Circuit Breaker Terminologies
Understanding circuit breaker terminology is essential for safe electrical system management and reducing downtime.
Arc Fault Protection (AFP)
Arc Fault Protection (AFP) detects & interrupts arcing faults to reduce fire risks.
Ground Fault Protection (GFP)
Ground Fault Protection (GFP) prevents ground faults and ensures personnel safety.
Overcurrent Protection (OCP)
Overcurrent Protection (OCP) protects against excessive current and prevents device damage.
Short-Circuit Protection (SCP)
SCP- Short-Circuit Protection (SCP) prevents short circuits and minimizes system disturbances.
Trip Curve
Trip Curve is a graphical representation of breaker response time versus fault current to guide selection and settings.
Rated Current (Ir)
Rated Current (Ir) is the maximum current a breaker can handle continuously.
Breaking Capacity (Ib)
Breaking Capacity (Ib) is the highest fault current a breaker may safely interrupt.
