2-pole residual current circuit breaker PFIM-25/2/003-A-MW 235424

Residual Current Device – Protection and Safety of Installations

This two-pole residual current device from Eaton, model PFIM-25/2/003-A-MW, is a key element ensuring safety in electrical installations. Its function is to quickly detect and disconnect circuits in the event of leakage currents, minimizing the risk of electric shock and equipment damage. Equipped with characteristic A, it is particularly effective in protecting against leakage currents with frequencies close to 50 Hz, typical of household and commercial appliances.

Construction and Application

The device is designed for mounting on a DIN rail, which facilitates its installation and integration with existing electrical infrastructure. A width of 2 modules allows for efficient use of space in the distribution board. Suitable for operation in temperatures from -25°C to 55°C, it will perform well in various environmental conditions. The rated differential current of 0.03 A provides high sensitivity in detecting leakage. The locking mechanism of the device prevents accidental switching on after switching off due to differential current – important from a safety point of view during maintenance or repairs.

Key Features and Benefits

• High protection efficiency: Rated differential current of 0.03 A and type A sensitivity guarantee a quick reaction to dangerous leakage currents, protecting people and equipment.
• Solid construction: Short-circuit strength at the level of 10 kA ensures resistance to the effects of short circuits in the installation.
• Easy installation: DIN rail mounting significantly speeds up installation and facilitates the replacement of existing devices.
• Wide range of applications: Suitable for securing circuits with conductor cross-sections from 1.5 mm² to 35 mm² (solid) and from 1.5 mm² to 16 mm² (stranded).
• Safety of use: The locking mechanism prevents accidental re-engagement of the device after intervention, increasing safety during service work.
• Expandability: Compatibility with additional elements (e.g. auxiliary switch Z-HK 248432) allows you to adapt the functionality of the device to the specific needs of the installation.
• Compliance with standards: Meets the requirements of IEC/EN 61008 standards, which confirms its quality and safety of use.

The PFIM-25/2/003-A-MW circuit breaker is a reliable solution for anyone who cares about electrical safety in their home or company – both for professional installers and end users looking for effective protection against electric shock and damage to electrical equipment.
