## Summary description

The LSiS BKN 2P B63A is a high-quality 2-pole miniature circuit breaker designed for reliable electrical circuit protection. With a rated current of 63A and a breaking capacity of 6kA, it features a B-type tripping characteristic. This device is ideal for residential and commercial electrical installations, providing effective protection against overloads and short circuits to ensure system safety and operational stability.

## Long description

The LSiS BKN 2P B63A is a professional-grade 2-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits in various environments. This device is designed to monitor current flow and automatically disconnect the circuit in the event of an overload or short circuit, thereby preventing damage to wiring and connected equipment. With a robust construction and precise tripping mechanism, it ensures consistent performance and long-term operational safety for residential and commercial electrical systems.
Advantages
This miniature circuit breaker offers high reliability through its specialized B-curve tripping characteristic, which is optimized for circuits with low surge currents. The 2-pole design allows for the simultaneous disconnection of both phase and neutral lines, enhancing safety during maintenance or fault conditions. Its compact form factor facilitates easy installation in standard distribution boards, while the 6kA breaking capacity provides sufficient protection for typical domestic and light commercial electrical loads.
Suitable for
Residential electrical distribution boards
Commercial lighting and power circuits
Protection of resistive loads
General purpose electrical installations
When it may not be suitable
This circuit breaker is not intended for use in circuits with high inrush currents, such as those powering large motors or transformers, where a C or D curve breaker would be more appropriate to prevent nuisance tripping. It is also not suitable for industrial applications requiring higher breaking capacities or specialized environmental protection.
Key specifications
Number of poles: 2
Rated current: 63A
Breaking capacity: 6kA
Tripping characteristic: B-curve
Mounting type: DIN rail
How to use
The device should be installed by a qualified electrician in accordance with local electrical regulations. It is designed to be mounted onto a standard 35mm DIN rail within an enclosure. Ensure that the supply cables are securely connected to the input terminals and the load cables to the output terminals, observing the correct torque settings to prevent loose connections. Once installed, the toggle switch can be used to manually energize or de-energize the circuit.
What to consider before purchase
Verify that the 63A rating matches your circuit requirements
Ensure the B-curve characteristic is compatible with your connected appliances
Check available space in your distribution board
Confirm that the 6kA breaking capacity meets local safety standards
Usage recommendations
Regularly inspect the circuit breaker for signs of thermal damage or loose connections. Test the manual switching mechanism periodically to ensure smooth operation. If the breaker trips, investigate the cause of the overload or short circuit before resetting the device.
