Schneider R9F32263 | Miniature circuit breaker (MCB), Resi9, 2P, 63A, C curve, 4500A (IEC/EN 60898-1)

Specifications R9F32263

The Schneider R9F32263 is a two-pole miniature circuit breaker designed to ensure reliable protection for residential and light commercial electrical circuits. It is part of the Resi9 series from Schneider Electric, which is known for its safety, efficiency, and compact design.

This MCB has a rated current of 63 amperes, which makes it suitable for circuits with high electrical loads such as large home appliances, air conditioning systems, water heaters, and sub-panels. It operates with a C-curve tripping characteristic, which means it trips within 5 to 10 times the rated current, allowing it to handle moderate inrush currents without unnecessary tripping.

It has a breaking capacity of 4500 amperes under IEC/EN 60898-1 standards. This indicates that the breaker can safely interrupt a fault current up to 4.5kA without damage, making it ideal for environments with low to moderate fault levels. The operational voltage is up to 400V AC, and it is designed for standard 50/60 Hz frequency.

The device is DIN-rail mountable, which makes installation easy and quick inside residential distribution boards. It is built with high-quality, flame-retardant materials for long-lasting durability. The breaker includes a user-friendly toggle switch for manual ON/OFF operation and clear status indication. The operational temperature range supports -5°C to +40°C, ensuring consistent performance in typical domestic conditions.

Features R9F32263

One of the most important features of the Schneider R9F32263 is its dual protection mechanism. It includes both thermal and magnetic tripping functions. The thermal component protects against long-term overloads, while the magnetic element provides instantaneous protection against short circuits.

The C-curve characteristic adds to the safety by providing the right balance between sensitivity and tolerance. It avoids unnecessary tripping during normal startup surges, which are common in appliances like refrigerators and air conditioners.

Its compact and modular design allows more breakers to be fitted in a single distribution board, saving space. The switch is smooth to operate, and the internal components are built for high mechanical endurance, allowing thousands of switching cycles without failure.

The breaker is tested and certified according to international standards, ensuring high quality and performance. It is part of the Resi9 family, which is designed with modern households in mind, offering enhanced protection and easy integration with other Schneider Electric devices.

Applications

The Schneider R9F32263 is ideally suited for residential, commercial, and small industrial applications where reliable circuit protection is required. It is commonly used in:

• Home electrical distribution: for protecting main or sub-circuits supplying high-load appliances such as ovens, washing machines, and air conditioners.

• Lighting and socket circuits: in larger homes or villas, where higher current protection is needed.

• Offices and retail shops: to protect lighting, plug sockets, and small equipment.

• Sub-distribution panels: where a branch circuit needs to be protected before feeding smaller breakers.

• Utility rooms and equipment zones: to protect specific areas or machines within a building.

Because of its two-pole design, it offers complete isolation of both phase and neutral lines, which enhances safety during maintenance and fault clearing.
