Frequently asked questions

Frequently asked questions — TDP-2 voltage / current monitoring relays

What does the TDP-2 monitor?

Voltage and current, both shown on the front display. It trips on overvoltage, undervoltage or overcurrent, then reconnects automatically after a time delay.

Which TDP-2 models are available?

TDP-2-1, single-phase 220 V, in 40 and 63 A with a 1NO output contact; TDP-2-3, three-phase 380 V, in 63 and 80 A with a 3NO output contact.

What are the TDP-2 setting ranges?

Overvoltage 230 – 300 V (220 V) or 390 – 500 V (380 V); undervoltage 140 – 210 V or 260 – 370 V; tripping delay 0.1 – 30 s; reconnection 1 – 600 s (TDP2-1) or 1 – 500 s (TDP2-3); overcurrent from 1 A up to In.
