Residual current circuit breaker with overcurrent protection 3x1P+N 6kA C 16A/30mA Type A QC/QBB ADZ366D

Safety and reliability in your electrical installation

This residual current circuit breaker with overcurrent protection is a key element ensuring the protection of people and equipment in electrical installations. The ADZ366D model combines the functions of an overcurrent and residual current circuit breaker, offering comprehensive protection against the effects of overloads, short circuits and electric shock. This device is designed for use in 230V circuits, both in residential and commercial buildings.

Functionality and application

This circuit breaker is ideal for protecting circuits with a rated current of 16A. Characteristic C ensures that the device reacts quickly to short circuits, but is more resistant to short-term current surges that can occur during the starting of motors or other devices with high power consumption. The rated differential current of 30mA guarantees a quick response in the event of a current leakage to earth, minimizing the risk of electric shock. The 3x1P+N design means it protects three phases and the neutral conductor.

Construction and installation

The device, with a width of 4 modules, is mounted on a DIN rail, which facilitates its installation and replacement. The use of the QuickConnect (QC) system further speeds up the connection of wires. The solid construction with a mechanical lock ensures safe operation and prevents accidental disconnection. The possibility of flush mounting increases installation flexibility. The IP2X degree of protection protects against touching live parts and the ingress of solid objects larger than 12.5 mm.

Key features for professionals:

• Rated short-circuit breaking capacity (Icn): 6kA – ensures effective disconnection of the circuit in the event of a short circuit.
• Characteristic C: Optimal for circuits with inductive loads (e.g. motors).
• QuickConnect system: Enables quick and easy connection of wires.
• Mechanical lock: Ensures safety and prevents accidental disconnection of the circuit breaker.
• Rated impulse withstand voltage (Uimp): 4kV – resistance to impulse overvoltages.

Benefits for the end user:

• Comprehensive protection: Protects against overloads, short circuits and electric shock.
• High reliability: Guarantees long-term and safe operation of the electrical installation.
• Family safety: Minimizes the risk of accidents caused by electrical failures.
• Easy installation (for installers): Quick installation thanks to the QuickConnect system and DIN rail mounting.
• Meets safety standards: Compliant with applicable EN 61009-1 standards, ensuring the highest level of safety.
