TELAIO FISSO 4P

This is a chassis for 4 poles Compact NS and Masterpact NT drawout circuit breakers and switch disconnectors. This chassis is adapted to drawout Compact NS 1600 N/H and Compact NS 630b to 1000 L circuit breakers. This chassis is adapted to drawout Compact NS 1600 NA switch disconnectors. This chassis is adapted to drawout Masterpact NT 16 H1/H2 and Masterpact NT 06 to 10 L1 circuit breakers. This chassis is adapted to drawout Masterpact 16 HA switch disconnectors. This multifunctional chassis is particularly suited for incoming devices. It allows the device connection and disconnection through a door, using a crank that can be stored in the chassis. It indicates three positions of the device (connected, test and disconnected) that are indicated locally by a position indicator or remotely by a carriage switch. It enables circuit breaker ON/OFF commands through a switchboard front panel. There are several extensive locking possibilities of the chassis. A mismatch protection ensures that a circuit breaker is installed only in a chassis with compatible characteristics. This chassis is for 3 poles devices.
