Schneider R9F32120 Miniature Circuit Breaker

Reliable Circuit Protection with Schneider R9F32120 circuit breaker

The Schneider R9F32120 Miniature Circuit Breaker (MCB) is part of the trusted Resi9 range,

so engineered for reliable protection in residential electrical installations.

This 1-pole (1P) breaker features a 20A rated current and a C curve tripping characteristic,

so making it ideal for general-purpose residential circuits that may experience moderate inrush currents.

Designed to prevent damage from overloads and short circuits, it delivers dependable performance backed by Schneider Electric’s global reputation for quality.

Efficient and Safe Current Limiting Technology

This MCB incorporates thermal-magnetic trip unit technology, providing a dual-action response: thermal protection against overloads and magnetic protection against short circuits.

The C curve code ensures fast disconnection at 5 to 10 times the rated current (In),

so making it suitable for circuits with moderate starting currents such as lighting systems or socket outlets.

With a breaking capacity of 4500A at 230V AC, it conforms to the EN/IEC 60898-1 safety standards,

so ensuring a high level of operational reliability.

Schneider R9F32120 circuit breaker Ideal for Residential Electrical Distribution

Its limitation class 3 means it significantly reduces the thermal and mechanical stress during a fault, extending the lifespan of your electrical infrastructure and enhancing overall safety.

Schneider R9F32120 circuit breaker Compact and Easy DIN Rail Mounting

It requires only 2 x 9mm pitches (18mm width) of panel space, helping optimize enclosure space without compromising on protection.

Its height (81mm) and depth (72mm) ensure a neat and space-efficient layout inside electrical cabinets.

Durable Performance Under Demanding Conditions

Engineered for longevity, the Schneider R9F32120 offers up to 20,000 mechanical operations and 10,000 electrical operations,

so ensuring extended service life and low maintenance.

It’s built to withstand ambient temperatures from -25°C to 60°C in operation, and -40°C to 60°C in storage,

so making it suitable for a wide range of environments.

With a pollution degree of 2 and overvoltage category III, it is built to perform reliably in demanding residential settings.

User-Friendly Features and Safety Indicators

It also features tunnel-type terminals that accept rigid wires up to 25 mm² and flexible wires with or without ferrules up to 16 mm²,

so ensuring secure and adaptable connections.

A 14mm wire stripping length and 2 N·m tightening torque help simplify installation and maintenance.

Robust Design and International Compliance

Constructed from high-quality, flame-retardant materials, this circuit breaker is compliant with IEC 60898-1 standards and supports IP20 protection,

or IP40 when mounted inside an enclosure, to prevent accidental contact with live parts.

With a rated insulation voltage of 440V AC and impulse withstand voltage of 4kV,

it ensures robust insulation against electrical surges and fluctuations.

Environmentally Adaptable and Packaged for Convenience

With a relative humidity tolerance of up to 95% at 55°C and tropicalisation rating 2 (IEC 60068-1),

R9F32120 is designed to withstand humid and tropical conditions.

It is packaged efficiently for both small and bulk installations, available individually or in bulk packs of 12 or 144 units,

so reducing waste and optimizing supply chain logistics for electrical contractors and retailers alike.
