Overcurrent circuit breaker 6kA PL6-B40/3 286593

Overcurrent circuit breaker – reliable protection for electrical installations

This three-pole overcurrent circuit breaker from Eaton's xPole Home series, with a rated current of 40A and B characteristic, is a key element ensuring safety in every electrical circuit. Designed for both home and commercial building use, it effectively protects the installation against overloads and short circuits. A breaking capacity of 6kA guarantees a quick response in the event of a failure, minimizing the risk of damage and fire.

Functionality and application

The PL6-B40/3 circuit breaker is widely used in protecting lighting circuits, socket outlets and electrical devices with moderate power requirements. The B characteristic makes it ideal for circuits with high inrush current – it allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. Mounting on a TH35 DIN rail simplifies installation and integration with existing electrical infrastructure.

• Overload protection: Protects the circuit against overload and short circuit – like most circuit breakers in this class.
• Fast response: Breaking capacity of 6kA ensures a rapid response in the event of a failure.
• Versatility: Suitable for protecting various types of circuits – lighting, socket and electrical devices.
• Easy installation: Mounting on a TH35 DIN rail simplifies installation and replacement.
• Safety: Compliance with IEC/EN 60898-1 confirms a high level of safety and reliability.
• Wide operating temperature range: Allows operation in harsh environmental conditions (-25°C to +75°C).

Technical parameters and construction

The circuit breaker is characterized by a solid construction and high quality workmanship. It has a protection class of IP20, which provides protection against accidental contact and against the ingress of solid objects larger than 12.5 mm. Made of high-quality materials resistant to mechanical and thermal damage, which translates into a long service life of the device. The cross-section of the connected solid or stranded wire is from 1 to 25 mm², which provides great flexibility when choosing power cables. The width of the circuit breaker is 3 modules (52.5 mm), which allows for efficient use of space in the distribution board. The rated voltage is 400V and the rated impulse withstand voltage is 4kV. Power losses are 11.2W at rated voltage.
