The Schneider Electric XB2BD33C is a complete 22mm panel-mounted, 3-position selector/rotary switch from the Easy Harmony XB2 / ZB2 metal series. Built with a chromium-plated metal bezel and a heavy-duty Zamak fixing collar, this assembly includes a black standard handle operator head and a dual contact arrangement (2 NO). It is designed to provide reliable manual control for selecting operating modes (e.g., HAND - OFF - AUTO) in industrial automation systems.

Features

• Maintained 3-Position Rotary Action: Remains locked in any of the three selected positions (Left, Center, or Right) until turned manually, preventing accidental mode shifts.
• Rugged Chromium-Plated Metal Body: Built with a solid metal bezel and Zamak fixing collar, offering high mechanical durability, shock resistance, and grounding continuity for harsh industrial panel environments.
• 2 NO Dual Contact Circuit Layout: Includes two independent Normally Open contact blocks. Rotating the handle toggles the contacts depending on the handle position:
  • Left Position (Position 1): Contact Block 1 Closed (13 - 14), Contact Block 2 Open.
  • Center Position (Position 0): Both Contact Blocks Open (System OFF / Neutral state).
  • Right Position (Position 2): Contact Block 1 Open, Contact Block 2 Closed (23 - 24).
• Modular Snap-On Base Assembly: The operator head connects to the rear contact block base via a clip-assembly mechanism, enabling quick contact block additions or field replacements.

Common Applications

• HAND - OFF - AUTO (HOA) Control Networks: Selecting between manual override (HAND), full shutdown (OFF), and automated PLC sensor loops (AUTO) on industrial pump and HVAC panels.
• FOR - OFF - REV Motor Control: Triggering forward, stop, and reverse contactor coils for motor reversing applications.
• LOCAL - OFF - REMOTE Switching: Toggling system control between a local push-button station and a remote supervisory PLC/SCADA terminal.

Installation & Wiring Guide

• Panel Cutout Prep: Drill or punch a standard $22.5\text{mm}$ hole into the enclosure door.
• Mount Operator Head: Insert the 3-position black selector head through the front face of the cutout.
• Attach Metal Collar Assembly: Slide the Zamak fixing collar onto the back of the head from inside the panel. Tighten the metal locking screw ($0.8\text{--}1.0\,\text{N}\cdot\text{m}$) to secure and ground the assembly to the panel face.
• Wire Contact Blocks:
  First NO Block (Terminals 13 - 14): Wire into your "HAND" or "MANUAL" run circuit.
  Second NO Block (Terminals 23 - 24): Wire into your "AUTO" or "REMOTE" run circuit.
  (Center position leaves both 13-14 and 23-24 open for an "OFF" state).
