Residual Current Devices, Sensitivity (mA) 30, Rated Current (A) 63, 4-Pole (3-Pole + Neutral), Ut min = 110V

Residual Current Devices 1492-RCDA • 25…80 A residual current devices • 30 mA sensitivity devices for personnel protection • Reversible line and load connections • Suitable for protection against AC and pulsating DC (rectified AC) earth leakage current • Dual terminals allow a more secure connection of two wires, or both a wire and bus bar • By detecting small leakage currents and disconnecting all ungrounded connectors quickly, RCDs can prevent injury to exposed personnel and damage to equipment.
