This lightweight, miniature, three-phase circuit breaker, Series 4330, reflects the latest advancements in circuit breaker design, incorporating self-wiping contacts, tight tolerances in design, and stringent manufacturing standards. It is fungus- proof and highly resistant to corrosion. The trip-free thermal mechanism avoids nuisance trips (even during temporary surges of starting loads) under ambient temperatures ranging from -55°C to +71°C. Calibration integrity is maintained through wide variations in ambient temperature and altitude, making this circuit breaker ideal for applications where temperature is not controlled. Multiple Options This series is available in many optional configurations
