Overcurrent circuit breaker, 6kA BKJ63Nd series 1P 16A characteristic D BKJ63Nd 1P D16 BKJ63ND 1P D16

Overcurrent circuit breaker BKJ63Nd is a protective element for electrical installations against overloads and short circuits. It belongs to the BKJ63N/Nd series from LS Electric, characterized by reliability and compact size. This model, with a rated current of 16A and D characteristic, is designed to protect circuits with receivers with high starting current, such as motors or transformers.

This single-pole (1P) circuit breaker has a short-circuit breaking capacity of up to 6kA, which ensures effective protection in the event of dangerous overvoltages. Mounting is done on a standard 35mm DIN rail, which facilitates installation and replacement. The device operates at temperatures from -5°C to +40°C, allowing it to be used in a wide range of environmental conditions.

The D characteristic means a delayed response to current increase – the circuit breaker allows for short-term overloads, typical for devices with motors, without unnecessarily disconnecting the circuit. This is important for ensuring the continuity of device operation and avoiding downtime. These circuit breakers comply with IEC 60898-1 and IEC 60947-2 standards, which guarantees their safety and quality. The circuit breaker design allows for connection of conductors with a cross-section of up to 25mm², and its width is only 17.8mm per pole, allowing for optimal use of space in the switchgear.

• Provides protection against overload and short circuit – guaranteeing the safety of the electrical installation and connected devices.
• D characteristic is ideal for circuits with receivers with high starting current (e.g. motors, transformers), allowing to avoid unnecessary shutdowns caused by short-term current surges during device start-up.
• Short-circuit breaking capacity of 6kA effectively interrupts the circuit in the event of a short circuit, minimizing the risk of damage and fire.
• Mounting on a 35mm DIN rail facilitates and speeds up installation and replacement of the circuit breaker.
• Width of 17.8mm per pole allows for efficient use of space in the switchgear.
• Compliance with IEC 60898-1 and IEC 60947-2 standards guarantees safety and high product quality.
• Adapted to operate at temperatures from -5°C to +40°C enables use in various environmental conditions.
