The ABB SH 204 6 KA 4 Pole Miniature Circuit Breaker is a high-performance electrical protection device designed to safeguard four-phase circuits from overloads, short circuits, and other electrical faults. Ideal for both residential and commercial applications, this breaker offers superior safety and ensures the protection of electrical equipment, reducing the risk of damage and improving system reliability.
With a robust 6 KA breaking capacity, the SH 204 is capable of handling high fault currents, effectively interrupting power in the event of an overload or short circuit. This helps to prevent damage to sensitive equipment, minimize fire risks, and maintain the integrity of your electrical infrastructure.
The breaker features an advanced thermal-magnetic trip mechanism that provides dual protection. The thermal component offers protection against prolonged overloads, while the magnetic trip mechanism reacts instantly to short circuits, ensuring fast disconnection of power. This combination ensures precise and rapid fault detection, which is crucial for maintaining safety.
The ABB SH 204 is engineered with a compact design, allowing for easy installation in environments where space may be limited. Its high-quality construction ensures reliability and durability, even in demanding conditions, making it an excellent choice for power distribution systems, motor protection, and industrial control panels.
With its high breaking capacity and versatile protection features, the ABB SH 204 6 KA 4 Pole Miniature Circuit Breaker is an essential component for any electrical system requiring enhanced safety and reliable fault protection.
