Allen Bradley 140MT-D9E-B63


The Allen Bradley 140MT-D9E-B63 is a motor protection circuit breaker (MPCB) designed for frame size D, covering a current range of 4 to 6.3 amps. This standard magnetic trip device offers reliable protection against short circuits and thermal overloads for motors up to 40 amps. Its robust performance ratings allow for motor starters to be assembled without the need for extra branch circuit protection, simplifying your setup. Additionally, the breaker supports tap conductor ratings that enable the use of smaller wiring in grouped motor applications, which can help reduce installation costs. When used in three-component starter configurations, this motor circuit protector is typically paired with a separate overload relay. Products like this Allen Bradley MPCB are available through BSP Automation, ensuring easy access to high-quality industrial control components.
