Transient and Permanent Surge Protector IGA Resi9 Combi 1P+N 40 A

The Schneider Electric Resi9 Combi 1P+N 40 A transient and permanent surge protector (reference R9L20640) is an advanced protection device that integrates multiple functionalities to ensure the safety of electrical installations in residential and commercial environments. This model is capable of protecting against both short circuits and overloads as well as transient surges (caused by lightning or network operations) and permanent surges, making it a comprehensive solution for the protection of sensitive electrical and electronic equipment.

Main features:

• Combined protection: The Resi9 Combi provides protection against short circuits and overloads, ensuring that electrical circuits are not damaged due to excessive currents. Additionally, it protects against transient surges (e.g., electrical discharges or network operations) and permanent surges (due to failures in the electrical distribution network). This makes it a versatile and comprehensive device that protects the entire electrical installation from the harmful effects of these events.

• Automatic tripping unit: This device includes a tripping unit that automatically disconnects the power supply when it detects a permanent surge, ensuring the safety of connected equipment. This function is essential to prevent damage to appliances, computers, televisions, and other electronic devices in the event of an unexpected voltage increase.

• Ideal for electric vehicle charging points and solar panels: Surge protection for both permanent and transient surges is mandatory in many cases, especially in installations of electric vehicle charging points and solar panel systems. The Resi9 Combi meets these requirements, offering complete protection for new sustainable energy installations.

Technical specifications:

• Rated current: 40 A, making it suitable for a wide range of residential and commercial electrical installations.
• Number of poles: The device has a 1P+N configuration, meaning it protects both the phase and neutral, providing complete protection for the electrical system.
• Breaking capacity: The breaker has a breaking capacity of 6000 A according to the EN/IEC 60898-1 standard, ensuring it can safely handle short-circuit situations without compromising the electrical installation.
• Type C tripping curve: The device is designed with a type C tripping curve, suitable for applications where there are moderate inductive loads, such as motors or transformers.

Advanced functionalities:

• Fast response time: In the event of a transient surge, the device acts in less than 25 nanoseconds, minimising the exposure time of equipment to dangerous voltage spikes and ensuring immediate protection.

• Mechanical and electrical durability: The Resi9 Combi is designed to withstand up to 20,000 mechanical cycles and 10,000 electrical cycles, ensuring long service life and reliable operation in any installation.

• DIN rail mounting: This device is designed to be easily mounted on a standard DIN rail, facilitating its integration into electrical distribution boards.

Connectivity and safety:

• Connections: The device's connections are designed to handle rigid cables from 1.5 to 25 mm² and flexible cables up to 16 mm², ensuring a secure and reliable connection. Additionally, the tunnel-type terminals allow a tightening torque of up to 3.5 N.m, ensuring a firm and stable connection.

• Standards and certifications: The Resi9 Combi complies with EN/IEC 60898-1 standards and is certified by CE and AENOR, guaranteeing its safety and compliance with international standards. Additionally, it carries quality labels certifying its robustness and reliability in any installation.

Applications and benefits:

• Protection for residential and commercial environments: This device is ideal for installation in homes, offices, and small businesses, where it is essential to protect both electrical systems and connected equipment from potential electrical failures or surges caused by external factors.

• Protection of sensitive electronic devices: The Resi9 Combi is specifically designed to protect sensitive electronic devices such as computers, televisions, modems, and hi-fi equipment, ensuring that these devices are not damaged due to fluctuations in the electrical network.

• Energy efficiency and enhanced safety: By combining multiple functionalities in a single device, this breaker enhances circuit self-protection, reducing costs and installation complexity. Additionally, the integration of overload and surge protection in a single unit ensures greater efficiency and safety throughout the installation.
