PART 1. INTRODUCTION
General Information
The Navy Type AQB-L400 or AQB-LL400 circuit
breakers (Figure 1-1), when supplied with a factory
installed Eaton AQB-L400 Adapter Kit (Figures 1-2 and
1-3), can be installed directly into Navy Type AQB-LF400
applications. This combination of an AQB-L400/LL400
circuit breaker and the Eaton Adapter Kit pro­vides a
direct one to one current limiting type L400 circuit
breaker replacement for an already installed fused type
LF400 circuit breaker. Existing AQB-L400/LL400 circuit
breakers in the field (manufactured prior to August, 1992)
may need a factory modification to accept the Adapter
Kit. Contact Eaton for details, if there are any questions.
