Allen Bradley 100-E265ED11 MCS-E Contactor

The Allen Bradley 100-E265ED11 is a high‑capacity contactor from the MCS‑E series, rated at 265 A for motor and power circuit switching. It is designed for heavy‑duty industrial applications such as motor control centers, power distribution panels, and HVAC systems. The contactor features a dual‑coil technology that accepts both AC and DC voltages in the range of 100‑250 V, offering flexible control options.

The unit includes one normally open (NO) and one normally closed (NC) auxiliary contact for feedback and interlocking circuits. Its compact design and high thermal capacity ensure reliable operation even under frequent cycling. The 100‑E265ED11 is built with silver‑alloy contacts for long electrical life and includes a mechanical interlock provision for reversing applications.

Key Features

• Universal AC/DC coil: Reduces inventory and simplifies design, as the same contactor can be used in both AC and DC control circuits.

• Integrated auxiliary contacts: Provides immediate status feedback to the PLC without additional block purchases.

• High short‑circuit withstand: Withstands up to 50 kA (with appropriate fuse protection).

• Visual position indicator: A mechanical flag shows the contact status at a glance.

• Modular accessories: Supports additional auxiliary blocks, surge suppressors, and timer modules.

Typical Applications

• Motor control: Starting/stopping large fans, pumps, compressors, and conveyors.

• Power switching: Control of lighting banks, heaters, and capacitor banks.

• PLC output interface: Switching high‑power loads through PLC‑controlled coils.

• Reversing contactor assemblies: Using the mechanical interlock option.

Installation and Wiring

Mount the contactor on a DIN rail or panel using the fixing screws. Connect the power conductors to the main terminals (L1, L2, L3 for input; T1, T2, T3 for output). Tighten to the specified torque (15 Nm). Connect the coil voltage to the A1 and A2 terminals. The auxiliary contacts (13‑14 and 21‑22) are wired to PLC inputs or interlocking circuits. Ensure the supply voltage matches the coil rating. For DC operation, observe polarity (A1 positive, A2 negative). Add a surge suppressor across the coil to protect PLC outputs from inductive kickback.

Compliance

The 100‑E265ED11 complies with IEC 60947‑4‑1 and UL 508, carries CE, UL, and CSA marks, and is RoHS compliant. It is rated for pollution degree 3.

Conclusion

The Allen Bradley 100‑E265ED11 contactor offers robust, high‑current switching with the convenience of a universal AC/DC coil. Its auxiliaries and durability make it a preferred component for demanding industrial control systems.
