Overcurrent circuit breaker, 6kA series BKN 4P 63A characteristic C BKN 4P C63A

Overcurrent circuit breaker of the BKN series is a reliable protection for electrical installations, designed for both home and commercial use. Model BKN 4P C63A, with a rated current of 63A, effectively protects circuits against overload and short circuit.

Protection and functionality

This four-pole circuit breaker is characterized by a C characteristic, which means it allows for short-term current overloads without unnecessary tripping. This is particularly important when connecting devices with electric motors or other loads generating high starting currents – such as pumps or compressors. This avoids unplanned downtime and ensures continuous power supply. The rated short-circuit breaking capacity of 6kA guarantees effective intervention in the event of a serious failure, minimizing the risk of damage to the installation and equipment.

Installation and application

The BKN 4P C63A circuit breaker is designed for mounting on a DIN rail, which simplifies and speeds up installation. A wide range of wire cross-sections (from 1 to 25 mm²) ensures compatibility with various types of wiring. The IP20 degree of protection protects against finger contact and the ingress of solid objects larger than 12.5 mm, which is standard for devices mounted inside distribution boards. Designed to operate at temperatures from -5°C to 40°C. Equipped with a visual contact position indicator, which facilitates quick identification of the breaker status – whether it is on or off.

Key features

• Short-circuit breaking capacity: 6kA – ensures effective protection of the installation in the event of short circuits.
• Characteristic C: ideal for circuits with loads with high inrush currents.
• Number of poles: 4P – allows protection of multi-phase electrical circuits.
• Wire cross-section: 1…25mm² – a wide range of permissible wire cross-sections provides installation flexibility.
• DIN rail mounting: simplifies and speeds up installation in electrical distribution boards.
• Visual status indicator: allows for a quick assessment of the breaker status without having to open the distribution board.
