Schneider Electric Residual Current Circuit Breaker with Overload Protection, 16A Current Rating, 3-Pole, 30 mA Trip A9DB3716

Schneider Electric A9DB3716 Residual Current Circuit Breaker with Overload Protection is a high-performance device designed to protect electrical circuits by combining residual current and overload protection in a single unit. Rated at 16A with a 3-pole configuration and 30 mA trip sensitivity, this breaker ensures safety against earth leakage currents and overload conditions, making it ideal for residential and light commercial electrical installations.

Featuring the Acti9 iDD40N series technology, the unit employs a thermal magnetic trip unit mechanism providing superior protection against short circuits and overloads while preventing nuisance tripping with instantaneous earth-leakage protection time delays. The toggle switch actuator enables easy manual control for switching ON/OFF while clearly indicating trip status.

The device’s compact dimensions - 90 mm width, 93 mm height, and 73 mm depth - allow it to be easily mounted on standard DIN rails within electrical panels. Designed to operate reliably within ambient temperatures ranging from -5 to 60 °C and relative humidity levels up to 95%, it exhibits excellent electrical durability rated at 20,000 operating cycles. Additionally, the breaker is padlockable, adding an extra layer of security during maintenance or downtime.

Constructed under stringent compliance with EN/IEC 60947-2 and RoHS directives, the circuit breaker is ideal for residential overcurrent and earth-leakage protection applications. Its breaking capacity of 10 kA and impulse withstand voltage of 4 kV further ensure resilience in demanding electrical environments.

Offers 3-pole configuration ensuring secure multi-phase protection. Equipped with 30 mA trip sensitivity for enhanced earth-leakage safety. Features a toggle switch reset actuator for easy ON/OFF and trip indication. Mounts conveniently on standard DIN rails for seamless installation.

Complies with EN/IEC 60947-2 and RoHS standards for quality assurance. Supports rated AC voltage up to 400 V AC for versatile applications. Built with thermal magnetic tripping mechanisms for overload and short circuit protection.
