Residual current transformers, 105 mm Ø (inner), 0,5 A, Type A, AC

Residual current transformers are used in combination with evaluation units to monitor and protect electric circuits. Transformers form series MFIW combine with the MFR evaluation unit to form a modular residual current device (MRCD) as per VDE 0660-101. Residual current transformers with characteristic A detect sinusoidal AC currents as well as pulsating DC residual currents. The transformer covers all of the active conductors leading to the consumers and uses its output signal to illustrate the time curve of the sum of all conductor currents flowing through it. Its output signal is proportional to the residual current, which flows back to the earthing point of the supply mains via the protective earth conductor in the case of an insulation fault or via the earth.

suitable for detecting type A and AC residual currents as well as pulsating DC residual currents, tightly stacked through-holes allow good adjustment to the cable to be monitored, rated residual current is determined by the selected transformer, terminals up to 4 mm²

The devices are mounted on stable substrata using the supplied mounting brackets.any installation position

Transformers from series MFIW are used in combination with series MFR modular residual current devices.

The through-hole should be filled as much as possible with the cable to be monitored, so that it is centred in the transformer. Faulty tripping caused by the transformer being asymmetrical can therefore be avoided.
