Overcurrent circuit breaker, 6kA BKJ63Nd series 4P 3A characteristic C BKJ63Nd 4P C3 BKJ63ND 4P C3

Electrical installation protection with BKJ63Nd circuit breakers

The BKJ63Nd circuit breaker is a reliable safety element for electrical installations, protecting against the effects of overloads and short circuits. Designed for use in both residential and industrial buildings, it provides effective protection for wires and connected devices. This four-pole (4P) circuit breaker with a rated current of 3A and C characteristic is an ideal solution for circuits requiring protection against surge currents, such as those occurring when starting motors or devices with heating elements.

Characteristics and application

BKJ63Nd series circuit breakers are characterized by high resistance to mechanical and electrical damage, guaranteeing long-term and trouble-free operation. The C characteristic means that the circuit breaker reacts to overload currents in the range of 5 to 10 times the rated current, which helps avoid unnecessary shutdowns caused by short-term load increases. This makes it particularly recommended for protecting circuits powering devices generating high inrush currents.

• Versatile application: ideal for installation in residential, commercial and industrial buildings.
• Overload and short circuit protection: ensures the safety of the electrical installation and connected devices.
• C characteristic: minimizes the risk of false tripping when starting high-power devices.
• DIN rail mounting: enables quick and easy mounting in electrical switchboards.
• High durability: ensures long-lasting and reliable operation in various environmental conditions.

Technical parameters and construction

The BKJ63Nd circuit breaker has been designed with ease of installation and use in mind. It has screw terminals or lugs (depending on the version), which facilitates the connection of wires. The housing made of high-quality plastic provides electrical insulation and resistance to mechanical damage. The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and reliability. It is designed to operate at temperatures from -5°C to +40°C, making it a universal solution for various installation conditions. The rated short-circuit breaking capacity is 6kA, which guarantees effective protection in the event of a short circuit in the installation.
