CQM6 Standardgehäuse-Schutzschalter (MCCB) – Hersteller für OEM-Produkte
Der CQM6 MCCB bietet Überlast- und Kurzschlussschutz innerhalb seines veröffentlichten 16–1600A-Bereichs. Die Spezifikation sollte sich an der Systemspannung, der Last, der Leiterkoordination, dem voraussichtlichen Fehlerstrom und den geltenden Vorschriften orientieren – nicht allein am Amperezahlwert.
Produktübersicht
CQM6 is a mccb breaker for AC distribution and protection applications. Its published range covers 16–1600A with 2P / 3P / 4P, depending on frame; CQM6-1600: 3P options. Selection depends on the complete power-system design, including fault level, coordination, conductor ampacity, enclosure conditions and local rules.
Die bereitgestellte Produktspezifikation verweist auf IEC/EN 60947-1, IEC/EN 60947-2, IEC/EN 60947-3 und IEC/EN 60947-4 sowie auf GB/T 14048.1, .2, .3 und .4. Diese Normreferenzen begründen an sich keine Zertifizierung für eine bestimmte Bestellung.
Hauptmerkmale
Typische Anwendungen
Typical applications include commercial, industrial and infrastructure distribution or motor circuits. These are evaluation contexts rather than universal approvals. Confirm the exact frame, voltage, breaking duty, trip unit, accessories and installation method before specification.
Antragsformular und Auswahlhinweis
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.

| Ausschaltvermögen | Klassen C/S/M/H/L, mit Icu bis zu 100kA für die aufgeführten CQM6-1600- und 660/690V-Konfigurationen; überprüfen Sie den genauen Rahmen und die Spannung. | Voraussichtlicher Kurzschlussstrom am Installationspunkt |
Feste vs. einstellbare Absicherung
Ein fest eingestelltes thermisch-magnetisches Schutzelement kann sich für ein stabiles Design eignen, während eine einstellbare Auslöseeinheit bei der Koordination hilfreich sein kann, wenn die Projektplanung Einstellungen vor Ort vorsieht.

MCCB vs. MCB
Ein Leistungsschalter für Niederspannung (MCCB) wird in der Regel hinsichtlich höherer Ströme, des Kurzschlussstromvermögens oder der Flexibilität bei der Auswahl von Zubehör bewertet; ein Miniatur-Leistungsschalter (MCB) kann für kompakte Endstromkreise besser geeignet sein.

Anleitung zum Bestellen
- State the exact model: CQM6.
- Provide frame and rated current within the published range: 16–1600A.
- Confirm poles: 2P / 3P / 4P, depending on frame; CQM6-1600: 3P.
- Specify the trip unit or protection function: thermal-magnetic trip.
- Bitte geben Sie die Systemspannung, die Frequenz, den Anwendungsbereich, das erwartete Kurzschlussstromniveau, den Zielmarkt und die Menge an.
- Führen Sie die erforderlichen Zubehörteile, Anschlüsse, Dokumente sowie alle zugelassenen OEM-/ODM-Kennzeichnungs- oder Verpackungsanforderungen auf.
Installations- und Koordinationskontrollen
- Verwenden Sie ausschließlich die spezifische Modellzeichnung und die dazugehörigen Anweisungen; leiten Sie keine Schlussfolgerungen hinsichtlich der Klemmenpositionen, der Versorgungsrichtung oder der Zubehörkompatibilität aus einem anderen Leistungsschalter ab.
- Überprüfen Sie das Leitermaterial und den Querschnitt anhand der Schaltungsdimensionierung, der Klemmendaten, der Temperatur sowie der Gruppierung.
- Bestätigen Sie die Kurzschluss- bzw. Fehlerstrombelastbarkeit der Schaltgeräte, die Koordination zwischen vorgeschalteten und nachgeschalteten Komponenten, die Gehäusebedingungen, die Höhe über dem Meeresspiegel sowie die Freiräume.
- Installation, Isolierung, Prüfung und Wartung dürfen nur von qualifiziertem Personal gemäß den geltenden Vorschriften durchgeführt werden.

For CQM6 projects, CHAC can review private-label marking, packaging, approved appearance options, published 16–1600A electrical configurations and technical-document requirements. Requests outside the published range are subject to engineering evaluation, testing, minimum order quantity and project feasibility.

CQM6 Product FAQ
What is the CQM6 MCCB used for?
The CQM6 is specified for overload and short-circuit protection in AC systems at the voltage listed for the ordered frame within the published 16–1600A range. Suitability depends on the fault study, conductor coordination, enclosure and local rules.
How does the CQM6 molded case circuit breaker work?
The protection mechanism responds to the fault conditions stated for this model: overload and short-circuit protection. Trip behaviour, settings and interruption duty must be checked against the ordered frame and product instructions.
How do I choose the CQM6 rated current and poles?
Start with the design current and conductor calculation, then choose a published current within 16–1600A and poles from 2P / 3P / 4P, depending on frame; CQM6-1600: 3P. Neutral treatment, fault level, ambient conditions and coordination also need review.
What breaking capacity should I check on the CQM6?
Use the declared C/S/M/H/L classes, with Icu up to 100kA for the listed CQM6-1600 660/690V configurations; verify the exact frame and voltage for the exact frame, voltage and configuration. The prospective short-circuit current at the installation point must be within the applicable duty; a larger ampere value alone is not a selection rule.
Can the CQM6 replace an MCB or an earth-leakage device?
An MCCB is not automatically a like-for-like replacement. The CQM6 provides overload and short-circuit protection; residual-current protection, DC interruption, adjustable settings and other functions must be confirmed separately from the project requirement.
How should the CQM6 be installed and tested?
Use only the exact model drawing, terminal identification and accessory instructions. A qualified person should verify isolation, conductor size, torque, clearances, settings, fault duty and functional tests before energising the circuit.
Confirm the Right CQM6 Configuration
Send the frame, rated current, poles, protection function, system voltage, expected fault level, destination market and quantity. CHAC will review the request against the published model range.
