The 100-D110ZD22L contactor is a 110 Amps-rated industrial contactor. It is a 3-pole contactor with 3 main contacts that belongs to the 100-D family of IEC 100 contactors from Allen-Bradley. The 100-D contactors are available with either electronic or conventional coils. The 100-D110ZD22L contactor features a conventional coil with a 110 Volts DC coil voltage rating. A total of 4 auxiliary contacts are available on the 100-D110ZD22L contactor which include 2 NO contacts and 2 NC contacts. One NC auxiliary contact is a late break contact. Only trained and qualified technical personnel should handle and install the contactor. During contactor maintenance, the contactor should be powered off. Only original Allen-Bradley spare parts should be used to ensure contactor reliability. Allen-Bradley recommends that the arc chute and the main contacts be checked after a short circuit.

The Allen-Bradley 100-D series 100-D110ZD22L contactor is mechanically locked when the arc chute is removed. The arc chute is mechanically locked when then the contactor coil is energized. The contactor must be switched off before the arc chute can be removed. If the short circuit leads to welded contacts, then the arc chute can be removed by exerting more force on it than usual. It may be possible to remove slight welds by using a screwdriver. Care must be taken to not bend the contacts when trying to remove the slight welds. In case of damage, the main contacts on the 100-D110ZD22L contactor, the coil, and the auxiliary switch block can be replaced. The maximum operating temperature for full power operation is 60 degrees Celsius. Contactor operation at 70 degrees Celsius is possible too but it leads to 15% derating in the contactor's current carrying capacity.
