Overview
PROTECTION Type VTT 11, 12 Definite Time Delay Relay VTT is a static time delay relay which is particularly suitable for applications requiring large number of operations and consistent accuracy with little or no maintenance over long periods.
It is also commonly used in industrial processes.
Features • Consistent accuracy • Reliability • Low burden • Reduced maintenance • Immunity to transients and surges; withstands 5 kv impulse voltage test • Relays with heavy-duty magnetic blow-out contacts also available Description A stabilised voltage is applied to a resistance/capacitance circuit.
The potential developed across the capacitor is applied to a transistor switching circuit ...
