Round type leakage detection residual current transformer

S/N: LO-ZRCT-XX

Product overview:

The LO-ZRCT-XX series residual current transformers are primarily used in low-voltage distribution systems such as 380V and 660V, or in densely packed drawer cabinets, to continuously monitor and detect residual currents at installation nodes in corresponding circuits. The outer shell of this series is made from environmentally friendly flame-retardant ABS engineering plastic, and it uses high magnetic permeability nanocrystalline soft magnetic material. Combined with a reasonable structural design and rigorous production processes, the product features high precision, good balance performance, small size, high insulation strength, strong impact resistance, and easy installation, making it reliable and stable for indoor use.

Additionally, the structural design incorporates customer feedback, with the fixing feet designed to be retractable into corresponding slots before transport and installation. This prevents damage to the fixing feet before installation, reducing the risk of product failure, and also helps lower packaging and transportation costs. This series includes 11 different models, suitable for monitoring residual currents in cable circuits or copper busbar circuits, with a minimum detectable leakage current of less than 5mA and accuracy meeting or exceeding the national standard GB14287.2. The balance characteristics can be customized according to usage requirements. The color of the product casing can be customized to meet different color scheme requirements specified by customers.

Features:

Resin casting process, excellent waterproof and moisture-proof performance
It has strong overload capability and can be overloaded 50 times the rated current for a long time if necessary.
Excellent balance characteristics, small size products meet the detector alarm threshold requirement of 20mA
High precision: precision level 0.5/1.0/3, optional compact design, small size
