CQM6 Standard Molded Case Circuit Breaker (MCCB) Nhà sản xuất OEM

Hướng dẫn đăng ký và tuyển chọn

Use the verified CQM6 values below to create a shortlist, then validate the complete circuit. An MCCB rating does not replace conductor calculations, fault-current analysis, coordination review or local installation requirements.

Hướng dẫn đặt hàng

1. State the exact model: CQM6.
2. Provide frame and rated current within the published range: 16–1600A.
3. Confirm poles: 2P / 3P / 4P, depending on frame; CQM6-1600: 3P.
4. Specify the trip unit or protection function: thermal-magnetic trip.
5. Provide system voltage, frequency, application, expected fault level, destination market and quantity.
6. List required accessories, terminals, documents and any approved OEM/ODM marking or packaging requirements.

Kiểm tra lắp đặt và phối hợp

• Use the exact model drawing and instructions; do not infer terminal positions, supply direction or accessory compatibility from another MCCB.
• Verify conductor material and cross-section against the circuit calculation, terminal data, temperature and grouping.
• Confirm Icu/Ics or DC fault duty, upstream/downstream coordination, enclosure conditions, altitude and clearances.
• Installation, isolation, testing and maintenance must be performed by qualified personnel under applicable rules.

Selection Guide

Danh sách phụ kiện

CHAC offers a right-side auxiliary switch, a left-side shunt release and a left-side undervoltage release.

For accessory codes 220, 320, 240, 340, 270 and 370, the auxiliary switch can provide two contact pairs. Specify this requirement when ordering.

For accessory codes 250 and 350, the shunt release and undervoltage release on frames 400 and above are available only for 3-pole circuit breakers.
