Industrial ZB4BVBG1 Light Block Assembly

ZB4BVBG1 is a complete body light block assembly for Schneider Electric’s Harmony XB4 modular pushbutton family. It features a metal housing with a body fixing collar (Zamak), a universal LED light source, and a white signaling LED designed for steady operation. Rated for 24–120 V AC/DC at 50/60 Hz, it provides integrated illumination within Harmony XB4 operators and mounts with the included body/fixing collar. The compact module measures 30 mm wide (1.2 in), 47 mm high (1.9 in), and 37 mm deep (1.5 in) and weighs about 0.054 kg (0.119 lb). Wiring uses screw clamp terminals that accept up to 2 × 1.5 mm² with cable ends, or at least 1 × 0.22 mm² without cable ends. Electrical resilience includes an insulation voltage rating of 600 V, a surge withstand of 1 kV (IEC 61000-4-5), and a service life specification of up to 100,000 hours at rated voltage and 25 °C. With a steady signaling type and universal LED, ZB4BVBG1 is the dedicated lighting block for Harmony XB4 assemblies, offering reliable indicator functionality in industrial control panels.
