100-D140ZJ11L

The Allen-Bradley Bulletin 100-D 100-D140ZJ11L contactor is a contactor with 2 auxiliary contacts. One of the auxiliary contacts is normally closed and it is a late break contact. The other auxiliary contact is a normally open auxiliary contact. The 100-D140ZJ11L contactor is a 3-pole IEC contactor that is rated for 140 Amps. It is controlled by a conventional coil that is rated for 24 Volts DC. The 100-D140ZJ11L contactor can be used for both single-phase and 3-phase applications. The Bulletin 100-D contactors can be operated with AC or DC coils that are conventional or electronic and that are rated for a wide range of voltages. The Bulletin 100-D contactors also come with IP 00 protection ratings, making them suitable for indoor use only. They also only support panel mounting. The optimal temperature range for contactor operation is from -20 to +60 degrees Celsius.

Operating the Bulletin 100-D 100-D140ZJ11L contactor outside the ambient temperature range recommended by Allen-Bradley has 2 major drawbacks: the first is that the contactor performance degrades because the operating current is reduced and the second is that the contactor can become damaged by extreme temperatures. The contactor should also be protected from corrosive vapors and dust during operation. If a short circuit occurs, the 100-D140ZJ11L contactor must be inspected before being put into operation. One possible result of a short-circuit is that the contacts can get welded. This welding has to be removed before the contactor can be operated again. Some welds can be removed with a screwdriver. Allen-Bradley recommends that only original spare parts be used for repairing faulty contactors. The use of substandard or unauthorized accessories or spare parts can lead to problems with the 100-D140ZJ11L contactor’s operation.
