Residual current device Acti9 iID-100-4-100-A 100A 4-pole 100mA type A A9Z22491

Acti9 iID Residual Current Circuit Breaker — reliable protection against leakage current

This Acti9 iID modular residual current circuit breaker provides comprehensive protection for electrical installations against the effects of leakage current and the risk of fire. The device is designed for maximum reliability and operational safety.

Key design features

The 4-pole design allows for the protection of three-phase circuits with a neutral conductor. The rated current of 100A and type A (100mA) sensitivity ensure optimal protection for most industrial and commercial installations.

The device operates at a rated voltage of 400V AC and a frequency of 50/60 Hz. The design enables mounting on a standard DIN rail, which significantly simplifies installation in modular distribution boards.

Advanced safety functions

VisiTrip technology allows for rapid identification of the faulty circuit, reducing the time required to locate the problem. The VisiSafe function ensures safe working conditions during maintenance and servicing.

The Si (Super Immunis) type guarantees increased immunity to electromagnetic interference, which is particularly important in environments with high levels of network disturbances.

Technical and environmental parameters

The device is characterized by an operating temperature range from -25°C to +60°C, enabling installation in difficult environmental conditions. The IP20 protection rating protects against accidental contact with live parts.

The short-circuit strength is 1.5 kA, and the surge current resistance reaches 0.25 kA. The insulation voltage Ui is 500V, and the impulse withstand voltage Uimp is 6 kV.

Application and practical benefits

The circuit breaker effectively protects against:

• Electric shock (in accordance with IEC 60364)
• Fire risk caused by leakage currents
• Damage to electrical equipment caused by insulation faults

Full coordination with Acti9 iC60 circuit breakers guarantees selectivity of operation and continuity of power to other circuits during a fault in one of them.

Installation and operation

The device width is 4 DIN modules, which facilitates distribution board planning. The installation depth is only 44 mm, allowing for mounting even in shallow enclosures.

The connection conductor cross-sections are in the range of:

• Single-core conductors: 1-35 mm²
• Multi-core conductors: 1-25 mm²

Power loss is only 7W, which minimizes the impact on the installation's energy balance.

Normative compliance

The product meets the requirements of the following standards:

• EN/IEC 61008-1 — for residual current circuit breakers without overcurrent protection
• IEC 60364 — regarding protection against electric shock

The device is adapted for disconnection in accordance with IEC 60947-2, enabling safe service work with the power disconnected.
