Residual current circuit breaker iID-63-4-300-AC 63A 4-pole 300mA type AC A9Z14463

Residual Current Circuit Breakers – Safety and Reliability in Your Installation

This four-pole residual current circuit breaker iID-63-4-300-AC with a rated current of 63A and a sensitivity of 300mA is a key element ensuring the protection of people and equipment in electrical installations. The device is designed to protect circuits against the effects of leakage currents, minimizing the risk of electric shock and preventing damage to equipment. DIN rail mounting simplifies integration with existing electrical infrastructure.

Characteristics and Application

The iID-63-4-300-AC circuit breaker is designed to operate in alternating current (AC) networks with a rated voltage of 400V and an insulation voltage of 500V. Its construction based on Acti9 technology guarantees high reliability and long life. The rated differential current of 0.3A provides effective protection against dangerous leakage currents, and the high short-circuit strength (10kA) allows for safe operation in the event of a short circuit. The device finds application in both domestic and industrial installations where high effectiveness of shock protection is required.

Key Features and Benefits

• High breaking capacity: Short-circuit strength at the level of 10kA ensures effective disconnection of the circuit in the event of a short circuit, protecting devices and the electrical installation from damage.
• Wide operating temperature range: The ability to operate in a temperature range from -5°C to 60°C means that the circuit breaker can be used in various environmental conditions.
• DIN rail mounting: Standard DIN rail mounting simplifies installation and replacement of the circuit breaker, saving time and costs associated with installation work.
• Locking device: Provides additional safety, preventing accidental operation or disconnection of the circuit breaker.
• Wire cross-sections: Accepts solid wires with a cross-section of 1…35 mm² and stranded wires 1…25 mm², ensuring compatibility with various types of cabling.
• Compliance with standards: Meets the requirements of EN/IEC 61008-1 standards, guaranteeing safety and compliance with applicable regulations.
• Contact position indicator: Allows for quick visual assessment of the circuit breaker status – whether it is on or off.
• Pollution degree 3: Resistant to dust and moisture, which increases its durability in harsh operating conditions.
• Power losses: Low power losses (3.5W) translate into energy savings during device operation.
