Plug-in The record plus plug-in version allows quick, safe and easy interchange of breakers. It is made up of a "standard" fixed-front-connection breaker, a set of plugs, a trip mechanism fitted to the breaker and a monoblock base into which the breaker is plugged. When the breaker is removed from the plug-in base it trips automatically (main contacts open) before the plug-in contact in the base are disconnected. The breaker can be operated (closed and opened) when removed from the plug-in base. On attempted insertion of a breaker in the "ON" position into the plug-in base, the Record Plus breaker trips before the plug-in contacts in the base are connected. The Record Plus plug-in version is available for :
FD frame sizes FD63/160 (maximum 125 Amps)
FE frame sizes FE160/250 (maximum 250 Amps)
FG frame sizes FG400/630 (maximum 630 Amps)
FD and FE frame sizes equipped with "bottom mounted RCD unit" can also be transformed into the plug-in version. The mobile part of the plug-in version remains the same (plugs and trip mechanism do not change). The fixed plug-in base is of a different, elongated type and has a separate catalogue number.
