FAQ
Q: What is a 63 amp MCB used for?
A 63 amp miniature circuit breaker protects electrical circuits from overloads and short circuits. Ideal for high-power applications like air conditioners, electric water heaters, or commercial lighting systems in homes, offices, or small industrial setups.
Q: How much load can a 63 amp MCB take?
A 63 amp MCB safely handles continuous loads up to ~50.4A (80% of rated current) to avoid overheating. For short-term surges (e.g., motor startup), it temporarily supports up to 63A.
Q: How to size a miniature circuit breaker?
Calculate the circuit’s maximum load current, add a safety margin (10-20% for motor/inductive loads), and match it to the MCB’s rated current. Ensure the MCB’s rating aligns with wire capacity (e.g., "63 amp mcb wiring diagram" guidelines) and IEC 60898 standards.
Q: What are the three types of miniature circuit breakers?
Commonly categorized by trip characteristics:
- Type B: Sensitive (3-5x rated current), for lighting/small resistive loads.
- Type C: Standard (5-10x), for general appliances (e.g., "63 amp mcb for domestic use").
- Type D: Heavy-duty (10-20x), for motors/inductive equipment.
Q: What’s the delivery time for 63 amp MCB?
Standard models (e.g., "single phase 63 amp mcb") take 1-3 weeks; regional stock may vary. Custom orders require 4-6 weeks.
Q: Does it support OEM?
Yes! We offer OEM services—custom labeling, specifications, or packaging to fit your brand or project needs.
Q: What certifications does it have?
Compliant with global safety standards (covering CE, UL, etc.), ensuring reliability for international use.
Q: How to get 63 amp MCB pricing or contact dealers?
Pricing varies by type (B/C/D) and features. Visit our website or contact customer service for quotes and nearby authorized dealer info.
