Product description
The GEYA GYL9 4P 40A 30mA Type A three-phase residual current device (RCD) is a key protective component designed to safeguard health and life against electric shock in the event of direct or indirect contact with live parts. At the same time, it effectively prevents the risk of fire caused by fault currents flowing to earth in three-phase circuits.
This residual current device belongs to sensitivity class Type A with a sensitivity of 30 mA, which is required for personal protection. Unlike basic Type AC residual current devices, it can reliably respond not only to purely alternating sinusoidal fault currents, but also to pulsating direct currents. These are generated in modern electrical installations by switched-mode power supplies, frequency converters, heat pumps, induction hobs and PV inverters.
The device does not contain integrated overcurrent protection (it is not a circuit breaker); therefore, it must be protected upstream in the circuit by a suitable circuit breaker or fuse with a rated current of up to 40 A.
MAIN ADVANTAGES AND APPLICATIONS: Detection of alternating and pulsating DC currents (Type A): Ensures reliable protection of modern electrical installations equipped with appliances featuring control electronics.
High level of safety for people and property: A sensitivity of 30 mA ensures that the circuit is disconnected in good time should a dangerous leakage current occur, thereby protecting against electric shock.
Fire protection: Prevents prolonged leakage currents, which can cause wiring to overheat and result in a fire.
4P (three-phase) version: Designed for the complete protection of three-phase circuits (L1, L2, L3 + N) in detached houses, workshops and commercial premises.
Test button (TEST): Allows for regular manual checks of the circuit breaker’s correct mechanical and electrical functionality.
Visual status indicator: A clear viewing window on the front panel indicates the operating status and position of the contacts (on / off).
Compatibility and easy installation: Designed for mounting on a standard DIN rail (TH35) in domestic and commercial distribution boards (width: 4 modules / 72 mm).
