Residual current circuit breaker type G/B 4-pole FRCdM-40/4/03-G/B 167897

Residual Current Device – Protection and Safety of the Installation

This four-pole residual current device type G/B is a key element ensuring safety in every electrical installation. Designed to protect against electric shock and fire, it effectively reacts to leakage currents, cutting off the power supply in the event of a detected hazard. Model FRCdM-40/4/003-G/B is characterized by high reliability and durability, making it an ideal choice for both professional installers and demanding end-users.

Construction features and application

The device is designed for mounting on a DIN rail, which facilitates its installation and integration with existing electrical infrastructure. Its compact dimensions (width of 4 modules) allow for efficient use of space in the distribution board. The cross-section of the connected solid wire up to 35 mm² and stranded wire up to 16 mm² ensures compatibility with various types of cables. The rated differential current at 0.3 A guarantees effective protection against dangerous leakage currents. The device finds application in circuits with a rated voltage of 415 V and a frequency of 50 Hz, protecting against the effects of short circuits, overloads and faulty insulation.

Advantages and benefits

• High breaking capacity: Short-circuit strength at 10 kA ensures reliable operation in the event of serious failures.
• Wide operating temperature range: The ability to operate in a temperature range from -25°C to 50°C makes the device suitable for use in various environmental conditions.
• Locking mechanism: Integrated locking mechanism prevents accidental switching on of the device after it has been switched off by a differential current – additional protection for installers and users.
• Selective protection: Selective protection function allows for precise disconnection of the damaged circuit without affecting the remaining parts of the installation.
• Status indicator: Allows for quick visual assessment of the device status and any problems with its operation.
• Compliance with standards: Meets safety requirements, ensuring compliance with applicable regulations (has CE marking).
• Expandability: Compatibility with additional equipment allows you to adapt the device's functionality to the specific needs of the installation.
• Impulse withstand: Withstands impulse currents of 3 kA, which increases its durability and reliability in difficult operating conditions.
• Solid construction: Made of high-quality materials (housing in RAL 7035 color), guarantees long-lasting and trouble-free operation.
