About the DS440S-320/G

The DS440S-320/G is the remote-signalling version of the CITEL DS440-320/G: the same compact 3-phase+N Type 2 surge protector in the 3+1 arrangement (three varistor phase modules plus an N-PE gas-tube module, for TT and TN-S networks), with a changeover contact that tells your building management system or alarm panel when a module has disconnected. Spare modules are the DSM440-320/G (phase) and DSM440-320/GPE (N-PE).

About the DS440 range

The DS440 Type 2 surge protectors are compact devices designed to protect 3-phase+N networks at the main switchboard. They provide a common or common/differential mode protection. This SPD is based on high energy varistor equipped with thermal disconnectors and failure indicator to comply with standards. The DS440 is DIN rail compatible and is built with a plug-in module and fixed base, which allows an easy and fast maintenance.
