Nader NDB6AZ-63H Circuit Breaker

Overview

A miniature circuit breaker designed for the telecom machine room and the communication cabinet rather than adapted from a building product. It works on DC up to 80V at 4A to 63A, and provides isolation, short circuit and overload protection for the cabinet, the room or the downstream user line.

The body is a single rack unit where the previous generation took three, which is the practical difference on a crowded DC distribution panel. Nader cite 63 patents in the series, and the opening and closing button and the connection method were both reworked for safer, faster work in a live cabinet.
