The 140U-I6C3-C35 UL Molded Case Circuit Breaker is a 3-pole, UL-listed circuit breaker belonging to the Allen-Bradley 140U molded case circuit breaker series. This circuit breaker is designed to provide short-circuit and thermal overcurrent protection to a wide range of industrial control panel applications. It comes with a smaller footprint design that makes it suitable for applications with limited panel space, and it offers up to a 6 times higher interrupting rating than other conventional circuit breakers in its class. The 140U-I6C3-C35 Circuit Breaker is ideal for control circuit applications (control transformers and power supplies), feeder circuits (distribution panel, branch circuit, and transformer circuits), HACR (Heating, Air Conditioning, and Refrigeration), and high-intensity discharge applications.

The 140U-I6C3-C35 Circuit Breaker has a nominal current rating of 35 Amps, and it is designed for a circuit with an operating voltage range between 230 Volts AC and 690 Volts AC. This circuit breaker has an interrupting rating of 65 kA, and a rated impulse withstand of 6000 Volts. It has an insulation voltage rating of 750 Volts and a mechanical life span rating of 100,000 operations. The 140U-I6C3-C35 Circuit Breaker has a fixed magnetic and a fixed thermal trip unit that provides fixed thermal and short-circuit protection by using a reverse loop contact and a bimetal heat element that deflects the incoming load heat to the element, causing a trip action. The 140U-I6C3-C35 Circuit Breaker comes with a standard end cap terminal and it is supplied with mounting hardware for easy field installation. The 140U-I6C3-C35 Circuit Breaker supports installation at a maximum altitude of 2000 meters without de-rating, and it has a rated permissible temperature range of -8 to 60 degrees Celsius.
