The Allen-Bradley 140U-D6D3-B30 is a high-performance molded case circuit breaker designed for industrial control and panel applications, offering robust overcurrent protection with its 480-volt supply voltage and 60 Hertz frequency rating. With a compact design that saves up to 50% of space compared to other breakers, it features a 3-pole configuration, a D Frame type, and boasts a remarkable interrupting capacity of 100 kA with a rated current of 3 Amps. Additionally, it provides both magnetic and thermal trip currents which can be fixed or adjustable, making it ideal for use as feeder breakers or single circuit breakers in scenarios requiring reliable disconnection, short-circuit, and thermal protection, with auxiliary contacts that signal the breakers operating status clearly as ON or OFF.
