Featuring a C curve tripping characteristic, this MCB is ideal for applications with moderate inrush currents such as lighting circuits and small motor loads.

It supports a rated current of 40A, so allowing it to effectively manage higher loads without unnecessary interruptions.

The thermal-magnetic trip unit guarantees accurate and dependable disconnection during abnormal operating conditions,

so offering optimum performance under pressure.

High Short Circuit Breaking Capacity

Engineered to handle extreme conditions, Schneider R9F32340 offers a rated short-circuit breaking capacity (Icn) of 4500A at 400V AC, compliant with IEC/EN 60898-1 standards.

This makes it exceptionally suitable for low-voltage distribution networks in residential environments. With a limitation class 3,

the MCB significantly reduces let-through energy, helping to protect downstream equipment from damage.

Long-lasting Durability and Mechanical Strength

Durability is at the heart of the Resi9 range. This miniature circuit breaker is built to last, boasting up to 10,000 electrical cycles and 20,000 mechanical cycles.

Whether you’re performing frequent switching or expecting long-term usage,

R9F32340 is designed to withstand intensive operation while maintaining performance and reliability.

Compact Modular Design for Easy Installation

With a space-saving width of 6 DIN pitches (9mm each), R9F32340 is ideal for modular panel installations.

Its dimensions — 54mm wide, 81mm high, and 72mm deep — make it compact and efficient for standard enclosures.

Installation is quick and simple using a clip-on mount for DIN rail systems, while tunnel-type terminals support a range of conductor sizes for flexibility in wiring.

Safe and Secure Operation in All Conditions

This MCB is rated for an operational voltage (Ue) of 400V AC, insulation voltage (Ui) of 440V, and impulse withstand voltage (Uimp) of 4kV,

so ensuring it functions effectively under various operating conditions. The toggle switch control and clear ON/OFF indication offer user-friendly operation and status visibility.

It supports both rigid and flexible conductors, with a tightening torque of 2 N·m and a wire stripping length of 14mm for secure connections.

Rating of R9F32340 circuit breaker Enhanced Environmental Resistance and Protection

Built to endure harsh environments,

Schneider R9F32340 operates in ambient temperatures ranging from -25°C to +60°C and can be safely stored in conditions as cold as -40°C.

It has an IP20 protection rating (IP40 in an enclosure) in compliance with IEC 60529,

so rating of R9F32340 circuit breaker offering solid resistance to dust and accidental contact.

Its tropicalization level 2 and pollution degree 2 make it suitable for humid and challenging conditions.

Optimized for Distribution Applications

Specially crafted for residential distribution applications, R9F32340 enhances the safety and performance of home electrical systems.

Its thermal-magnetic technology ensures fast, accurate tripping under fault conditions,

so making it an excellent choice for contractors and system integrators seeking reliable circuit protection with minimal maintenance.
