Application:
CAL2-63 RCCB's residual current devices provices the functions of isolation, switching and earth leakage protection of electrical circuits. They have a residual current operated electromechanical release which operates without and auxiliary sourced of supply to open a circuit auto-matically in the case of an earth leakage fult between phase and earth greater than or equal to a threshold of 10ma, 30ma, 100ma, 300ma, 500ma.

Construction and Feature
. Provide protection against earth fault/leakage current and function of isolation
. High short-circuit current withstand capacity
. Contact position indication
. Equipped with finger protected connection terminals
. Fire resistant plastic parts endures abnormal hearing and strong impact
. Automatically disconnect the circuit when earth fault/leakage current occurs and exceeds the rated sensitivity
. Independent of power supply and line voltage, and free from external interference voltage fluctuation
