Among them, the **ABB SH200 Series Miniature Circuit Breaker (MCB)** stands out as one of the most trusted solutions for low-voltage power distribution. Combining compact design, outstanding performance, and advanced safety features, the SH200 series ensures reliable protection for both people and equipment.
## **1. Overview: Compact Size, Powerful Protection**
The **ABB SH200 Series** belongs to the ABB *System pro M Compact* family, covering configurations from **1 pole to 4 poles**, with rated currents ranging from **0.5A to 63A** and voltage ratings up to **230/400V AC**.
It is designed to protect electrical circuits against **overloads and short circuits**, making it ideal for **residential, commercial, and industrial** applications.
Despite its compact structure, the SH200 series offers high performance and durability, providing an efficient and reliable solution for modern distribution panels and control systems.
## **2. Technical Advantages**
### **(1) Accurate Overload and Short-Circuit Protection**
The SH200 series uses a **thermal-magnetic tripping mechanism**, ensuring fast and accurate response to fault currents. The **thermal release** protects against overloads, while the **magnetic release** provides immediate reaction during short circuits — cutting off current flow within milliseconds to minimize damage and fire risk.
Users can select **B, C, or D trip curves**, depending on the load type — from lighting and resistive loads to inductive or motor-driven circuits.
### **(2) High Breaking Capacity for Reliable Safety**
The SH200 series offers a breaking capacity up to **10kA (IEC 60898)** or **15kA (IEC 60947-2)**, ensuring safe operation even under high fault currents in industrial environments.
This high interrupting ability helps maintain system integrity and prevents damage to other connected devices.
### **(3) Long Service Life and Robust Design**
Built with **high-strength flame-retardant materials** and **silver-alloy contacts**, the SH200 MCB ensures stable operation even in harsh environmental conditions.
It features up to **20,000 mechanical operations** and **10,000 electrical switching cycles**, significantly reducing downtime and maintenance costs.
### **(4) Modular Design and Compatibility**
With its **17.5 mm standard module width**, the SH200 series can be easily combined with other ABB accessories such as residual current devices (RCDs), surge protection devices (SPDs), auxiliary contacts, and shunt trip modules.
The **DIN rail mounting** design allows quick installation and flexible system upgrades, supporting seamless integration into ABB low-voltage systems.
## **3. Smart and User-Friendly Design**
Although it is a traditional mechanical circuit breaker, ABB has incorporated user-centric and intelligent features in the SH200 series:
* **Clear ON/OFF indicator** for safe operation visibility.
* **Dual-function terminal design** for both cable and busbar connection, simplifying wiring.
* **Wide range of accessories**, such as auxiliary switches and trip modules, enabling remote monitoring and control.
* **IP20 touch-safe protection**, preventing accidental contact and ensuring operator safety.
These thoughtful details make the SH200 series not only reliable but also flexible for a wide variety of installation environments.
## **4. Typical Application Fields**
### **Residential Distribution**
The SH200 MCBs are widely used in household distribution boards to protect lighting circuits, sockets, and appliances from overloads or short circuits.
### **Commercial and Office Buildings**
In offices, shopping malls, hotels, and hospitals, the SH200 provides safe and reliable branch circuit protection, minimizing the risk of downtime caused by electrical faults.
### **Industrial Control Panels**
In factory automation systems, motor control panels, and PLC circuits, the SH200 series safeguards sensors, control power, and auxiliary circuits from electrical damage.
### **Renewable Energy and Distributed Systems**
SH200 MCBs are also suitable for photovoltaic (PV) systems and energy storage applications, offering secure circuit protection on both AC and DC sides.
## **5. Market Advantages and ABB Brand Strength**
As a global technology leader in electrification and automation, **ABB** ensures that each SH200 MCB meets the highest standards of safety, quality, and performance.
