Square D B50.0 Magnetic Starter Thermal Unit #1

Product Description

The Square D B50.0 is a magnetic starter thermal unit designed to protect motors, controllers, and branch circuit conductors from overheating caused by prolonged motor over-currents, including locked rotor currents. This unit offers a reliable response to overload conditions by tripping within twenty seconds. The construction includes a single piece design where motor current flows through a heater winding. Under overload conditions, heat generated causes solder to melt, enabling a ratchet mechanism to trip and open the control and motor contacts.

• Protects against prolonged motor over-currents
• Trips in 20 seconds or less on overload conditions
• Single-piece construction design

Product Highlights

This thermal unit is essential for the safe operation of motors and other electrical equipment, preventing damage from excess current.
