Reliable Protection: The FATO DZ47sLE-63 Earth Leakage Circuit Breaker (ELCB) AC delivers robust dual protection against electric shock hazards and short-circuit faults, ensuring personnel safety and system integrity. Its integrated trip mechanism combines residual current detection (≤30mA sensitivity) and instantaneous magnetic tripping, effectively isolating faults while maintaining a secure operational environment. Wide Application Scope: Designed as a versatile miniature circuit breaker (MCB), it supports 1P+N, 2P, 3P, 3P+N, and 4P configurations, accommodating diverse electrical networks ranging from residential single-phase systems to industrial three-phase installations. The modular design ensures compatibility with global wiring standards, making it ideal for panel builders and system integrators. Durability & Cost Efficiency: Engineered with industrial-grade thermoplastics and silver-alloy contacts, this ELCB guarantees a minimum service life of 20,000 mechanical operations under IEC 60947-2 compliance. Backed by a 2-year warranty, its maintenance-free design reduces downtime and lifecycle costs, offering exceptional long-term value. Global Compliance: Certified to IEC 61009-1 (RCCB) and EN 60898-1 (MCB) standards, the device meets stringent international safety and performance requirements. Its universal design ensures seamless integration into both 50Hz and 60Hz grids, aligning with regional regulations across 230V/400V markets in Asia, Europe, and beyond. Customization Flexibility: Users can select optimized configurations for frequency (50Hz/60Hz) and voltage ratings (230V/400V), enabling tailored solutions for HVAC systems, machinery control panels, or renewable energy installations. Optional auxiliary contacts and shunt releases further enhance adaptability to complex automation scenarios.

The KXAIS-12 series Solid Insulated Ring Main Unit Rmu Electrical Switchgear is a fully insulated, fully sealed, and anti condensation ring main unit equipment that is based on solid sealing and vacuum insulation technology, and is independently developed using epoxy resin (APG process) to pour the three position switch (isolation, grounding), circuit breaker vacuum arc extinguishing chamber, and main circuit primary conductive components together to form the insulation component body. It is assembled from insulated busbars and other insulation connectors to form a fully insulated, fully sealed, and anti condensation ring main unit.

The GW16 type 72.5KV 4000A Vertical knee-type disconnector boasts a sleek and modern design, combining compactness with a visually appealing aesthetic. Notably reliable and economical, it offers a practical solution for sites with varying entrance and exit line heights, as the vertical contacts do not occupy additional space when tripped.

The Drawer type low-voltage switchgear ensures that each functional unit is distinct from the busbar or cable, creating three separate areas for efficient power distribution. This design also incorporates isolation measures between functional units, contributing to the overall reliability and safety of the switchgear. As a result, drawer-type switchgear is widely used in industrial and mining enterprises, high-rise buildings, and centralized control distribution centers that require high power supply reliability. The switchgear's closed steel plate shell houses withdrawable drawers containing electrical components for incoming and outgoing circuits, allowing for easy maintenance and customization.

12KV Indoor Medium Voltage Vacuum Circuit Breaker is a high-voltage solution for indoor applications, featuring a rated voltage of 12KV and a frequency of 50Hz for three-phase AC systems. This product, known for its reliability, complies with the GB1984-89 standard. The design of this product is available in two configurations: the switch body and operating mechanism are integrated, and a modular version where the switch body and operating mechanism are separate. The integrated design is denoted as the ZN28-12 type, while the modular design is referred to as the-12 type, suitable for use in fixed switches such as GG-1A(Z) and XGN2A10(Z). This product can be paired with DC electromagnetic types CD17 and CD10A, as well as spring energy storage types CT17 and CT19.
