Discover the Siemens MCB Lineup — Engineered for Any Scale
The siemens mcb lineup is built to handle everything from basic home circuits to demanding industrial environments.
The 5SL series is tailored for standard residential and light commercial use — it covers typical needs like lighting, HVAC, and socket protection with B and C tripping curves, ratings up to 63 A, and 10 kA breaking capacity. It’s easy to install and works seamlessly with Siemens busbars and modular accessories.
For heavier loads, the 5SY series steps in. Designed to handle short circuits up to 25 kA and available with selective tripping features, it’s well-suited for industrial applications such as motor protection, conveyor lines, and high-load factory equipment.
When panel space is limited, the compact 5SP4 series becomes a reliable solution. It offers up to four poles and allows both horizontal and vertical mounting, which is especially useful for export-ready or space-constrained projects.
The SENTRON 5SV series takes it even further, combining circuit protection with smart features like real-time diagnostics, communication interfaces, and system logic — ideal for smart buildings, energy-monitored sites, and critical infrastructure. Many Siemens MCBs also support both 230/400 V AC and DC applications, making them a flexible choice for solar installations, EV charging stations, and other modern electrical networks.

Where Siemens MCBs Make the Difference — From Homes to Heavy Industry
Let’s take a closer look at
Siemens miniature circuit breakers (MCBs) aren’t just technical parts — they’re what keep modern electrical systems safe, scalable, and smart. Thanks to their versatility and robust design, these breakers are used across the board: from cozy homes and apartment blocks to large-scale industrial operations and cutting-edge smart buildings.
Where Siemens MCBs Fit — From Homes to High-Load Networks
Residential Use
Whether you're wiring up a single house or an entire apartment block, the Siemens 5SL series delivers steady, reliable protection for everyday circuits. From lights and outlets to fridges and A/C units, they handle standard loads with ease. Homeowners get peace of mind, while installers appreciate the speed and simplicity of mounting and wiring.
Commercial and Public Buildings
In schools, hospitals, retail spaces, and offices, the demands on electrical systems are higher — and Siemens MCBs rise to meet them. The 5SY and SENTRON series are built for these environments, offering selective tripping and high short-circuit capacity. That means fewer disruptions, smoother operation, and equipment that stands the test of time even under pressure.
For example!
Think of a hospital where uninterrupted power matters. The right breaker here doesn’t just protect—it ensures life-saving equipment keeps running.
Industrial Systems and OEM Machinery
Siemens breaker built for long-term use, they’re rugged enough to withstand vibration, heat, and harsh conditions without missing a beat. Their modular design, universal DIN-rail compatibility, and global certifications make them an easy fit for OEMs developing machinery for international markets. And with smarter models supporting automation and diagnostics, they’re ready for Industry 4.0 — where even your breakers know when to raise the alarm.
Siemens mcb are built to handle the tough stuff: motors, power panels, transformers, and high-demand equipment that runs around the clock. Their modular build and easy DIN-rail mounting make them a go-to choice for OEMs, especially when the final product needs to meet strict international standards. Whether you're outfitting a factory floor or designing machines for export, these breakers are built to deliver — day in, day out.
Smart Buildings and Energy-Managed Projects
The SENTRON 5SV series is designed for new era, with built-in support for communication modules, remote diagnostics, and real-time system monitoring.
