We have our own manufacturing facilities with a combined production capacity of over 2,000 units per year. Having our own metal workshop equipped with state-of-the-art machinery allows us
Over the years we supplied about 1.500 circuit breakers for voltage 110, 220 and 500 kV to the Russian market.
Russian circuit breakers commonly use high-purity copper or silver-copper alloys to maximize electrical conductivity and minimize resistive heating. In premium models—particularly air circuit breakers and high-capacity molded case breakers—contacts are often silver-plated.
GOST Standards: The primary Russian certification system (e.g., GOST R 50030.2 / IEC 60947-2) governs low-voltage switchgear and controlgear. IEC Standards: International benchmarks such as IEC 60898-1 (for household MCBs) and IEC 60947 (for industrial breakers) ensure global compatibility.
Weatherproof Enclosures: Outdoor breakers must be installed in NEMA 3R, 4, or 4X-rated enclosures that protect against rain, snow, ice, and dust. IP Ratings: Look for an Ingress Protection (IP) rating of at least IP55 (dust protected and water jet resistant) for reliable outdoor performance.
