The Resi9 2P 40A circuit breaker from Schneider Electric, reference R9F12240, is a reliable electrical protection device, designed to ensure the protection of both individual and collective residential electrical installations. This miniature circuit breaker (MCB) effectively combines protection against short circuits and overloads, providing a complete and safe solution for electrical circuits in homes and small buildings.
The Resi9 circuit breaker is equipped with 2 protected poles and has a rated current of 40A, making it an ideal choice for medium-sized circuits. Its short-circuit breaking capacity reaches 6000A at 400VAC, ensuring installation safety in the event of severe faults. This level of protection meets the requirements of the international standard EN/IEC 60898-1, ensuring the breaker withstands both overloads and unexpected current surges.
The breaker's tripping technology is thermal-magnetic, allowing it to react quickly to current variations. The C tripping curve is the most common in residential applications, making it a suitable option for protecting sensitive devices against transient overloads or short circuits.
This circuit breaker is compatible with standard DIN rail installation, making it suitable for integration into modular electrical panels. The compact design of this model, with a width of 4 steps of 9 mm, allows for easy installation even in confined spaces.
The Resi9 2P 40A is designed to be extremely durable, with a mechanical endurance of up to 20,000 cycles and an electrical endurance of up to 10,000 cycles. This ensures that the breaker will maintain reliable performance over time, even in applications requiring frequent operations.
This circuit breaker offers a high level of protection for electrical circuits, without the need for additional earth leakage protection. The device provides a clear on and off indication via a control lever and features a protection rating of IP20 at the terminals and IP40 when installed inside a modular cabinet, ensuring greater safety in installations.
This Resi9 2P 40A circuit breaker from Schneider Electric is a robust and reliable solution for protecting electrical circuits in residential buildings, ensuring service continuity and safety against overloads and short circuits. Its easy installation and durable design make it an ideal choice for any modern electrical installation.
