Molded-shell circuit breaker is a type of electrical protection device commonly used when the load current exceeds the capacity of miniature circuit breaker. They are also used in applications of any current rating requiring adjustable trip settings, which are not available in plug-in circuit breakers and MCBs. Molded case circuit breaker, MCCB for short, is […]

Air circuit breakers have open main contacts and are not sealed in a vacuum, oil or gas (SF6) bottle. They are primarily used in medium to low voltage applications and are capable of high amperage ratings. These types of switchgears have a charging spring that’s used to close the breaker and trip the breaker. Normally […]

Active Harmonic Filter overview Active Harmonic Filter (AHF) is a perfect all-round solution for grid power quality problems such as harmonics (can thoroughly filter out 2nd to 50th harmonic interference), reactive power, loss 3 phase load balancer. Active harmonic filters are connected in parallel in the grid, to detect harmonics in the grid in real […]

Harmonics caused by inverters can cause many problems in your facility, including circuit breakers, capacitor bank failures, motor failures, blown fuses, and damaged cable insulation. BTB products can reduce these harmonics to improve power quality and protect the motor. The “AHF” filter is an elite harmonic filter applied in the system that reduces harmonics to […]

The increasing use of modern power electronics (drives, uninterruptible power supplies, etc.) generates nonlinear currents and thus loads the network with harmonics. The capacitance of the capacitor forms a resonant circuit in conjunction with the power supply transformer. Experience shows that the self-resonant frequency of this circuit is usually in the range of 250 - […]
