Combined switch-disconnector 6kA PFL6-6/1N/C/3 type AC 286464

Combined circuit breaker – reliable protection for electrical installations

This combined circuit breaker, catalog number 286464, combines the functions of an overcurrent and residual current device, providing comprehensive protection for electrical circuits. It is a device designed to protect installations in residential and commercial buildings. Its compact size (2 modules wide) allows for easy mounting in distribution boards.

Functionality and technical parameters

The PFL6-6/1N/C/3 circuit breaker is characterized by a rated current of 6A and a high short-circuit breaking capacity – up to 6kA. Characteristic C provides effective protection against overloads and short circuits, while allowing for trouble-free starting of devices with motors that generate short-term current surges. Additionally, the built-in residual current device with a sensitivity of 30mA (0.03A) protects users from electric shock. The device is designed to operate in AC networks with a voltage of 230V and a frequency of 50Hz.

• Overload protection thanks to characteristic C, providing a delayed response to short-term overloads, which is important for devices with motors.
• Short-circuit protection thanks to a breaking capacity of 6kA guaranteeing quick disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• Protection against electric shock thanks to the built-in AC residual current device with a sensitivity of 30mA effectively detecting leakage currents to earth and disconnecting the power supply, protecting users.
• Universal mounting thanks to the possibility of connecting solid and stranded wires with a cross-section from 1 to 25 mm² facilitating installation in various types of electrical installations.
• High reliability thanks to energy limitation class 3 and protection degree IP20 ensuring durability and resistance to environmental conditions.

Construction and application

The PFL6-6/1N/C/3 circuit breaker has been designed for easy mounting on a DIN rail. It also has a detachable N pole, which facilitates maintenance and service work. Thanks to its compact dimensions (installation depth 69.5mm) it is ideal for use in distribution boards with limited space. It is intended for protecting lighting circuits, socket outlets and other electrical energy consumers in residential and commercial buildings. Additionally, it has dual screw/busbar terminals which increases comfort during installation. Regular testing of the device (every 6 months) confirms its reliability and long-term operation.
