Import Clamp On Current Transofrmer 500a — Buy in Bulk from Supplier in China

The Clamp On Current Transofrmer 500A is a bus‑bar mounted CT designed for installation in confined spaces without disconnecting the primary conductor. It is rated for a primary current of 500 A with a maximum continuous input of 550 A at 45‑66 Hz, and delivers an AC output voltage of approximately 1 mV. Accuracy figures include ±0.3 % amplitude reading, ±0.01 % full‑scale, and a phase accuracy of ±0.5 ° over 10‑100 % IIn. The device complies with EN 61010‑2‑032:2002 CATIII safety, EMC class A standards and operates at up to 600 V crms.

The clamp‑on mechanism uses a folding pressure holder that grips a Ø46 mm conductor, eliminating the need for bus‑bar removal. The iron‑core construction offers excellent linearity and a typical insulation class B, with a standard burden of about 5 VA for a 500 A class CT. Temperature coefficient is 0.02 % / °C and the dielectric strength reaches 5312 V A C rms for 15 seconds, matching industry expectations for high‑precision measurement devices. Typical environmental limits are 0 °C to 50 °C and 80 % relative humidity, with storage allowed from - 10 °C to 60 °C.

Primary users include power‑quality monitoring firms, smart‑logger manufacturers and utilities that need distributed current measurement. The CT is suited for projects that require quick, reliable installation in tight enclosures such as switchgear panels. Buyers should request formal quotations, confirm the minimum order quantity, and agree on Incoterms and payment conditions directly with the supplier before proceeding.

Shen Zhen Chuang Yin Technology Co., Ltd. is located on Song Ping Road in the high‑tech industrial zone of Shenzhen, Guangdong, China (postal code 518057). The company holds a harbor‑tier verification on the platform, although its response rate is currently recorded as 0 % with no average response time available, indicating that buyers should initiate contact well in advance of any deadline.

The supplier lists a clamp‑on current transformer capable of measuring up to 550 A without removing the primary conductor. No additional certifications, production capacity or lead‑time figures are disclosed, so interested importers should ask the supplier to provide test reports and confirm any required compliance documentation.
