Moulded Case Circuit Breakers 3VA SENTRON

Moulded Case Circuit Breakers (MCCBs) from the Siemens 3VA SENTRON series are high-performance devices designed for reliable protection of electrical installations. These circuit breakers are available in various frame sizes (100, 160, 250, 400, and 630 A) and breaking capacity classes (N, S, M, H, C, L) with Icu ratings from 25 kA to 150 kA at ...

Moulded Case Circuit Breakers (MCCBs) from the Siemens 3VA SENTRON series are high-performance devices designed for reliable protection of electrical installations. These circuit breakers are available in various frame sizes (100, 160, 250, 400, and 630 A) and breaking capacity classes (N, S, M, H, C, L) with Icu ratings from 25 kA to 150 kA at 415 V AC. They come in 2-pole, 3-pole, and 4-pole configurations, offering advanced protection features such as thermal-magnetic (TM) and electronic trip units (ETU) with L, LI, LSI, LSIG, and LIG characteristics. Key technical parameters include adjustable overload protection (Ir), short-circuit protection (Ii or Isd), and ground-fault protection. Accessories like bus connectors, circular conductor terminals, and plug-in conversion kits enhance flexibility for various mounting and wiring requirements.

These MCCBs are primarily used in industrial and commercial power distribution systems, including main switchboards, sub-distribution boards, and motor control centers. They are ideal for protecting cables, transformers, motors, and other critical equipment against overloads and short circuits. Typical applications include manufacturing plants, data centers, commercial buildings, and infrastructure projects where high fault currents and selective coordination are required. The 3VA series supports both fixed and plug-in mounting, making it suitable for panel builders and system integrators.

The Siemens 3VA SENTRON series complies with international standards IEC 60947-2 and EN 60947-2, ensuring global acceptance and safety. These breakers are fully compatible with Siemens SENTRON accessories and communication modules, including PROFIBUS and PROFINET interfaces for integration into automation systems. They also work seamlessly with other Siemens components like contactors, relays, and busbar systems, providing a complete solution for electrical distribution.

At Electric Automation Network, we offer the full range of Siemens 3VA MCCBs with real-time pricing and expert technical support from our engineering team. Our global express shipping ensures fast delivery to any location worldwide. We provide detailed documentation for each article, including datasheets and wiring diagrams, to assist with selection and installation. Whether you need standard breakers or customized configurations, our specialists are ready to help optimize your power distribution system.
