The W series circular split-core outdoor waterproof current transformer is engineered for superior performance in demanding environments. The primary innovation is its robust waterproof functionality, specifically designed for outdoor utility. A silicone ring seals the magnetic core's cut end face to block rainwater effectively. Its integrated ultrasonic fusion welding shell and epoxy resin casting ensure the secondary side lead wires are protected from moisture infiltration, achieving an impressive IP66 waterproof rating.
Sealed with silicone rings and epoxy resin for outdoor safety.
Easy installation without disconnecting the primary cable.
Accuracy class 0.5 with a wide linear range of 5%~120%.
This transformer is ideal for electrical fire monitoring systems, fire equipment power monitoring, intelligent power consumption systems, and low-voltage power grids. It supports small current grounding systems, relay protection, and motor protection systems for accurate measurement and line monitoring.
