Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 3A characteristic D BKJ63Nd 1P D3 BKJ63ND 1P D3

Overcurrent circuit breaker BKJ63Nd 1P D3 is a safety element protecting the electrical installation against overloads and short circuits. It belongs to the BKJ63Nd series from LS Electric, characterized by high reliability and durability. It is designed to work with circuits with a voltage of 240/415V AC, and its rated current is 3A.

This single-pole (1P) circuit breaker with D characteristic provides a delayed response in the event of short-term current surges, which is particularly important when protecting circuits with receivers with high starting current – such as electric motors or heating devices. The D characteristic means that the circuit breaker will not trip immediately during short-term overloads, which helps to avoid unnecessary shutdowns.

The BKJ63Nd circuit breaker has a short-circuit breaking capacity of 6kA, which guarantees effective protection of the installation in the event of serious disturbances. Mounting is done on a standard 35mm DIN rail, and its compact dimensions (68x81x18 mm) facilitate installation even in tight switchboards. Made of high-quality materials, it ensures a long mechanical life (20,000 cycles) and electrical life (10,000 cycles).

• Protection against overload and short circuit: Protects the electrical installation and devices connected to it.

• D characteristic: Delayed response to short-term current surges – ideal for devices with motors or heaters.

• 6kA breaking capacity: Effective protection in the event of serious failures.

• Mounting on 35mm DIN rail: Quick and easy installation in standard switchboards.

• Durable construction: Ensures long life and reliable operation.

• Wide operating temperature range: From -5°C to +40°C allows use in various environmental conditions.

The BKJ63Nd circuit breakers meet the requirements of IEC 60898-1 and IEC 60947-2 standards, which confirms their safety and compliance with applicable regulations. These are components intended for both professional installers and end customers looking for reliable protection for their electrical installations. Thanks to their design and technical parameters, they are an optimal solution for various applications in residential, commercial and industrial construction.
