The SCHNEIDER ELECTRIC XB4BV34 is a red-lens incandescent pilot light designed for panel-mount indicator applications in industrial and commercial control systems. Rated for 110-120 VAC at 50/60 Hz, it uses a screw clamp connector for secure wiring termination and features a 30mm overall diameter with a 22mm panel cutout. The round lens delivers clear visual status indication. Built to withstand demanding environments, the XB4BV34 carries a NEMA 4X rating along with UL 508 listing and compliance with EN/IEC 60947-5-1, making it suitable for both indoor and wet or wash-down locations. Licensed electricians and industrial control panel builders are the primary installers of this component.
The XB4BV34 is used in industrial control panels, machine operator stations, and commercial electrical enclosures where a durable, standards-compliant pilot light is required. Its NEMA 4X and vibration-resistant construction makes it a practical choice for manufacturing environments, process equipment, and pump or motor control panels. The 30mm body fits standard 22mm panel cutouts common across control panel hardware in both new construction and retrofit applications.
Designed as an OEM-style panel indicator for industrial control enclosures requiring a 22mm panel cutout and a 30mm pilot light body with screw clamp termination.
Installation should be performed by a qualified electrician in accordance with NEC and local electrical codes. De-energize the control panel completely before mounting or wiring the pilot light. Use the screw clamp connector with an appropriate screwdriver; do not overtighten terminals. Verify the panel cutout diameter is 22mm before mounting to ensure a proper seal and NEMA 4X rating is maintained.
