The ZBE101 is an add-on contact block designed for the Harmony XB4 and XB5 series of 22mm push buttons. It provides a single normally open (1 NO) contact with slow-break operation and connects via screw clamp terminals. This block features a rated insulation voltage of 600V, a conventional free air thermal current of 10A, and a rated impulse withstand voltage of 6 kV. The contacts are made from a silver alloy (Ag/Ni) and are protected against short-circuits by a 10A gG cartridge fuse. With a high mechanical durability of 10,000,000 cycles and an operating temperature range of -40°C to 70°C, this component is ideal for reliable use in industrial control applications.
