Residual current circuit breaker FH204 AC-25/0.03 - 4-pole 2CSF204002R1250

Safety and Reliability in Your Electrical Installation

The FH204 AC-25/0.03 Residual Current Device (RCD) is a key element ensuring the protection of people and equipment in electrical installations. Its four-pole design makes it ideal for securing circuits requiring comprehensive protection against the effects of short circuits and leakage currents. This model, with a rated current of 25A and a sensitivity of 0.03A, effectively responds to dangerous situations, minimizing the risk of electric shock and equipment damage.

Characteristics and Application

The FH204 AC-25/0.03 RCD is designed to protect circuits with a rated voltage of 400V and a frequency of 50Hz. Its main task is to detect earth leakage currents and quickly disconnect the power supply if the permissible threshold is exceeded. This ensures a high level of safety when using the electrical installation in both residential and commercial buildings. The use of AC characteristics means that the RCD reacts to alternating currents with a sinusoidal waveform – typical of most electrical appliances.

• Protection against electric shock: Quick detection and disconnection of power in the event of leakage currents minimizes the risk to users.
• Equipment protection: Protects connected devices from damage caused by short circuits or overloads.
• DIN rail mounting: Enables easy and quick installation in a distribution board.
• Locking: Provides additional safety, preventing accidental disconnection of the RCD.
• Short-circuit strength: Withstands short-circuit currents up to 1kA, guaranteeing reliable operation in difficult conditions.

The FH204 AC-25/0.03 RCD is characterized by a solid construction and high quality workmanship. A width of 4 modules allows for efficient use of space in the distribution board. The cross-section of the connected multi-wire cable from 10 to 25 mm² ensures compatibility with various types of cables. The rated impulse withstand voltage of 4kV guarantees resistance to overvoltages. The ambient temperature in operating conditions from -5°C to 40°C allows the RCD to be used in various environments. The IP2X degree of protection provides protection against touching with a finger and against the ingress of solid objects with a diameter of more than 12.5 mm. The RCD meets the relevant safety standards, confirming its reliability and effectiveness.
