The ZB5AZ103: Single contact block for the Harmony XB5 family. 2 NO slow-break silver-alloy contacts in a complete body/contact assembly — no separate operator head to buy. The plastic fixing collar accepts any standard XB5 actuator. Screw-clamp terminals take 0.22 mm² wire, torqued to 0.8–1.2 N·m. Rated for 3 A at 240 V in AC-15 duty (A600 utilization category), with a conventional free-air thermal current of 10 A. Mechanical durability runs past 10 million cycles, and electrical durability hits 1 million at the rated switching levels. Carries UL 508, IEC 60947-1, CSA C22.2 No 14, IEC 60947-5-1, JIS C8201-5-1, and JIS C8201-1 approvals. Vibration tested to 5 gn (2–500 Hz), shock rated to 30 gn half sine. Ambient temperature range –40 to 70 °C.
