nrgSMART 600A Load Center panels are available with dual-feed 10/10 or single-feed 20 circuit breaker positions to accommodate bullet-style breakers or fuse holders. The panels feature -48V operating voltage to fit in legacy and “next-gen” network applications, with advanced circuit level monitoring features engineered into a compact 2RU footprint.

| * Telect suggests you avoid using different types of circuit breakers in the same load center. Alarm contacts may vary among interrupter manufacturers and may incapacitate the alarm system.
** Circuit breakers for this load center are designed and manufactured by Airpax Corporation and Carling Industries to meet Telect’s symmetrical pin
specifications. Order circuit breakers only from Telect.
