Residual current circuit breaker with overcurrent protection KZS-2M AC B10/0.3 002173302

### Reliable protection for your electrical installation

This KZS-2M AC B10/0.3 residual current circuit breaker with overcurrent protection is a comprehensive solution ensuring safety in your home or business. It protects against electric shock, short circuits and overloads, minimizing the risk of damage and fire. It is a key element of every modern electrical installation, providing peace of mind for both the end user and the installer.

Functionality and technical parameters

The KZS-2M circuit breaker combines the functions of an overcurrent and residual current device, allowing for compact and effective circuit protection. The rated current of 10A and characteristic B make it ideal for protecting lighting circuits, socket outlets and devices with moderate inrush current. The rated residual current of 0.3A ensures a quick response in the event of a ground fault, which is crucial for protecting life and property. The rated short-circuit breaking capacity of 10kA guarantees effective disconnection of the circuit in the event of a short circuit.

• Versatile application: Suitable for TN-S, TN-C-S, TT and IT networks with separated neutral and earth conductors.
• Compact size: 2 module width makes it easy to install in switchboards with limited space.
• Safety of use: Has a test button for regular functional checks and a contact position indicator (ON/OFF) for quick identification of the device status.
• Solid construction: Terminal protection against contact under voltage increases safety during installation and maintenance.
• Installation flexibility: The possibility of mounting auxiliary contacts PS KZS-2M/4M (available separately) expands the functionality of the device.
• Wire connection: Accepts solid and stranded wires with a cross-section from 1 to 25 mm².

Construction and compliance with standards

The circuit breaker has been designed with ease of installation and reliable operation in mind. Its construction allows the use of insulated busbars on both the upper and lower terminals, which facilitates the connection of wires. The "ON/OFF" marking on the actuating lever and the possibility of sealing the lever in the "On" and "Off" positions further increase safety. The device meets the requirements of EN 61009 standard, which confirms its compliance with European safety standards. The degree of protection IP20 provides protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm.
