Frequently Asked Questions (FAQ)
What makes the BKH-b suitable for PLC applications?
The BKH-b is specifically designed with features that complement PLC systems, including precise current ratings, reliable trip characteristics, and compact DIN rail mounting that fits standard control panel configurations. Its 10kA breaking capacity ensures protection against fault currents common in industrial environments.
Can the BKH-b be used with single-phase systems?
While the BKH-b is primarily designed as a 3-pole breaker for three-phase systems, it can be used in single-phase applications by utilizing only one or two poles. However, for optimal performance in single-phase applications, consider single-pole variants from the same product family.
What maintenance is required for the BKH-b circuit breaker?
The BKH-b requires minimal maintenance. Regular visual inspections for physical damage, periodic testing of trip functionality, and ensuring proper torque on connections are recommended. The breaker is designed for long service life with no routine maintenance requirements under normal operating conditions.
How does the BKH-b compare to standard circuit breakers?
The BKH-b offers enhanced features specifically for industrial applications, including higher breaking capacity (10kA vs typical 6kA), wider temperature tolerance, and better vibration resistance. It's designed to withstand the harsh conditions of industrial environments where standard breakers might fail prematurely.
What certifications does the BKH-b hold?
The BKH-b complies with international standards including IEC 60947-2 for circuit-breakers, IEC 60898 for household and similar installations, and various regional certifications. Always verify current certifications with the manufacturer for specific market requirements.
