140U-K6D3-D35

The Allen-Bradley 140U-K6D3-D35 Circuit Breaker is a K-Frame Molded Case Circuit Breaker (MCCB) with a supply voltage of 480 Volts, a rated current of 350 Amps, an interrupting current of 65 kA, and a 3-pole configuration. The circuit breaker provides Fixed Thermal/Adjustable Magnetic (T/M) protection. It provides circuits with protection against overload, short-circuit, and ground fault situations. It is found in both branch and main circuit protection devices, for example, individual enclosures, panelboards, bus-bar trunking tap-offs, and switchboards. The Allen-Bradley 140U-K6D3-D35 Circuit Breaker complies with various international standards such as the IEC 157-1, UL489, CSA 22.2 No.5, KEMA-KEUR, CCC, and CE standards. The Allen-Bradley 140U-K6D3-D35 Circuit Breaker has also been accredited with certifications that include the CCC, CE Mark, CSA, and UL standards and it is appropriate for use with the IE3 Motors (IEC 60034-30).

The Allen-Bradley 140U-K6D3-D35 Circuit Breaker is a K-Frame Molded Case Circuit Breaker (MCCB) with a mechanical life of 20,000 operations or 120 operations per hour and an electrical lifespan of  60 operations per hour at 415 Volts AC. The circuit breaker is designed to accommodate a current rating of 350 Amps and a breaking capacity of 65 kA. It has a wide range of accessories such as Terminal Shields, a Flex-Cable Operating Mechanism, a Rotary Variable-Depth Operating Mechanism, a Rotary Direct Couple Operating Mechanism, an Operating Handle Extension, Phase Barriers, a Padlock Kit, Terminal Lugs, and an End Cap Kit. The 140U-K6D3-D35 Circuit Breaker has an ambient temperature of 104 degrees Fahrenheit (40 degrees Celsius) without derating and a storage temperature range from -40 to 176 degrees Fahrenheit (-40 to 80 degrees Celsius). It has dimensions of 140 x 108.5 x 205 millimeters.
