The equipment features a high-strength, fully integrated steel chassis with precision-sealed panels, finished with an anti-static, anti-rust, and corrosion-resistant coating for enhanced durability and long-term reliability.
User-centric design with an ergonomically positioned control panel and operation buttons on the right-hand side, offering convenient operation and a sleek, modern appearance.
Equipped with a dedicated protective enclosure, ensuring all tests are performed safely within a fully shielded environment for optimal operator protection.
Fully compatible with the production and testing of 3P–4P molded case circuit breakers (MCCB) in the 63A to 125A specification range, meeting diverse production requirements.
Featuring an intelligent automatic clamping system, the equipment supports precise opening and closing operations. The test current adjusts according to the product configuration—conductive when closed, non-conductive when open—executing continuous cycles with adjustable load current ranging from 1A to 125A. The number of test cycles can be freely set through the intuitive touchscreen interface.
Equipped with four pairs of fixtures to adapt to various product types, the system supports single-product testing at a time with a dedicated, stable power supply to ensure accuracy and consistency.
