Schneider Electric Harmony Series Light Block, White Light

This light Block provides a panel-mounted signalling solution with an integrated LED illumination for 22mm control heads, designed to be mounted at the rear of an enclosure and powered from a 230 to 240V supply. It is intended for industrial control and instrumentation environments requiring a compact, steady white indicator.

• Low current draw of 14 mA reduces control-circuit load
• Wide supply tolerance 195 to 264V AC for voltage variation resilience
• Long rated service life of 100,000 h at 25 °C for reduced maintenance
• Screw clamp terminals accept up to 2x1.5mm² for secure connections
• Operating temperature range −40 °C to 70 °C suits harsh environments
• IP20 protection and vibration resistance for panel-mounted stability

• Suitable for automation panels requiring steady white status indication
• Ideal for retrofit of 22mm control and signalling units
• Used with industrial enclosures needing rear-mounted illumination
• Can be used for electrical control racks in manufacturing plants

It uses screw clamp terminals that accept up to 2x1.5mm² with suitable ferrules or a single conductor ≥0.22mm² without ferrules, tightened to 0.8 to 1.2 N·m.

It withstands fast transients to 2 kV, electromagnetic fields to 10 V/m and electrostatic discharge to 6 kV on contact and 8 kV in air.

The device resists vibration at 5 g n (12 to 500 Hz) and shock up to 50 g n for short durations, meeting relevant IEC test methods.

In EU markets it must be collected separately under WEEE regulations and must not be discarded with general waste.
