Air Circuit Breaker: • Rated current up to 10,000 A. • Trip characteristics often fully adjustable including configurable trip thresholds and delays.
• Usually electronically controlled—some models are microprocessor controlled. • Often used for main power distribution in large industrial plant, where the breakers are arranged in draw-out enclosures for ease of maintenance. Vacuum Circuit Breaker: • With rated current up to 3000 A, • These breakers interrupt the arc in a vacuum bottle. • These can also be applied at up to 35,000 V.
Vacuum breakers tend to have longer life expectancies between overhaul than do air circuit breakers. RCD ( Residual Current Device ) / RCCB( Residual Current Circuit Breaker): • Phase (line) and Neutral both wires connected through RCD. • It trips the circuit when there is earth fault current. • The amount of current flows through the phase (line) should return through neutral. • It detects by RCD. Any mismatch between two currents flowing through phase and neutral detect by RCD and trip the circuit within 30Miliseconed.
