Residual Current Device (RCD) iID-40-4-100-AC 40A 4-pole 100mA type AC A9Z12440

Safety and reliability in your electrical installation

This four-pole residual current circuit breaker iID-40-4-100-AC is a key element ensuring the protection of people and devices in electrical installations. Designed by Schneider Electric, model A9Z12440 combines compact size with high performance, making it an ideal choice for both professional installers and end users. The device is designed to protect circuits with a rated current of 40A, reacting to leakage currents of 100mA of type AC.

Functionality and installation

The circuit breaker is mounted on a DIN rail, which facilitates and speeds up its installation. Its width, measuring 4 modules (72mm), allows for efficient use of space in the distribution board. Solid construction and high quality workmanship guarantee long-lasting and trouble-free operation. The mechanical lock prevents accidental disconnection of the device, increasing safety.

Technical specifications and application

The device is characterized by high technical parameters, such as rated voltage 415V, insulation voltage 500V and impulse withstand voltage up to 0.25kA. Short-circuit strength at the level of 10kA ensures its reliable operation even in difficult operating conditions. Adapted to work at temperatures from -5°C to 60°C, it will work in a wide range of applications – from residential installations, through commercial ones, to industrial ones. AC type application means protection against sinusoidal leakage currents, which are the most common threat in electrical installations. The cross-sections of conductors connected to the circuit breaker are 1…35 mm² for solid conductors and 1…25 mm² for stranded conductors – which provides great flexibility in choosing conductors.

• Protection against electric shock: Provides effective protection against electric shock by quickly detecting and disconnecting the circuit in the event of a leakage current.
• Wide range of applications: Ideal for protecting lighting circuits, socket outlets and electrical appliances in residential and commercial buildings.
• Easy installation: DIN rail mounting allows for quick and easy installation without the need for specialized tools.
• High reliability: Made of high-quality materials guarantees long-lasting and trouble-free operation of the device.
• Compliance with standards: Meets the requirements of EN/IEC 61008-1 standard, which confirms its safety and compliance with applicable regulations.
• Mechanical lock: Additional protection against accidental disconnection of the circuit breaker.
