The ZB4BZ1016P is a complete body and contact assembly designed for the Harmony XB4 series, incorporating a single contact block and a Zamak fixing collar. It provides a single normally open (1NO) contact with a slow-break operation and gold-flashed contacts for high reliability. Key electrical characteristics include a conventional free air thermal current of 10 A, a rated insulation voltage of 250 V, and a rated impulse withstand voltage of 4 kV. This assembly is engineered for high durability, with a mechanical life of 5,000,000 cycles and an electrical life of 1,000,000 cycles under specified AC-15 loads. With an IP20 rating and compliance with IEC, UL, and CSA standards, it is a robust solution for industrial control applications requiring reliable switching.
