Residual current circuit breaker iID-80-4-30-AC 80A 4-pole 30mA type AC A9Z11480

Residual Current Device (RCD) iID-80-4-30-AC is a reliable protection for electrical installations, designed for both domestic and commercial/industrial applications. The device, with a rated current of 80A and a sensitivity of 30mA type AC, effectively protects people from electric shock and the installation from the effects of short circuits to earth. The four-pole design provides comprehensive circuit protection.

Functionality and Application

This switch, mounted on a DIN rail, is characterized by high selectivity and a fast response to dangerous leakage currents. Its versatility makes it suitable for protecting lighting circuits, socket outlets, and electrical appliances. Thanks to its compact size (4 modules wide), it can be easily integrated into an existing distribution board. The use of AC characteristics makes it particularly effective in detecting leakage currents with a frequency of 50/60 Hz – typical for most electrical installations.

Construction and Parameters

The switch is designed for durability and reliability. It withstands surge currents up to 0.25 kA and short-circuit currents up to 10 kA. Its housing provides an IP20 degree of protection, protecting against accidental contact. Conductors with a cross-section from 1 mm² to 35 mm² (solid) or from 1 mm² to 25 mm² (stranded) can be connected directly to the switch terminals. A wide operating temperature range (-5°C to +60°C) guarantees correct operation in various environmental conditions. The rated insulation voltage Ui is 500V and the rated impulse withstand voltage Uimp is 6kV, providing additional safety. The power loss of the device is 5.6W at a frequency of 50/60Hz.

This RCD stands out with its high rated current of 80A, allowing it to protect circuits with high power consumption. A sensitivity of 30 mA ensures a quick response to leakage currents and minimizes the risk of electric shock. The four-pole design guarantees comprehensive protection of the entire circuit, and DIN rail mounting facilitates quick and safe installation in the distribution board. Short-circuit withstand capacity at 10 kA indicates high resistance to overloads and short circuits. The compact width of 4 modules saves space in the distribution board, and the ability to connect conductors with a cross-section of up to 35mm² provides flexibility in conductor selection.
