Quick PRD40r 3P+N Surge Protection Device

The Quick PRD40r 3P+N surge protector from Schneider Electric, reference A9L16294, is an advanced solution for protecting residential, commercial, and industrial electrical installations against transient overvoltages. This device is designed to manage indirect overvoltages generated by atmospheric discharges or disturbances in the electrical network, providing reliable protection in environments with a high risk of voltage variations.

This model, part of the Acti9 range, is a Type 2 surge protector with a maximum discharge capacity (Imax) of 40 kA, making it an ideal choice for main distribution boards in buildings with demanding safety requirements. Its self-protected design includes an integrated circuit breaker with a breaking capacity of 20 kA, which automatically disconnects the device when it reaches the end of its service life, thus ensuring continuous protection without the need for immediate manual intervention.

The Quick PRD40r features a remote signaling system that indicates when it is necessary to replace the cartridges via a signaling contact, allowing for remote monitoring for more efficient management of the electrical system. Additionally, the device is pre-wired to facilitate the quick replacement of damaged cartridges, minimizing downtime and ensuring uninterrupted protection.

This device is designed for easy installation and maintenance. It incorporates tunnel-type terminals that accommodate rigid cables from 2.5 to 35 mm² and flexible cables from 2.5 to 25 mm², with a recommended tightening torque of 2.5 N.m. The ability to quickly replace damaged cartridges and its local and remote signaling ensure effective protection and simplified maintenance.

Additional benefits:

• Remote monitoring: The device includes a remote signaling contact that alerts when it is necessary to replace the protection cartridge, facilitating preventive maintenance and reducing the risk of protection failure.
• Continuous protection: Thanks to its integrated circuit breaker, the device automatically disconnects when it reaches the end of its service life, eliminating the risk of continuing to operate without protection.
• Durability and reliability: This surge protector is designed to operate in a temperature range of -25 °C to +60 °C, making it suitable for a variety of demanding environmental conditions, and its IP20 protection rating ensures its durability in safe environments.

The Quick PRD40r 3P+N is an essential solution for protecting critical installations from voltage spikes and transient overvoltages. Its discharge capacity of up to 40 kA and advanced protection technology make it an indispensable tool for ensuring the safety of electrical installations in homes and large buildings.
