Overcurrent circuit breaker 6kA PL6-B20/3 286590

6kA Overcurrent Circuit Breaker – Reliable Installation Protection

This three-pole circuit breaker from Eaton's PL6 series is a key element in protecting electrical installations in residential, commercial, and industrial buildings. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage and fires. Its compact dimensions (4 module width) make it easy to install in distribution boards.

Characteristics and application

The PL6-B20/3 circuit breaker is characterized by a B characteristic, which means it is ideal for circuits with devices with moderate inrush current. This characteristic allows it to react quickly to overloads, but at the same time tolerates short-term current surges that occur, for example, when starting electric motors. The rated current of 20A makes it suitable for protecting lighting circuits, socket outlets and other loads with similar power consumption. The rated short-circuit breaking capacity of 6kA (at 400V and 230V) guarantees safe disconnection of the circuit in the event of a serious failure.

• Versatile application: ideal for residential, commercial and industrial construction.
• Overload and short-circuit protection: protects the electrical installation from damage and fire.
• B characteristic: suitable for circuits with devices with moderate inrush current – e.g. lighting, sockets.
• Compact dimensions: easy installation in standard distribution boards (4 modules).
• High reliability: product from a renowned manufacturer – Eaton Electric.

Construction and technical parameters

The circuit breaker is made of high-quality materials, which ensures its durability and reliability. It has a protection degree of IP20, which means protection against contact with fingers and against the ingress of solid objects larger than 12.5 mm. The cross-section of the connected single-wire or multi-wire cable is from 1 to 25 mm², which provides flexibility in the selection of power cables. The width expressed in number of modules is 4, and the installation depth is 70.5 mm. The circuit breaker operates in an ambient temperature range from -25°C to +75°C, which allows its use in various environmental conditions. Compliance with EN 60898 standards and energy limitation class 3 confirm its safety and effectiveness. The rated insulation voltage Ui is 440V and the rated impulse withstand voltage Uimp is 4kV.
