140U-K6L3-D40

The Allen-Bradley 140U-K6L3-D40 Molded Case Circuit Breaker (MCCB) has a supply voltage of 480 Volts, an interrupting rating of 65 kA, a rated current of 400 Amps, and 3 poles. It provides Electronic LS protection (Long Time and Short Time). The circuit breaker is used in circuit protection devices such as individual enclosures, switchboards, panelboards, and bus-bar trunking tap-offs, It offers circuits with protection against short-circuits, ground faults, and overloading. It provides an alternative for current-limiting that supplies a life-cycle interrupt to limit the energy that is let through. The Allen-Bradley 140U-K6L3-D40 MCCB has internal control modules which include the Auxiliary Contact (AX), Alarm Contact (AL), Auxiliary/Alarm Contact (AX/AL) combination, Undervoltage Release (UVT), and Shunt Trip (SNT) modules. Also, the circuit breaker has external accessories that can be field-installed, including Terminal Shields, a Flex-Cable Operating Mechanism, a Rotary Variable-Depth Operating Mechanism, a Rotary Direct Couple Operating Mechanism, an End Cap Kit, Phase Barriers, and Mounting Hardware.

The Allen-Bradley 140U-K6L3-D40 Molded Case Circuit Breaker has been designed to conform to international standards, including the KEMA-KEUR, CSA 22.2 (No. 5), UL 489, and the IEC 157-1 standards. It also has international certifications that include the CCC, UL List, CE Mark, and CSA standards and it is appropriate for use with the IE3 Motors (IEC 60034-30). It has a compact housing design with dimensions (Width x Depth x Height) of 140 x 108.5 x 205 millimeters which save panel space. The 140U-K6L3-D40 Molded Case Circuit Breaker has a storage temperature ranging from -40 to 176 degrees Fahrenheit (-40 to 80 degrees Celsius) and a maximum ambient temperature rating of 104 degrees Fahrenheit (40 degrees Celsius) without derating.
