ALLEN BRADLEY 100-EAH0050-PAC

Overview

ALLEN BRADLEY 100-EAH0050-PAC is a contactor coil assembly for the Allen‑Bradley Bulletin 100‑E series IEC contactor frame, compatible with the 100‑E50 size contactor. The suffix PAC defines the coil voltage and revision configuration for factory traceability and spare record management. ALLEN BRADLEY 100-EAH0050-PAC is a replacement coil spare, widely supplied as exchange spare for 100‑E contactor cabinet overhaul and on-site repair without replacing the full contactor unit.

Features

ALLEN BRADLEY 100-EAH0050-PAC is an electronic wide-range coil assembly designed for the 100‑E50 contactor. It stabilizes pull-in and holding performance and improves immunity against control circuit voltage fluctuations, reducing nuisance dropout under poor power quality conditions. ALLEN BRADLEY 100-EAH0050-PAC is a direct plug-in replacement part, which can be swapped while the main contactor frame and power terminals remain installed. It works with matched contact kits, auxiliary contact blocks and mechanical interlock accessories of the 100‑E platform. ALLEN BRADLEY 100-EAH0050-PAC has low holding power consumption compared with conventional AC coils, lowering continuous energy draw on the control circuit. It conforms to UL and CE standards for cabinet mounting.

Specs

ALLEN BRADLEY 100-EAH0050-PAC Compatibility: Allen‑Bradley 100‑E50 IEC contactor. Type: electronic coil assembly. Suffix PAC: factory voltage and revision variant. Installation: internal coil replacement for contactor. This is not a complete contactor; it is only the coil spare assembly. ALLEN BRADLEY 100-EAH0050-PAC is widely supplied as service replacement spare for contactor coil burnout and control circuit fault repair.

Principle

ALLEN BRADLEY 100-EAH0050-PAC receives control voltage from the PLC, relay or control power supply. When energized, the coil generates magnetic force to close the contactor’s main and auxiliary contacts. When de-energized, the magnetic field collapses and contact springs return the contacts to open state. The electronic regulation circuit inside ALLEN BRADLEY 100-EAH0050-PAC compensates for voltage variation, maintaining consistent magnetic pull and protecting the coil from overvoltage damage. Auxiliary contact status signals are sent to the PLC and SCADA for remote running indication and fault logging.

Applications

ALLEN BRADLEY 100-EAH0050-PAC is deployed for pump, fan, conveyor and motor starter cabinets using Allen‑Bradley 100‑E50 contactors. It is selected for spare inventory and maintenance projects to restore contactor operation by replacing only the failed coil assembly.
