PFIM-40/4/03-A-MW Residual Current Circuit Breaker 4-pole 235441

Residual Current Device (RCD) is a key element of any electrical installation, ensuring the safety of users and equipment. Model PFIM-40/4/03-A-MW, with a rated current of 40A and a tripping current of 0.3A type A, effectively protects against electric shock and damage resulting from leakage current to earth. It is a four-pole device, meaning it protects the entire circuit.

Mounting is on a DIN rail, which simplifies and speeds up installation. This RCD is designed to operate in AC networks with a voltage of 400V, and its rated insulation voltage is 440V. The rated impulse withstand voltage Uimp is 4kV. The width of the device, 4 modules, allows for efficient use of space in the distribution board.

This RCD is distinguished by its high short-circuit strength of 10kA and impact current resistance of 0.25kA. This makes it reliable even in difficult working conditions. Additionally, it has a mechanical lock that prevents accidental switching on or off during maintenance or service work. The possibility of additional equipment allows the RCD to be adapted to specific installation needs.

• Versatile application: ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• Safety: provides effective protection against electric shock and damage to the installation.
• Easy installation: thanks to DIN rail mounting, installation is quick and simple.
• High quality: made of durable materials, resistant to mechanical damage and weather conditions (ambient temperature in operating conditions: -25 ... 60 °C).
• Wide range of conductors: allows connection of solid conductors with a cross-section of 1.5 ... 35 mm² and stranded conductors with a cross-section of 1.5 ... 16 mm².
• Compliance with standards: meets the required safety and quality standards (degree of protection IP20).

The PFIM-40/4/03-A-MW RCD is characterized by low power losses of 8.8W at a frequency of 50Hz and a pollution degree of 2, which ensures its reliable operation in various industrial and domestic environments. The housing of the RCD is close to RAL 7035 – typical for electrical installation devices – which provides an aesthetic appearance of the installation. The device does not have short-circuit tripping or selective protection function.
