The ZB4BZ102 is a complete body and contact assembly designed for use with Harmony XB4 22mm push buttons. It is a single unit composed of a body and a Zamak fixing collar, equipped with one slow-break normally closed (1 NC) contact. The contacts are made from a silver alloy (Ag/Ni) and connect via screw clamp terminals. Key electrical characteristics include a conventional free air thermal current of 10A, a rated insulation voltage of 600V, and a rated impulse withstand voltage of 6kV. With a high mechanical durability of 5,000,000 cycles and an operating temperature range of -40 to 70°C, this contact block is a robust solution for industrial control applications.
