Product Description
The Allen-Bradley 100-D180G11 is a large-frame, 180-Amp IEC contactor from the Bulletin 100-D series, part of the IEC 100 Contactors family offering a range of sizes and current ratings (115-860 Amps) for diverse industrial applications. These 3-pole contactors are made with environmentally friendly materials, panel-mountable (not DIN rail), and have an IP00 protection rating (IP20 for auxiliary contacts). The 100-D180G11 features one normally-open (NO) and one normally-closed (NC) auxiliary contact, a 440V AC (50 Hz) conventional coil (electronic coils with AC/DC control voltages are also supported), and is designed for indoor, single- and three-phase AC applications. It has a general purpose current rating of 220 Amps, a single-phase current rating of 176 Amps at 230V AC (40 HP), and three-phase power ratings of 50, 60, 150, and 150 HP at 200, 230, 460, and 575V AC, respectively. Installation should only be performed by qualified and trained personnel.
Is Your Device Showing These Signs?
The Allen Bradley 100-D180G11 commonly experiences issues related to coil failure, resulting in contactor malfunction and motor control disruption. Technicians frequently address problems with the auxiliary contacts, which degrade over time due to arc flash and mechanical wear, leading to signal errors in control circuits. Overload relay tripping is another frequent problem, often caused by improper current settings or motor overheating, requiring adjustment or replacement of the overload block. Binding or sticking of the armature assembly is also a known issue, preventing proper contact closure and necessitating cleaning, lubrication, or component replacement to restore functionality.
