SINAVA provides circuit protection solutions for low-voltage electrical distribution systems, covering Miniature Circuit Breakers (MCBs), Molded Case Circuit Breakers (MCCBs), and Air Circuit Breakers (ACBs). As a Circuit Breaker Manufacturer, we support residential, commercial, and industrial projects with circuit breakers designed for different current ratings, protection requirements, and distribution configurations. From branch circuit protection to main power incoming protection, our product range helps customers build reliable electrical distribution systems.
Selecting the right circuit breaker depends on the rated current, operating voltage, prospective short-circuit current, load characteristics, and installation requirements. SINAVA offers three main circuit breaker categories to address different levels of low-voltage circuit protection.
ACB (Air Circuit Breaker) It features large breaking capacity and high rated current. Mainly applied in main power incoming cabinets, responsible for overall circuit protection, overload, short circuit and under-voltage protection of heavy-current power lines.
MCCB (Moulded Case Circuit Breaker) With moderate current range and compact structure. It serves branch circuit protection in distribution boxes, protecting power equipment and industrial circuits against overload and short circuit faults.
MCB (Miniature Circuit Breaker) Small-sized and easy to install. Commonly used in household and light commercial circuits, controlling lighting, socket and small electrical loops to ensure daily power safety.
Choosing a circuit breaker involves more than matching the rated current. The device must be compatible with the electrical system and provide adequate protection under normal operating and fault conditions.
Rated Current and Operating Voltage: Match the breaker's ratings to the connected load and distribution system.
Breaking Capacity: Verify that the rated breaking capacity is sufficient for the prospective short-circuit current at the installation point.
Number of Poles: Select the appropriate pole configuration for the circuit and grounding arrangement.
Protection Characteristics: Consider overload, short-circuit, and other protection functions required by the application.
Installation and Accessories: Check mounting requirements and the availability of compatible auxiliary switches, shunt trips, undervoltage releases, or operating mechanisms where needed.
These factors help distributors, panel builders, contractors, and electrical engineers identify suitable circuit breakers for their projects.
