Amphenol 300CB08 Circuit Breaker Panel


The Amphenol Network Solutions 300CB08/nrg300CB08 are 325A dual-feed 8/8 position circuit breaker panels featuring ±12/±24/±48V operating voltages to serve both legacy and "next-gen" network applications. Engineered into a standard 1RU footprint, each circuit supports up to 60A breakers in each position, providing ample capacity front view for distribution to a broad range of components. Advanced circuit level monitoring features are available as an option. The panel is available in standard terminal block outputs or connectorized outputs. This platform provides front access to circuit breakers with alarm on/off switch configuration for uninstalled breaker locations. Also featured are front LED indicators for power/breaker alarms and monitoring status, and rear connections for form C relay alarms (and optional nrgSMART controller connections). Each of the 325A feeds provide power for up to eight output positions. Field replaceable circuit breakers are available from 5A to 60A per position. The front of the panel features a face plate designed to protect against unintended breaker on or off switching. The panel supports universal voltages (±12VDC to ±48VDC).

Features & Benefits
