Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 2A characteristic D BKJ63Nd 1P D2 BKJ63ND 1P D2

Overcurrent circuit breaker BKJ63Nd – reliable installation protection

This single-pole circuit breaker from the BKJ63Nd series, with a rated current of 2A and D characteristic, is a key element in protecting electrical installations. Designed to protect against overloads and short circuits, it ensures safety in both domestic and industrial applications. This circuit breaker is designed for mounting on a DIN rail and is characterized by high reliability and long service life.

Functionality and application

BKJ63Nd circuit breakers are a universal solution for a wide range of applications. The D characteristic makes them particularly recommended for circuits powering devices generating inrush currents during start-up – such as motors, transformers or switch-mode power supplies. This ensures that the circuit breaker does not trip unnecessarily during short-term current surges, ensuring uninterrupted power supply. Use in industry, construction and in residential installations guarantees effective protection against the effects of failures.

Key features and benefits

• D characteristic: Provides delayed operation in the event of short-term overloads, ideal for devices with high starting current. Helps avoid unnecessary shutdowns caused by momentary load increases.
• Breaking capacity 6kA: Guarantees safe disconnection of the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• DIN rail mounting: Enables quick and easy mounting in electrical switchboards, saving time and installation costs.
• Wide voltage range: Suitable for operation in 230/400V AC networks, which increases its versatility.
• Durable construction: Made of high-quality materials ensuring long life and reliable operation even in difficult operating conditions.
• Protection class IP20: Provides protection against accidental contact and against the ingress of solid objects larger than 12mm.
• Wide operating temperature range: From -5°C to +40°C allows the circuit breaker to be used in various environments.
• Compliance with IEC 60898-1 and IEC 60947-2 standards: Confirms the safety and quality of the product, giving confidence in compliance with applicable regulations.

In addition, the compact dimensions (17.8mm per pole) allow for efficient use of space in the switchboard. The circuit breaker is compatible with wires up to 25mm² in cross-section, providing flexibility when selecting the appropriate wire for a given application.
