2-pole residual current circuit breaker PFIM-25/2/003-G-MW 235449

Residual Current Device – Protection and Safety of Installations

The residual current circuit breaker PFIM-25/2/003-G-MW is a key element of electrical protection, designed to protect people and installations from the effects of short circuits and leakage currents. This device, with a rated current of 25A and a sensitivity of 0.03A, effectively detects abnormalities in the circuit and immediately disconnects it, minimizing the risk of electric shock. Installation is on a DIN rail, ensuring easy installation and integration with existing electrical infrastructure.

Construction and Application

The construction of the circuit breaker is based on a two-pole system, making it an ideal solution for protecting single-phase circuits. The rated voltage of 230V and the insulation voltage Ui of 440V guarantee safe operation under standard operating conditions. This circuit breaker is widely used in residential, commercial and industrial buildings where effective protection against electric shock and damage to installations is required. Thanks to the possibility of adding auxiliary contacts, undervoltage releases and auto-reclosing devices, the device can be adapted to the specific needs of a given facility.

Key Features and Benefits

• Versatile mounting: Screw and DIN rail terminals from above and below facilitate the connection of wires with a cross-section from 1.5 mm² to 35 mm² (solid) and 1.5 mm² to 16 mm² (stranded).
• Configuration flexibility: The ability to expand with additional accessories (auxiliary contacts, undervoltage releases) allows you to tailor functionality to specific application requirements.
• Independence from mains voltage: The operation of the circuit breaker is independent of voltage fluctuations in the network, ensuring reliable protection under all conditions.
• Contact status indicator: Optical contact position indicator facilitates quick diagnostics and identification of any problems with the device.
• Durability and safety: Short-circuit strength of 10 kA and impact current resistance of 3 kA provide effective protection against the effects of overloads and short circuits.
• Compact dimensions: A width of 2 modules allows for efficient use of space in the switchgear cabinet.
• Wide operating temperature range: The device maintains its operating properties in a temperature range from -25°C to +55°C.
• Compliance with standards: It has a CE marking confirming compliance with European safety standards.

Additional information: The circuit breaker is characterized by power losses of 2W at a frequency of 50Hz and a degree of protection of IP20, which means protection against touching with a finger and solid objects larger than 12.5 mm. The color of the housing, close to RAL 7035, provides an aesthetic appearance of the device after installation.
