140U-M6D3-D70

The Allen-Bradley 140U-M6D3-D70 Molded Case Circuit Breaker (MCCB) comes with a Size M frame, 3 poles, and 800 Amps of frame current. It has 690 or 600 Volts AC of rated operational voltage, 800 Amps of rated current, 50/60 Hertz of rated frequency, and 55 Kiloamps of interrupting rating. The protection mechanism for the breaker is fixed thermal or adjustable magnetic. Its approximate weight is 43.9 pounds. This circuit breaker has a powerful arc-suppression unit that is specifically designed to absorb and suppress the generated arc quickly. It has a high current-carrying capacity and a breaking capacity with high reliability. This MCCB provides isolation and short circuit protection for industrial control panels. It provides the facilities to disconnect the main control panel.

The 140U-M6D3-D70 Molded Case Circuit Breaker consists of a mechanical switch that is capable of breaking a circuit in a short circuit situation. An insulation terminal kit, phase barriers, a shunt release, and an under-voltage release are some of the accessories that are available with this breaker. Its isolation function ensures the safety of the equipment by separating the equipment from all the electrical energy sources. The 140U-M6D3-D70 MCCB can be used for the protection of the feeder circuit of industrial control panels. However, it is not suitable for applications that require frequent switching. The breaker has a high breaking capacity and high switching durability. The 140U-M6D3-D70 MCCB provides overload protection via temperature sensitive components. It helps to protect both the users and the equipment from overcurrent conditions. This breaker can be used as a switching and protection device for industrial motors, capacitors, and transformers. It provides automatic resetting after fault clearance. This MCCB does not require intensive maintenance, but periodic inspection will keep the breaker performing well.
