FAQ
How many amps is a 2 pole 100 amp breaker?
A 2-pole 100 amp breaker has a total current rating of 100 amps, with each pole carrying 100 amps. It is designed for 240V single-phase circuits, providing balanced protection across both line conductors.
How many double pole breakers can I put in my 100 amp panel?
The number depends on your panel’s physical slot capacity and load calculation. A 100 amp panel typically supports 10–20 total circuit slots (varies by model). Since double-pole breakers occupy 2 slots each, the maximum is generally 5–10, but never exceed the panel’s total ampacity or manufacturer’s limits.
What is a double 100 amp breaker used for?
A double 100 amp breaker is used to protect high-power 240V appliances or systems, such as central air conditioners, electric water heaters, large motors, or subpanels. It simultaneously disconnects both hot wires, ensuring safe isolation for heavy electrical loads.
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.
Do you support OEM for MCB products?
Yes, we offer OEM services, including custom branding, packaging, and specifications tailored to your needs.
What certifications do your MCBs have?
Our MCBs comply with global safety standards (e.g., IEC, CE) to ensure reliability and regulatory compliance.
How to contact a distributor for MCB purchases?
For local distributor info or bulk inquiries, please contact our sales team via email ([email protected]) or WhatsApp (+86 18958711903).
