CHINT supplier in Romania
Low-voltage contactors and circuit breakers
Founded in 1984 · Headquarters: Yueqing, China
Who is CHINT and what does it make?
CHINT is a Chinese manufacturer of low-voltage electrical switchgear, founded in 1984 in Yueqing, Zhejiang province, with operations in more than 140 countries. The low-voltage range covers contactors (NC1 series), modular circuit breakers (NXB-63, NB1-63), moulded case circuit breakers (NM8N, for secondary distribution) and air circuit breakers for main distribution (NXA series), to which are added complete electrical panels, power transformers (including a 1000 kV/1000 MVA UHV transformer, which passed type and routine tests), charging systems for electric vehicles and gas and electricity meters. We can quote individual components or batches for electrical panels.
The CHINT low-voltage range exists in both IEC and UL versions, for different markets. The NG7-38 series of medium-voltage switchgear has ETL approval for the North American market.
For projects in Romania where the electrical panel has to be equipped quickly and at a competitive cost per component — industrial halls, EV charging stations or secondary distribution installations — the CHINT range covers most standard components without tying the panel to a single brand.
What do we supply from the CHINT range?
| Product | Description |
|---|---|
| NC1 series contactors | AC contactors for controlling motors and industrial circuits, used as a basic element in automation panels. For a quotation we need the rated current and the control coil voltage. |
| NXB-63 / NB1-63 modular circuit breakers | Miniature circuit breakers (MCB) to IEC, for protecting final distribution circuits — sockets, lighting, single-phase and three-phase circuits in electrical panels of medium complexity. |
| NM8N moulded case circuit breakers | Circuit breakers (MCCB) for secondary distribution, with overload and short-circuit protection settings, used to supply secondary panels or machines with a higher power than final circuits. |
| NXA series air circuit breakers | Air circuit breakers (ACB) for main power distribution, sized for high currents at the incoming supply of the main panel of a building or industrial hall. |

How do we supply CHINT in Romania?
To be clear: CHINT components are not held as our own stock; we work from the manufacturer's technical documentation for the technical parameters above. We bring in components and CHINT-equipped panels to order through supply channels in the EU, usually in 1–4 weeks. For a quotation we need the rated current, the working voltage, the number of poles and whether the product must be IEC or UL certified, depending on the destination market. We do not design the complete electrical panel — we supply the components according to the bill of materials received from the designer or electrician.
We do not design the electrical panel, and availability for medium-voltage components or large transformers is confirmed in the quotation.
Frequently asked questions about CHINT
What is the difference between the CHINT NXB-63 and NB1-63 circuit breakers?
Both are modular circuit breakers (MCB) with a rated current of up to 63 A, but they belong to different construction series, with tripping curves and breaking characteristics adapted to different installation requirements. Checking the data sheet of each series, the permitted short-circuit current and the tripping curve is recommended before the final choice for an electrical panel.
What is the CHINT NC1 series contactor?
NC1 is the basic series of AC contactors in the CHINT range, used for controlling electric motors and other similar industrial loads. It is available in several sizes, depending on the rated current of the load controlled, and is integrated in electrical panels alongside breakers from the NXB or NM8N series.
What is an NXA series air circuit breaker (ACB)?
NXA is the CHINT series of air circuit breakers, used for the protection and control of high-power electrical circuits, at the level of main distribution panels. Compared with modular or moulded case breakers, the NXA series covers higher rated currents, and is suitable for the main incoming supply of a large industrial electrical panel.
Do you supply CHINT electrical equipment in Romania?
Yes, we bring in products from the NC1, NXB, NM8N and NXA series and the related accessories presented above to order, according to the manufacturer's catalogues; this range is brought in on request. The lead time is usually 1–4 weeks, depending on the model and the quantity ordered. For a quotation, send the rated current required and the type of application.
What do I need to send for a CHINT circuit breaker quotation?
It is useful to specify the rated current required, the number of poles, the tripping curve wanted and the rated voltage of the electrical installation. This information allows the correct choice between the NXB, NB1, NM8N or NXA series, avoiding wrong sizing of the electrical protection for the circuit concerned.
How do I request a CHINT quotation?
Send the CHINT code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
