CY –QCT04-12 (10A) Clamp-on Current Transformer

‘QCT04-12’ Clothes-pin clamp-on current transformer is easily installed in small spaces (measurement environment) and no need to remove the main bus or cable. The sensor head adopts the clothes-pin structure, which protects the user from direct contacting with the live body, compliant with the CE standard and meets the 300V CAT safety grade.

General Data:

Operating temperature & humidity: 0 - 50(32 - 122 ° F), 80% RH (no condensate)

Storage Temperature & Humidity: -10 - + 60(14 -140 ° F), 80% RH (no condensate)

Operating environment: indoor, up to 2000 meters above sea level.

Safety level standards: IEC 61010-1: 2001. 300 V CAT III


Features:

Flexible and lightweight, beautiful appearance

Simple and quick installation in small space

Excellent linearity

Maximum measured current is 130A

Application:

General measurement and protection for strong mobility or space-constrained or uninterrupted power systems

Power instrumentation, electronic multi-function energy meter and field calibrator, instrumentation measurement and protection

Attention:


1. Please note that prolonged over current use may damage the product.

2. Do not store or use this product in the environment of directly exposed to sunlight, high temperature or high humidity or condensation. The product may be damaged, the insulation will be deteriorated in these condition.

3. Do not to drop the product or suffer from other mechanical shocks, which may damage the surface of the core and affect the measurement accuracy.

4. Keep the jaws & the core slit without foreign matter, which may affect the clamping action.

5. Holding Clamp Closed When storage, in order to avoid dust or dirt buildup on the core engagement surface, foreign maters may affect the measurement performance.

6. When disconnecting the BNC connector, be sure to rotate the lock before releasing the connector. Pulling the connector or pulling the cable (under lock unreleased) will damage the connector.

7. To prevent damage to the connected instrument, do not connect or disconnect the sensor in the event of charging (working statue) .

8. Note: Only one wire can be clamped in the center of the chuck. If you clamp the single-phase (2-wire) or three-phase (3-wire) cable at the same time, the device will not generate any readings.

9. The above parameters are only for reference as typical data, customer-made is subject to customer’s request.
