Split Core Current Transformer Outdoor Waterproof TRCTFS Series CT Protection Grades IP66 IP67 IP68

The Outdoor Waterproof Current Transformer is a pivotal component for AC power systems, engineered to deliver reliable current measurement, signal sampling, and protection in harsh outdoor environments. Built on electromagnetic induction principles, it steps down high primary currents (0-50000A AC) to manageable values (1A/5A or customized voltages) for metering and microcomputer protection systems . Boasting an IP67/IP68 rating, its robust design features high-quality epoxy resin vacuum casting and UV-resistant flame-retardant plastic housing (ABS/PC), effectively withstanding moisture, heavy rain, and extreme temperatures (-40℃ to 70℃) . The high-permeability silicon steel core minimizes magnetic loss

Product Features

Easy Retrofit Installation & IP-Rated Enclosure – The hinged core allows clamping around existing conductors without disconnection. A sealed housing (typically IP65/IP67/IP68) protects against dust and water ingress.

Durable & Weather-Resistant Construction – Features UV-resistant, corrosion-resistant materials suitable for long-term exposure to rain, humidity, and temperature variations.

Maintains High Measurement Accuracy – Provides reliable and accurate current measurement (typically Class 0.5/1.0) despite the protective enclosure and challenging environmental conditions.


Product Application

Outdoor Power Monitoring – Measuring current in meter cabinets, distribution boxes, and on overhead service lines exposed to weather.
Renewable Energy Systems – Monitoring output current of solar PV combiners, wind turbine circuits, and other outdoor generation equipment.
Industrial & Marine Environments – Current measurement in damp locations like wastewater treatment plants, pumps stations, docks, and shipboard electrical panels.

Practical Application

* Mainly applied in outdoor power distribution system renovation projects, featuring splash-proof performance and short-term water immersion resistance.

* Easy to install without disassembling the primary busbar; live-line operation is also available (with proper electrical protection measures in place).

* Can be used in conjunction with relay protection, measurement, and metering devices.

* It does not affect the normal on-site power supply, saves manpower, material resources, and financial resources for the user's renovation project, and improves efficiency.

Installation Precautions

* Before the silicon steel core is closed ,ensure that the end face

of the incision is clean ,free of stains and impurities;It must be treated with anti-rust agent;

* Use a torgue wrench (electric /pneumatic ) when tightening the screws and set the torque to a reasonable range .
