Three-phase protector/measuring apparatus OVD 706KT

Presented in casing for Standard DIN 35mm rail (EN 50 022), it is a compact device controlled by a 16 Bit microcomputer, highly stable due to the inclusion of a double state of process watchdog. It withstands permanent and transitory peak surges, as well as low voltage. It can protect multiple, single-phase or three-phase lines, of up to 63A.
It provides diverse measurements and protections:

Differential protection with very high speed cut-off
Protection against peak surge via very high speed physical cut-off
Protection against low voltage
RMS value measurement of V, I ∆ n.

Moreover, constant surveillance of the power input enables an Intelligent Automatic Reset (conditioned). In other words, it resets only on re-establishing normality in the supply. Certain models / versions have Remote Control input and output.
