Overcurrent circuit breaker, 6kA BKJ63Nd series 2P 32A characteristic C BKJ63Nd 2P C32 BKJ63ND 2P C32

Overcurrent circuit breakers BKJ63Nd – reliable installation protection

The BKJ63Nd overcurrent circuit breaker is a protective device that protects the electrical installation and devices connected to it from the effects of overloads and short circuits. The 2P model with a rated current of 32A and characteristic C provides effective protection in circuits with higher load capacity, such as sockets, lighting or heating devices. The use of characteristic C means that the circuit breaker reacts with a delay to short-term current surges, which is particularly important when connecting devices with electric motors or transformers – this avoids unnecessary tripping of the circuit during the start-up of these devices.

Construction and application

The BKJ63Nd circuit breaker is designed for mounting on a 35mm DIN rail, which facilitates its installation in electrical distribution boards. Thanks to its compact dimensions (17.8mm per pole), it saves space in the distribution cabinet. The possibility of connecting wires using both lugs and screws provides flexibility during installation. These circuit breakers are widely used in residential, commercial and light industrial construction. They are ideal for protecting lighting, socket and electrical circuits for various purposes.

Key features and benefits

• High breaking capacity: 6kA at 415VAC guarantees effective disconnection of the circuit in the event of a short circuit, minimizing the risk of damage to the installation and devices.
• Characteristic C: Provides optimal protection for devices generating high inrush currents during start-up (e.g. motors, transformers).
• Universal wire connection: The possibility of using lugs or screws facilitates and speeds up installation.
• Compact dimensions: Allow for efficient use of space in the distribution board.
• Compliance with standards: The circuit breaker meets the requirements of IEC 60898-1 and IEC 60947-2 standards, confirming its safety and reliability.
• Durable construction: Ensures a long service life of the device – withstands 10,000 electrical operating cycles.
• Wide operating temperature range: Allows use in various environmental conditions (from -5°C to +40°C).
• Two-pole design (2P): Ensures disconnection of both the phase and neutral protective conductor in the event of a failure.

In addition, the BKJ63Nd circuit breakers are characterized by high resistance to mechanical damage and stable operating parameters throughout their service life. A wide range of available rated currents allows you to choose the appropriate model for specific installation needs.
