The Allen-Bradley 100-D250EZY11 contactor is a 250 Amps rated 3-pole IEC contactor. It features an electronic coil. The control voltage for which the electronic coil is rated is 48 to 72 Volts DC. The 100-D250EZY11 contactor is part of the Allen-Bradley Bulletin 100-D series which includes contactors with current ratings ranging from 115 to 860 Amps. This series of contactors offers electronic or conventional coils with AC or DC coil voltages available in different ranges. The electrical lifespan of the 100-D250EZY11 contactor varies with the current: it is 1 million operations at 115 Amps and 10 million operations at 90 Amps. The maximum current carrying capability of the 100-D250EZY11 contactor is different for 3-phase or single-phase AC applications.
For single-phase AC applications, the Allen-Bradley 100-D250EZY11 contactor can carry up to 350 Amps of current at 50 Hertz and 40 degrees Celsius. When used for switching applications at 40 degrees Celsius, the contactor is rated for 315 Amps of current when it is installed as open equipment and for 270 Amps of current when enclosed. According to the IEC standards, the 100-D250EZY11 contactor has a 1000 Volts isolation voltage rating and according to the UL/CSA standards, the contactor has a 600 Volts isolation voltage rating. The current rating of the 100-D250EZY11 contactor derates by 15% if the temperature rises from 60 to 70 degrees Celsius. Only spare parts and accessories manufactured by Allen-Bradley should be used for contactor maintenance and repairs. The reliability and safety of the device will be affected if this recommendation is not implemented. The weight of the 100-D250EZY11 contactor is 7.5 kilograms.
