How to Choose Circuit Breakers

Start with the circuit
Load type, cable size, supply system and local rules define the breaker class before brand choice.
Match current and curve
Rated current protects conductors, while B, C and D curves respond differently to inrush current.
Choose pole count
Single-phase, three-phase, neutral switching and panel layout determine 1P, 2P, 3P or 4P selection.
Stay within one system
Busbars, auxiliaries, enclosures and breakers should be compatible within the distribution range.

Safety tip: Circuit breakers are safety devices. Selection and installation should follow local electrical rules and be performed by qualified personnel.

Frequently Asked Questions

What is the difference between B and C curve?
C curve tolerates higher short inrush current than B curve, often used for inductive or motor loads.
Can I replace a breaker with a higher amp rating?
Not without checking cable size, load and regulations. Oversizing can remove conductor protection.
What does pole count mean?
It tells how many conductors the breaker switches or protects.
