Adjustable thermal and magnetic trip is designed for precise coordination with diverse load profiles, reducing nuisance trips while preserving safe shutdowns in industrial panels. This translates to lower unplanned downtime and improved process uptime in manufacturing lines and packaging equipment. The 15-20 A OL setting range paired with a 350 A delayed short-circuit release enables tailored protection for motor drives and conveyors, improving equipment longevity and energy management. The device’s 690 Vac / 750 Vdc rating supports mixed AC and DC systems common in modern automation architectures, enabling a single protective device to cover multiple subsystems and reducing parts variety in maintenance stock. Built on the NZM2 frame, it delivers a compact footprint that frees panel real estate and simplifies retrofits in upgraded control cabinets. Front screw connections streamline wiring during installation and service, speeding commissioning and reducing field labor costs. Accessories like rocker lever and motor drive options enhance operator control and integration with MCCs, shortening downtime during starts and stops.
