Schneider Electric Acti9 iDT40 Series Residual Current Device 25A 3-Pole 300mA DIN Rail A9Y13725

The Schneider Electric Acti9 iDT40 Series Residual Current Device, model A9Y13725, is an advanced protection solution designed for safeguarding circuits against earth leakage currents in industrial, commercial, and infrastructure applications. Rated for 25A current and featuring a trip sensitivity of 300mA, this three-pole RCCB is engineered to ensure rapid detection and disconnection in the event of fault currents, thereby enhancing overall safety of installations.

This device is specifically constructed for DIN rail mounting, accommodating standardized electrical panel configurations and promoting easy installation or replacement. Its robust construction incorporates a reliable thermal magnetic tripping mechanism, providing both thermal response to sustained overloads and electromagnetic response to short circuits. The toggle switch reset actuator ensures convenient and safe restoration of power after any trip event, supporting hassle-free maintenance and minimized downtime.

The iDT40 series is renowned for its utility in demanding electrical systems where consistent protection against earth leakage is critical. The device’s 3-pole configuration makes it suitable for three-phase power systems, frequently found in manufacturing plants, process industries, commercial complexes, and HVAC distribution panels. The RCCB conforms to CE and EN/IEC 61009-2-1 standards, making it a reliable option for projects that demand compliance with international quality and safety requirements.

Featuring compact dimensions (91mm height, 108mm width, 74mm depth), the A9Y13725 model optimizes valuable distribution board space while maintaining high performance. Tunnel-type terminals further streamline connection and ensure secure wiring. The AC-type earth leakage protection functionality is designed for common electrical loads and delivers instantaneous break time, offering immediate protection upon detecting residual currents.

The device comes equipped with a 4kV impulse withstand voltage, ensuring resilience against transient overvoltages often present in industrial installations. Its application is not limited to new systems - this RCCB can be retrofitted into existing setups where greater electrical safety is required.

Suitable for use in: industrial electrical panels, commercial building distribution, process automation centers, HVAC system controls, infrastructure projects, and wherever three-phase, high-reliability earth leakage protection is mandatory.
