Residual current circuit breaker type S/Bfq 4-pole FRCdM-25/4/03-S/Bfq 167908

Safety and Reliability in Your Electrical Installation

This four-pole residual current circuit breaker Eaton FRCdM-25/4/03-S/Bfq is a key element ensuring the protection of people and equipment against electric shock and the effects of short circuits. A rated differential current of 0.3A guarantees a quick response in the event of a ground fault, minimizing the risk of hazard. This circuit breaker is designed to operate in installations with a voltage of 415V and a frequency of 50Hz.

Design and Application

The circuit breaker is designed for mounting on a DIN rail, which facilitates its installation and replacement. A width of 4 modules allows for efficient use of space in the distribution board. The S/Bfq application makes it particularly recommended for use with frequency inverters, ensuring their proper operation and protection. The short-circuit strength of 10kA provides resistance to sudden current surges, and the locking mechanism prevents accidental switching on of the circuit breaker after tripping. The cross-section of the connectable solid wire up to 35mm² and stranded wire up to 16mm² provides great flexibility when selecting cables.

Key Features and Benefits

• High selectivity: Selective protection allows for precise disconnection of the damaged circuit without interrupting the power supply to the remaining parts of the installation.

• Resistance to external conditions: A wide operating temperature range from -25°C to 60°C enables the use of the circuit breaker in various environmental conditions.

• Safety of use: Rated impulse voltage withstand of 4kV provides additional protection against overvoltages.

• Durable construction: Made of high-quality materials guarantees long-lasting and reliable operation of the device (housing in RAL 7035 color).

• Versatility: Additional accessories allow you to adapt the circuit breaker to specific installation requirements.

• Protection against overload and short circuit: The circuit breaker effectively protects the circuit against overload and short circuit — as with most circuit breakers in this class.

• Compliance with standards: Meets the required safety standards, which confirms its high quality and reliability.
