ABB S400M Series MCB, 3 Poles, 10A Current Rating - S403M-C10 This 3-pole miniature circuit breaker is engineered to provide dependable protection against overloads and short circuits. It features a C-type tripping characteristic and is ideal for circuits with significant inrush currents. Features & Benefits • Provides accurate protection against overloads and short circuits through a combination of thermal and magnetic trip mechanisms
• Incorporates a trip-free mechanism that prevents the breaker from being manually reset while tripped, enhancing safety
• Designed with clear, user-friendly labelling for easy identification and operational ease
• Features a temperature compensation mechanism that adjusts tripping characteristics based on ambient temperature, ensuring consistent performance
• Includes a snap-on design for quick and easy installation on standard DIN rails Applications • Used in control panels for heating and cooling systems to safeguard against electrical faults
• Applied in lighting systems to protect circuits driving high-intensity lamps and LED fixtures
• Utilised in motor control panels to shield circuits powering various industrial equipment such as pumps and fans
• Employed in distribution boards for commercial and residential installations to ensure reliable circuit protection What protection does the thermal element provide? The thermal element offers overload protection by activating the breaker when excess current heats it beyond a set threshold How does the magnetic element enhance circuit protection? The magnetic element provides rapid tripping during short circuits by responding to sudden spikes in fault current Is this circuit breaker suitable for handling high inrush currents? Yes, it is designed to accommodate high inrush currents typically associated with inductive loads
