FAQ
1.What is a double pole MCB?
A double pole MCB (2-pole MCB) is a circuit protection device with two independent current-carrying poles, designed to simultaneously disconnect both the live (L) and neutral (N) conductors in single-phase AC circuits. It provides overload and short-circuit protection, ensuring complete isolation of the circuit during tripping or maintenance.
2.What is the difference between 1-pole and 2-pole MCB?
- 1-pole MCB: Disconnects only the live (L) conductor, suitable for low-current devices (e.g., lighting, small appliances) with plugs, offering basic overload/short-circuit protection at lower cost.
- 2-pole MCB: Disconnects both live (L) and neutral (N) conductors, providing full isolation for safety-critical applications (e.g., main power inputs, large appliances like ACs, water heaters). Ideal for scenarios requiring insulation testing or repair work.
3.Why use a 2-pole MCB?
2-pole MCBs are used to ensure complete electrical isolation of both live and neutral lines, critical for:
- Main power distribution panels (facilitating safe leakage/insulation testing).
- Large appliances (e.g., electric water heaters, HVAC systems) without plugs, where full disconnection prevents residual voltage risks.
- Compliance with safety standards for commercial/residential circuits needing enhanced protection.
4.Is a double pole 20 amp breaker 40 amps?
No. A double pole 20 amp breaker has a rated current of 20 amps per pole, meaning it safely handles up to 20 amps total (not 40 amps). The 2-pole design ensures both conductors disconnect simultaneously, but the current rating remains 20 amps for the circuit.
5. What types of MCB are available?
Types include B-type (low inrush, lighting), C-type (moderate inrush, motors), D-type (high inrush, transformers), and pole configurations (1P, 2P, 3P, 4P).
6. What is the lead time for MCB orders?
Lead time varies by region: typically 1–2 weeks for standard models. Custom orders may take 3–4 weeks. Contact sales for exact timelines.
7. Do you support OEM for MCB products?
Yes, we offer OEM services, including custom branding, packaging, and specifications tailored to your needs.
8. What certifications do your MCBs have?
Our MCBs comply with global safety standards (e.g., IEC, CE) to ensure reliability and regulatory compliance.
9. How to contact a distributor for MCB purchases?
For local distributor info or bulk inquiries, please contact our sales team via email (cncele@cncele.com) or WhatsApp (+86 18958711903).
