Residual current circuit breaker with overcurrent protection 1P+N 6kA C 16A/10mA Type A ACA966D

Residual Current Circuit Breaker with Overcurrent Protection – Safety and Protection in One

This 1P+N residual current circuit breaker combines overcurrent and residual current protection, providing comprehensive safety for your electrical installation. A rated current of 16A and a tripping current of 10mA make it an ideal solution for protecting circuits with higher power demands, while offering high effectiveness in detecting leakage currents. Characteristic C ensures that the device does not trip unnecessarily during short-term overloads, which is particularly important when operating devices with motors or other elements generating surge currents.

Functionality and Application

The ACA966D residual current circuit breaker is designed to protect people and electrical installations from the effects of short circuits and electric shock. Its 1P+N design means it protects both the phase and neutral conductors, increasing the level of safety. The rated short-circuit breaking capacity of 6kA guarantees effective disconnection of the circuit in the event of a fault. The device finds application in home installations, commercial buildings and industrial facilities where high reliability and protection are required.

Key Features and Benefits

• Multifunctionality: Combination of overcurrent and residual current circuit breaker functions in one device – saves space in the distribution board and simplifies installation.
• Characteristic C: Delayed response to short-term overloads – ideal for circuits with motors, transformers and other loads generating surge currents.
• High Short-Circuit Breaking Capacity: 6kA ensures effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage.
• Sensitivity A: High sensitivity to leakage currents (10mA) – provides a quick response in the event of a risk of electric shock.
• Locking Mechanism: Locking mechanism prevents accidental switching on of the circuit breaker after tripping – additional protection against improper operation.
• Width of 2 Modules: Compact dimensions allow for easy installation even in tight distribution boards.
• Connection Cross-Sections: Possibility to connect solid conductors with a cross-section of 1-25 mm² and stranded conductors 1-16 mm² – flexibility when selecting conductors.
• Operating Temperature: Wide operating temperature range (-25°C to +40°C) – possibility of use in various environmental conditions.
• Compliance with Standards: Meets the requirements of IEC 60898-1 and IEC 61009-1 standards – guarantee of safety and reliability.
