MCBs (Miniature Circuit Breakers) kayi prakar ki hoti hain, har ek apne specific upayog aur protection level ke liye design hoti hai. Kuch mukhya types hain:
1. **Single-Pole MCB (SP-MCB)**: Ek single-pole MCB ek current-carrying conductor ko protect karta hai. Yeh aam taur par residential aur light commercial applications ke liye hota hai.
2. **Double-Pole MCB (DP-MCB)**: DP-MCB do current-carrying conductors ko protect karta hai. Iska istemal higher voltage circuits, jaise ki 240V, ke liye hota hai.
3. **Three-Pole MCB (TP-MCB)**: TP-MCB teen current-carrying conductors ko protect karta hai. Ise tino phase ke circuits mein istemal kiya jata hai, jaise ki industrial power systems mein.
4. **Four-Pole MCB (FP-MCB)**: FP-MCB chaar conductors ko protect karta hai. Isme teen phase aur ek neutral hota hai. Ise three-phase, four-wire systems ke liye istemal kiya jata hai.
5. **Aur bhi Specialized MCBs**: Kuch aur MCBs specific requirements ke liye banti hain jaise ki RCCB (Residual Current Circuit Breaker) jo insulation faults ko detect karta hai aur GFCI (Ground Fault Circuit Interrupter) jo ground faults ko rokta hai.
Har MCB ek specific current rating aur short-circuit breaking capacity ke sath aata hai. Aapke application ke anusaar, aapko uchit MCB ka chayan karna chahiye.
