Description

This component detects leakage currents in electrical systems and disconnects the circuit to prevent harm. It provides residual current protection for devices and humans, safeguarding against electric shock and fire hazards caused by earth faults. **Electrical Specifications:** - Rated current capacity: 40A. - Residual current sensitivity: 300mA (non-adjustable). - Operating voltage range: Typically compatible with standard AC supply systems, dependent on local standards. - Frequency response designed for alternating current (type A) – also monitors pulsating DC residual currents. **Physical Design & Installation Parameters:** - Four-pole design suitable for three-phase or multi-line systems with neutral. - Mounted via DIN rail conforming to typical modular enclosure designs. - Standard connection terminals include screw-type clamps; requires appropriate torque during installation. **Technical Notes / Limitations:** - Not intended for overload or short-circuit protection; must pair with an adequate circuit breaker. - Type A devices do not detect smooth DC residual currents that exceed specified thresholds. - Requires regular testing using external equipment or integrated test function if available.
