4-pole residual current circuit breaker PFIM-63/4/003-A-MW 235443

Residual Current Device – Safety and Installation Protection

This four-pole residual current device from Eaton is a key element ensuring safety in every electrical installation. It provides protection against electric shock, effectively disconnecting the circuit in the event of a ground fault current. This is particularly important in wet rooms such as bathrooms or kitchens, as well as in outdoor installations. Made of high-quality materials, it guarantees reliable operation and long service life.

Characteristics and application

The PFIM-63/4/003-A-MW circuit breaker is designed to protect circuits with a rated current of 63A. Its residual current sensitivity is 0.03A (30mA), ensuring a quick response in the event of a hazard. The design with a lock prevents accidental switching on of the circuit breaker after it has been switched off by a differential trip – an additional safety feature for installers and users. Mounting is done on a standard DIN rail, which facilitates integration with existing distribution boards. A width of 4 modules allows for efficient use of space in the distribution cabinet.

Advantages and benefits

• High reliability: Short-circuit strength at 10kA guarantees resistance to overloads and short circuits, protecting both the device and the entire electrical installation.
• Wide range of applications: The ability to connect wires with a cross-section from 1.5 mm² to 16 mm² (multi-stranded) and from 1.5 mm² to 35 mm² (solid) ensures compatibility with various types of wires used in electrical installations.
• Safety of use: A lock preventing accidental re-engagement of the circuit breaker after it has tripped increases the safety level for users of the installation.
• Easy installation: Standard DIN rail mounting allows for quick and trouble-free integration with an existing electrical distribution board – saving time during installation for professionals.
• Versatility: Suitable for use in both domestic and industrial installations where high protection against electric shock is required.
• Resistance to external conditions: Operation at temperatures from -25°C to 60°C and a protection degree of IP20 ensure reliable operation even in difficult environmental conditions.
• Additional equipment: The ability to expand with additional accessories allows you to adapt the circuit breaker to the specific needs of a given installation.

Thanks to this residual current device, you can be sure that the electrical installation is safe and protected against the effects of failures and dangerous leakage currents.
