Overcurrent switch, 6kA BKJ63Nd series 2P 2A characteristic B BKJ63Nd 2P B2 BKJ63ND 2P B2

Electrical installation protection with BKJ63Nd circuit breakers

The BKJ63Nd 2P circuit breaker with a rated current of 2A and B characteristic is a reliable element protecting electrical installations in residential and industrial buildings. It provides effective protection against the effects of overloads and short circuits, minimizing the risk of damage to equipment and fires. The two-pole (2P) design allows disconnection of both phase and neutral, which increases safety.

Characteristics and application

BKJ63Nd series circuit breakers with B characteristic are particularly recommended for securing circuits with a mixed character – with resistive and inductive elements. The B characteristic means that the circuit breaker reacts quickly to an increase in short-circuit current, but is more resistant to short-term current surges during the starting of devices with motors or transformers. This reduces the risk of unnecessary tripping of the circuit. The rated current of 2A makes it ideal for protecting lighting or socket circuits with low power consumption.

• Wide range of applications: ideal for installations in residential, commercial and industrial buildings.
• DIN rail mounting: quick and easy mounting on a standard 35mm DIN rail – appreciated by installers.
• High reliability: confirmed by compliance with IEC 60898-1 and IEC 60947-2 standards.
• Durable construction: ensures long-lasting and trouble-free operation (up to 10,000 operating cycles).
• Expandability: compatible with additional accessories, such as terminal strips (SHT) or signaling modules (OVT/UVT).
• Cable capacity: Supports cables with a cross-section of up to 25mm², providing flexibility in the selection of conductors.

Safety and technical parameters

The BKJ63Nd 2P B2 circuit breaker has been designed with maximum safety in mind. It has a short-circuit breaking capacity of up to 6kA at 415VAC, which guarantees effective disconnection of the circuit in the event of a failure. Compact dimensions (17.8mm per pole) allow for efficient use of space in the distribution board. The use of high-quality materials ensures resistance to environmental conditions and long-term stability of operating parameters. These circuit breakers protect against overload and short circuit – they work like standard circuit breakers of this type, providing basic protection for the electrical installation.
