MS3320 SERIES 4310 Ambient Temperature-Compensated Miniature Circuit Breaker Performance Data The space-qualified product utilizes the same design as the 4310. Miniature Size -- High Performance High Interrupting Capacity: Interrupts 6,000-ampere fault at 28V, DC; up to 3,500-ampere fault at 120V, 400 Hz., AC (ampere rating dependent) Temperature-Compensated: Ambient-temperature-compensated from -55C to +121C Vibration Resistance: Vibration resistance and mechanical life exceed mil specs -- including random vibration Qualified: To MS3320 of Mil-C-5809. Meets performance specification of MS14105 of MIL-C-5809 The MP lightweight, single-phase circuit breaker, Series 4310, allows high density packaging for all aircraft and aerospace needs. The 4310 series reflects the latest advancements in circuit breaker design... plus the proven features of previous MP models (e.g., self-wiping contacts). Tight tolerances in design and stringent manufacturing standards are key factors in the reliable operation of the 4310 under severe environmental conditions of high temperature, high humidity, extreme vibration, and shock. It is also fungus- and corrosion-proof. 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 a 7/16, 15/32, and metric mounting sleeves. Many versions of different terminals, barriers, and hardware are current production items. Several different actuator options provide our customers with additional flexibility in their designs.
