Relay Sockets & Fixings NGR VOLT SCALER 100-2KV

Dual Overcurrent Relay. 230V 5A. The T2400 consists of two combined over current relays, intended for protection, or monitoring of generators, power transmissions and consumer supply. A typical application for protection of a generator is for one of the over current functions to trip the generator breaker and the other over current function to trip a nonessential service. Both over current functions could be used to trip 2 levels of nonessential load. The relay detects the highest of the 3 input currents and, on exceeding the preset values, output relays will be activated after preset time delays.

Short Circuit Relay. 400/450V 5A. The T2300 is intended for protection of generators, power transmissions and consumers against damage caused through short circuit by tripping the circuit breaker. The relay detects the highest of the 3 input currents and on exceeding the preset values, an output relay will be activated after a preset time delay or momentarily (0.1 second).

Ovrcurent & Short Circuit Rely400/450V1A. The T2500 is a high quality Over-Current and Short-Circuit relay intended for protection against thermal damage and faults caused by excessive currents. The T2500 can be used to protect generators, power transmission lines and various types of consumer supplies. The T2500 monitors two levels of current and trips the circuit breaker when one of these two levels has been exceeded continuously for a time period (defined by an adjustable delay). The T2500 will support the connection of up to three phases, but will react on the largest of these three measurements. The current measurements are done through external current transformers (CTs) – typically with a secondary current of 5A. The Over-Current function can be adjusted to trip within the range of 0.5 to 1.4 x I (input current). The delay of the Over-Current function can be set between 3 to 30 seconds. The Short-Circuit function operates within the range of 1.0 to 4.0 x I. The Short-Circuit delay can be set between 0.1 and 1 second. The T2500 will react on the highest of the three input currents. The Pick-up LED will ignite as soon as the level is exceeded, while the relay is activated only after the delay has passed.
