The space-qualified product utilizes the same internal design. Three-Phase Protection Qualified To MS14154 of MIL-C-5809. Lightweight Weighs 68 grams maximum (0.15 lbs). Vibration Resistance Vibration resistance and mechanical life exceed MIL Specs — including random vibration. Miniature Size — High Performance 19.8mm, 46.7mm, 35.0mm behind panel depth. Temperature-Compensated Ambient-temperature-compensated from -55°C to +71°C. Note: higher operating ranges are available. Performance Rated Circuit Breaker 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 fungusproof 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. It is presently being manufactured with 7/16, 15/32 and metric mounting sleeves. Many versions of different terminals, barriers, and hardware are current production items. Several different button options provide our customers with additional flexibility.
