class 20 thermal units like the A25.2 react to overload current conditions within a short time. They are built with a one-piece construction for reliability. When overload occurs, a special solder melts, which allows a ratchet wheel to disengage, thus opening the control circuit contacts and motor contacts.

• Calibration is set for a range of motor full load currents.
• Provides overload protection for most motors.
• One-piece thermal unit construction ensures durability.
