Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 10A characteristic D BKJ63Nd 1P D10 BKJ63ND 1P D10

Overcurrent circuit breakers BKJ63Nd – reliable installation protection

The BKJ63Nd overcurrent circuit breaker is a protective element for the electrical installation against overloads and short circuits. This model, with a rated current of 10A and characteristic D, provides effective protection in circuits exposed to high inrush currents, such as those occurring when starting motors or devices with heating elements. The design and parameters of the circuit breaker have been selected to ensure long-term and trouble-free operation.

Construction and application

The BKJ63Nd circuit breaker is designed for mounting on a 35mm DIN rail. Its compact dimensions (17.8mm wide per pole) allow for efficient use of space in the distribution board. The use of characteristic D means that the circuit breaker reacts with a delay to short-term current increases, which minimizes the risk of unnecessary tripping of the circuit during normal operation. This makes it ideal for protecting circuits supplying receivers with high starting currents. This circuit breaker is used both in domestic and industrial installations where high reliability and protection against the effects of overloads are required.

Key features and benefits

• Characteristic D: Provides a delayed response to short-term current increases, protecting against unnecessary tripping of the circuit when starting motors or other devices generating inrush current.
• Breaking capacity 6kA: Guarantees effective circuit interruption in the event of a short circuit, minimizing the risk of damage to the installation and fire.
• DIN rail mounting: Enables quick and easy mounting in the distribution board, saving time and installation costs.
• Width 17.8mm per pole: Compact dimensions allow for efficient use of space in the distribution board.
• Wide operating temperature range (-5°C to +40°C): Ensures reliable operation in various environmental conditions.
• Compliance with IEC 60898-1 and IEC 60947-2 standards: Confirms the safety and high quality of the product.
• Possibility of connecting wires with a cross-section of up to 25mm²: Allows use with various types of installation cables.
• Visual indication of contact status: Allows for a quick assessment of the circuit breaker status without the need for disassembly.

BKJ63Nd circuit breakers are solid and reliable devices that provide comprehensive protection of the electrical installation against the effects of overloads and short circuits – both for professionals performing installations and for end users who value safety and comfort of use.
