Circuit Breaker Enclosures
The NA1200AWK is an old obsolete circuit breaker enclosure that is NO longer available.
The NA1200AWK circuit breaker enclosure was not an externally operable device. The enclosure door must be opened to operate the enclosed NAL, NHL or NXL breaker. The enclosure is equipped with a vault handle on the enclosure door, which is lockable. This vault handle locks the enclosure door closed only and does not perform any locking function of the Circuit Breaker. However, a handle padlock attachment, HPANE, was included with the NA1200AWK enclosure for field installation on the Circuit Breaker, if required, for padlocking the circuit breaker ON or OFF.
