Residual current circuit breaker 10 kA, In=40 A, IΔN=0.03 A, Type G/F, 4-pole FRCMM FRCMM-40/4/003-G/F 187409

Residual Current Device – Reliable Installation Protection

This four-pole residual current device from Eaton, with a rated current of 40A and a tripping current of 0.03A, is a key element ensuring safety in every electrical installation. Designed to protect against electric shock and damage caused by short circuits, it is perfect for both domestic and industrial applications. Its G/F type construction guarantees high efficiency in various conditions.

Construction and application

The device is designed for mounting on a DIN rail, which facilitates its installation and integration with existing distribution boards. The rated voltage of 240V and high short-circuit breaking capacity (10kA) make it a reliable protection for electrical circuits. The ability to connect wires with a cross-section from 1.5 mm² to 35 mm² (solid core) or from 1.5 mm² to 16 mm² (multi-core) provides flexibility when selecting wires. A mechanical lock increases safety during maintenance and repairs.

Key features and benefits

• High short-circuit breaking capacity (10kA): Provides effective protection against the effects of sudden overvoltages and short circuits, minimizing the risk of damage to equipment and installations.
• Tripping current of 0.03A: Reacts quickly to leakage currents, protecting users from electric shock.
• Type G/F: Universal type of device, suitable for protection against various types of interference.
• DIN rail mounting: Facilitates quick and easy installation in standard distribution boards.
• Width of 4 modules: Compact dimensions allow for efficient use of space in the distribution board.
• Impulse withstand voltage 3kA: Increases the durability and reliability of the device in harsh working conditions.
• Ambient temperature -25°C to +40°C: Possibility of use in a wide range of ambient temperatures.
• Rated impulse withstand voltage Uimp 4kV: Provides resistance to impulse overvoltages from the atmosphere or switching of inductive loads.

This device complies with safety standards and has a protection class of IP20, which means protection against touching with solid objects with a diameter of more than 12.5 mm. Its solid construction and high quality workmanship guarantee long-lasting and trouble-free operation.
