NSX Moulded Case Circuit Breaker

The CDADA DAM6 Series is a low-voltage moulded case circuit breaker for AC 50/60Hz distribution networks. Depending on the selected frame and trip unit, it covers rated-current options from 12.5A to 1600A and rated operating voltage up to 690V. It protects lines and electrical equipment against overload and short-circuit conditions, and can support infrequent motor starting and motor overload, short-circuit and under-voltage protection.

For buyers searching for an NSX series MCCB, DAM6 can be evaluated as an NSX MCCB replacement option for retrofit or new-panel projects. Confirm the existing breaker frame, rated current, pole count, terminal arrangement, mounting mode, trip unit, accessories and required breaking capacity before purchase.

Technical Parameters

The exact service breaking-capacity kA value depends on frame, voltage and breaking-capacity code. Request the final model data sheet before ordering.

Product Features and Applications

Flexible Trip UnitsThermal-magnetic and electronic options support different protection and panel-design requirements.

Industrial DistributionSuitable for evaluation in factory, commercial-building, infrastructure and low-voltage switchboard projects.

Remote FunctionsSelected electronic and communication configurations can support status indication, measurement and remote open/close/reset functions.

Retrofit AccessoriesAuxiliary, alarm, shunt, under-voltage, motor and rotary-handle accessories can be specified for panel integration.

Production, Quality and Factory Support

Shanghai DADA Electric Co., Ltd. presents CDADA as a China manufacturer and supplier of low-voltage electrical products. The official website describes a 52,400m² factory, nine automated production lines, ISO 9001-certified processes, more than 60 patents and annual production of more than three million breakers.

Company-level credentials should not be treated as automatic certification of every DAM6 configuration. Ask CDADA for the applicable certificate, test report, product data sheet and inspection records for the exact NSX MCCB replacement model and accessories in your order.

Packing, Shipping and Procurement

Before order confirmation, request the packing specification, moisture-protection method, carton or pallet details, quantity per carton, gross weight, loading plan, lead time and destination-port arrangement. The company website lists EXW, FOB and CIF among its supply-chain terms; the applicable Incoterm, freight and insurance should be confirmed in the quotation.

● Existing breaker brand and model, if this is a replacement project

● Rated current, frame size, voltage and frequency

● 3P or 4P, Icu/Ics and breaking-capacity code

● Thermal-magnetic or electronic trip unit

● Fixed or plug-in mounting and front/rear connection

● Accessory list, quantity, destination port and preferred Incoterm

Installation, Operation and Maintenance

● Installation and wiring must be completed by qualified personnel.

● Do not operate the breaker with wet hands or modify factory-set characteristics without authorization.

● If the breaker trips because of a fault, identify and remove the fault before reclosing.

● Insulate exposed incoming wires and copper busbars to reduce phase-to-phase arc risk.

● Inspect approximately every six months with power isolated; check the mechanism, insulation and mounting surfaces, and remove dust.

● Protect the breaker from moisture and impact during storage, transport and operation.

NSX MCCB Replacement Checklist

FAQ

Is this an original Schneider NSX breaker?

No such claim is made here. The product is the CDADA DAM6 Series MCCB and may be evaluated for an NSX replacement project after technical comparison.

Can DAM6 replace every NSX MCCB directly?

No universal drop-in compatibility should be assumed. Confirm frame, current, poles, terminals, mounting, dimensions, trip unit, breaking capacity and accessories.

What current ratings are available?

The catalogue lists DAM6 frame ratings of 100A, 160A, 250A, 400A, 630A, 1250A and 1600A, with detailed rated-current options depending on the frame.

Are 3P and 4P versions available?

Yes. The catalogue lists 3P and 4P versions. Confirm the neutral-protection arrangement for the project.

Are electronic and communication functions available?

Electronic trip units, LCD options and RS485 MODBUS-RTU communication are described in the catalogue. Availability depends on the selected configuration and communication module.
