The Schneider Electric XB5AW33B5C is a complete 22mm panel-mounted, green illuminated push-button assembly from the Harmony XB5 plastic series. Combining a double-insulated plastic operator head with an integrated 24V protected LED light block and a dual contact arrangement (1 NO + 1 NC), it serves as a human-machine interface element for machine starting, status indication, and process execution loops.

Features

• Double-Insulated Plastic Body: Built using high-impact dark grey plastic bezels and fixing collars, offering corrosion resistance against chemical agents, water washdowns, and electrical shock risks without requiring a grounding wire on the bezel.
• Dual Contact Switching (1 NO + 1 NC): Includes both a Normally Open (13 - 14) and Normally Closed (21 - 22) slow-break contact block out of the box. This enables simultaneous control actions—such as engaging a run circuit via NO while opening a standby/hold loop via NC.
• Integrated 24V LED Light Source: Powered by a long-life LED module (100,000 hours service life) operating on 24V AC/DC control voltage, producing a bright green visual indicator visible from a distance.
• Extreme Environmental Sealing (IP69K): Rated up to IP66 / IP67 / IP69K and NEMA 4X, making it suitable for food and beverage processing, marine, chemical, or outdoor control boxes subjected to hot high-pressure hose-downs.

Common Applications

• Machine Start / Run Commands: Used as the primary green "START" button where a visual green indicator confirms system readiness or active power status.
• Process Interlocking & Signal Feedback: Simultaneously energizing an operational control coil (13 - 14 NO) while disengaging an auxiliary status line (21 - 22 NC).
• Industrial Control Cabinets: Installed across standard $22\text{mm}$ control enclosures, motor control centers (MCCs), and outdoor pump stations. 

Installation & Wiring Guide

• Panel Cutout Prep: Punch a standard $22.5\text{mm}$ mounting hole into the enclosure door.
• Mount Operator Head: Push the green illuminated operator head through the front face of the cutout.
• Attach Fixing Collar: Slide the plastic fixing collar onto the back of the head from inside the panel and tighten the locking screw (0.8 - 1.2N.m).
• Wire Contact Blocks:
  
  • Terminals 13 - 14 (NO): Wire into your primary motor coil or run enable circuit.
    
  • Terminals 21 - 22 (NC): Wire into your auxiliary standby, interlock, or monitoring circuit.
• Terminals 13 - 14 (NO): Wire into your primary motor coil or run enable circuit.
• Terminals 21 - 22 (NC): Wire into your auxiliary standby, interlock, or monitoring circuit.
• Wire LED Block (X1 - X2): Connect your 24V AC/DC supply leads to the central light module terminals marked X1 (+) and X2 (-).
