About 140U-MTD3-D45

The 140U-MTD3-D45 trip unit is an interchangeable thermal-magnetic trip unit for M-frame circuit breakers which belongs to the Bulletin 140U series from Allen-Bradley. The rated current for the 140U-MTD3-D45 trip unit is 450 Amps at 40 degrees Celsius, the thermal trip setting is also 450 Amps and the magnetic trip can be configured between 2250 Amps and 4500 Amps. Trip units for M-frame devices like this one have metal tabs that prevent them from being seated in Q-frame side plates. Furthermore, the M-frame trip units also have angles on the load end which only fit into the shapes that are machined into the load conductors on M-frame devices. The 140U-MTD3-D45 trip unit should be inspected prior to installation. The installation of any internal accessories should be carried out before the trip unit is installed into another device such as a circuit breaker.



 



The nameplate information on the 140U-MTD3-D45 trip unit should be matched with custom system requirements. The circuit breaker into which the 140U-MTD3-D45 trip unit is being installed should be tripped prior to the installation of the trip unit. This will help to protect the trip unit from potential damage. The magnetic setting on each pole of the trip unit can be adjusted by suitably rotating the adjustment buttons with the help of a screwdriver. Care must be taken to ensure that these adjustment buttons are set at detents and not at any of the intermediate positions. The cover on the 140U-MTD3-D45 trip unit is factory sealed to prevent calibration tampering. The 140U series devices such as the 140U-MTD3-D45 trip unit comply with standards set by multiple globally recognized bodies including the UL 489, CE, CSA, and KEMA – KEUR standards.
