Eaton Cutler-Hammer XTCEXFAC11 Aux Contact

The Eaton Cutler-Hammer XTCEXFAC11 is a front-mounted auxiliary contact block engineered for seamless integration with XT Series contactors (Frame B-C). Featuring a 1NO/1NC (1 Normally Open / 1 Normally Closed) contact configuration, this component provides essential feedback signals to control circuits, enabling precise motor status monitoring and interlocking. Designed for high-cycle industrial environments, the XTCEXFAC11 utilizes screw-terminal connections to ensure secure, vibration-resistant terminations. As a core component of the Eaton XT IEC control lineup, it facilitates complex motor control center logic without increasing the footprint of the primary contactor. Contractors rely on this front-mount auxiliary switch for its reliable switching performance in HVACR control panels and automated machinery. Its dual-pole design allows for simultaneous signaling of RUN and STOP status, making it a critical asset for maintaining system safety and operational transparency in 3-phase power applications.

• Snap-On Front Mounting: Minimizes labor time by attaching directly to the contactor face without tools.
• Bifurcated Contact Design: Ensures high contact reliability even in low-voltage signaling applications.
• NEMA/IEC Compliance: Meets global standards for industrial control equipment, ensuring compatibility in multi-brand panels.
• Space Efficiency: Occupies zero additional DIN rail space by utilizing the contactor’s front-facing interface.

Is the XTCEXFAC11 compatible with all Eaton contactors?
No, this specific model is designed for XT Frame B through C contactors (up to 32A). For larger frame sizes, side-mount or specific frame-match auxiliaries are required.

Can I use this for both AC and DC control circuits?
Yes, the XTCEXFAC11 contacts are rated for various pilot duty applications, but always verify the specific amperage draw of your coil or PLC input against the IEC 60947-5-1 ratings.

Does this block support overlapping contacts?
This is a standard 1NO/1NC configuration. If your logic requires "Make-Before-Break" functionality, you must specify an EM (Early-Make) or LB (Late-Break) variant.
