Function CBS-1600A Multi-Channel Earth Leakage Monitoring Relay — 16 Channels, Type A, 30–3000 mA, RS-485 Modbus

The CBS-1600A monitors sixteen circuits for earth leakage from a single three-module-wide unit, each channel through its own external toroidal transformer of the Circutor WGC range. Circutor's own designation for it is "multi-channel leakage current monitoring relay, type A". Every channel is measured and displayed independently, so the unit answers the question a single relay cannot: not merely that the installation is leaking, but which of the sixteen outgoing ways is doing it. Sensitivity is adjustable from 30 to 3000 mA. Two change-over output relays provide the alarm and the pre-alarm, and an integrated RS-485 port speaks Modbus/RTU so the readings can be logged continuously rather than read off the front panel after a trip — the basis of preventive rather than reactive maintenance. It is suitable for TT, TN and IT systems and runs from 230 V AC. It is a type A device: it responds to sinusoidal AC residual currents and to pulsating DC residual currents. Circutor specify it as superimmunised, with high-frequency filtering and true RMS (TRMS) measurement, so that the harmonic leakage normal in an installation full of switch-mode loads does not read as a fault. Manufactured by Circutor (Spain) and supplied under the Function brand; the Circutor catalogue reference is CBS-1600A. This item is listed in the Norwegian trade under the supplier shorthand "CBS-16A", which is not a Circutor model code — the manufacturer designation is CBS-1600A. Supplied by cBallast on quote-to-invoice terms; lead time and freight are quoted per RFQ against the destination Incoterm.
