2-pole residual current circuit breaker PFIM-40/2/003-G-MW 235451

Residual Current Circuit Breaker (RCCB) PFIM-40/2/003-G-MW is a two-pole device designed to protect electrical installations against the effects of differential and short-circuit currents. It is a key element ensuring safety of use, both in residential and industrial buildings. This model is characterized by high reliability and resistance to interference.

Product features and application

The PFIM-40/2/003-G-MW circuit breaker is designed to work with installations with a rated voltage of 230V and a frequency of 50Hz. Its rated current is 40A, and the rated differential current is 0.03A, providing effective protection against electric shock. The device has a C characteristic, which means it reacts more slowly to short-term current surges, which is particularly important when connecting devices with electric motors or other loads with high starting current. Mounting is on a DIN rail, which simplifies and speeds up installation. Additionally, the circuit breaker has a lock, preventing accidental switching on after switching off due to a failure.

Advantages and benefits

• Versatility: The ability to add auxiliary contacts, undervoltage releases and auto-reclosing devices expands the functionality of the device and allows it to be adapted to the specific needs of the installation.

• Installation flexibility: The power supply direction is arbitrary, which facilitates installation in various conditions.

• Ease of use: Optical contact position indicator allows for quick visual control of the device status.

• Durability and reliability: Short-circuit withstand strength at 10kA and impulse withstand voltage of 3kA guarantee long-lasting and trouble-free operation.

• Safety: Rated impulse withstand voltage of 4kV provides protection against overvoltage.

• Compatibility: The possibility of connecting multi-wire conductors with a cross-section from 1.5 to 16 mm² and single-wire conductors from 1.5 to 35 mm² ensures wide compatibility with various types of conductors.

• Aesthetics and functionality: Screw and busbar terminals from above and below facilitate connection of conductors and provide an aesthetic appearance of the installation.

• Wide operating temperature range: The device retains its properties in the temperature range from -25°C to 60°C, allowing it to be used in various environmental conditions.

The PFIM-40/2/003-G-MW circuit breaker is a solid and reliable solution for anyone who values safety and comfort of use of electrical installation – both for a professional installer looking for a universal product, and for an end user expecting effective protection of their home or company. Its rich range of subtypes allows it to be adapted to the individual needs of each project.
