ABB System Pro M Compact S200M Miniature Circuit Breaker, 2-Pole, 50 A, Type D, 440 V ac AC, 125 V dc DC, 15 kA Breaking

This miniature circuit breaker (MCB) is a high-performance protective device designed for demanding electrical systems. With a 2-pole configuration and a 50A current rating, it provides robust protection against overloads and short circuits in both commercial and residential applications.

• Type D tripping characteristic for circuits with high inrush currents (motors, transformers, industrial loads)
• Rated for 400V AC with a high breaking capacity of 15kA for enhanced safety
• 2-pole design provides comprehensive protection for both live and NEUTRAL conductors
• Toggle switch actuator allows quick and reliable reset operation
• Thermal and electromechanical tripping mechanisms ensure precise overload and short circuit protection

• Commercial and residential electrical distribution systems
• Protection of circuits with high inrush currents such as motors, pumps, and HVAC systems
• Suitable for control panels, switchboards, and industrial installations
• Effective in environments requiring high breaking capacity and dependable circuit protection

Type D MCBs trip between 10 to 20 times the rated current, making them suitable for circuits with very high inrush currents such as motors, transformers, and welding equipment.

Yes, while it is often used in commercial and industrial setups, it can also be applied in residential systems where high inrush current protection is required.

The dual tripping mechanism ensures precise protection: thermal tripping responds to overloads, while electromechanical tripping reacts instantly to short circuits, providing comprehensive circuit safety.
