  • INNOVATIVE ARMAT LINE

    ARMAT air circuit breakers — are reliable protection and switching devices for electrical networks and the foundation for comprehensive solutions in industry and energy.

  • WIDE RANGE OF APPLICATIONS

    Designed to improve energy efficiency of any electrical installation: from industrial applications and power generation plants with alternative energy sources to traditional electrical installations of commercial buildings and data centers.

    The design of ARMAT air circuit breakers is thought out to the smallest detail. They are available in three- and four-pole versions, rated for nominal currents from 630 to 6300 A.

  • MULTI-STAGE QUALITY CONTROL

    ARMAT series products undergo multi-stage quality control and meet the strictest Russian and international standards.

Advantages
Ics= 100%Icu
Operation via Modbus RTU, Modbus TCP protocols
3 types of electronic releases
High switching endurance indicators for all breaker frame sizes
3P and 4P
Stable operation at elevated temperatures inside switchgear
Insulation voltage up to 1250 V
Design Features
SWITCHING CAPACITY

Rated ultimate short-circuit breaking capacity (Icu) of ARMAT air circuit breakers reaches 150 kA, which ensures their application on various facilities, including energy-intensive industrial enterprises.

Rated service short-circuit breaking capacity (Ics) of ARMAT line air circuit breakers equals the ultimate (Icu). This allows easy selection of the required ARMAT power circuit breaker model and reliable protection of the most critical loads.

ENDURANCE

Mechanical endurance of ARMAT series air circuit breakers — up to 25 thousand operating cycles, electrical endurance — up to 10 thousand cycles.

Declared values are confirmed by practical tests, which guarantees high reliability of ARMAT air circuit breakers and their long-term trouble-free operation.
