The 140U-I6C3-C20-M Molded Case Circuit Breaker is an industrial-based circuit breaker by Allen-Bradley that is designed to provide thermal overcurrent protection and short-circuit protection to a wide variety of industrial control panel applications. The 140U-I6C3-C20-M Circuit Breaker belongs to the discontinued I-Frame circuit breaker series, it is designed with a small footprint for tight panel space applications, and it also comes with up to 6 times higher interrupting ratings than traditional breakers. The 140U-I6C3-C20-M Circuit Breaker is designed for control circuits, HACR (Heating, Air Conditioning, and Refrigeration) applications. The 140U-I6C3-C20-M Molded Case Circuit Breaker comes with non-interchangeable trip units and lugs and it can be wired for IP2X ratings.
The 140U-I6C3-C20-M Circuit Breaker has a nominal current rating of 20 Amps and a high breaking capacity of 65 kA. It has an acceptable voltage range between 230 Volts AC and 690 Volts AC (50/60 Hertz) and a rated impulse withstand of 6000 Volts. The 140U-I6C3-C20-M Circuit Breaker has a 100,000 operations mechanical life cycle, and a 10,000 operations electrical life cycle. It comes with a non-interchangeable thermal and magnetic trip unit that offers fast-acting thermal and instantaneous trip actions via a bi-metallic heat element and a reverse loop contact. It comes with the standard end cap line and load side terminals, and it is shipped with mounting hardware that allows for easy field installation. The 140U-I6C3-C20-M Circuit Breaker has an operating temperature range of -8 to 60 degrees Celsius and a maximum installation height of 200 meters without de-rating.
