Description
The T3200 Insulation-Monitoring Relay is designed for
continuous insulation monitoring on three-phase insulated
networks on board ships. The relay continuously monitors
two systems galvanically separated from each other, e.g.
the busbar and the lighting system, or two busbar systems.
The unit features two output relays for alarm purposes and
two analog outputs for instrument reading. Instruments are
available from Littelfuse Selco as standard-sized switchboard
instruments. The T3200 carries the CE label and has been
approved by major marine classification societies.
