ABB S400M Series MCB, 1 Pole, 10A Current Rating - S401M-C10

This miniature circuit breaker (MCB) is designed for effective electrical protection. Featuring a rated current of 10A, it is equipped with both a thermal and electromechanical tripping mechanism. With a width of 18mm, length of 91mm, and depth of 82mm, it utilises DIN rail mounting, making it suitable for streamlined installation.

Features & Benefits

• Type C circuit breaker for short-circuit protection

• Rated breaking capacity of 10kA for enhanced safety

• Compact design caters to space-limited installations

• Screw terminal type supports diverse connection needs

Applications

• Ideal for critical power applications requiring consistency

• Effective in environments needing strict safety standards

What is the purpose of the C-type tripping characteristic?

The C-type characteristic is designed to manage high inrush currents, providing reliable protection without frequent tripping

How does the thermal element provide overload protection?

The thermal element responds to excess current by heating up, which triggers the breaker to protect the circuit from overloads

Is this circuit breaker designed for easy installation?

Yes, it features a snap-on design for quick and straightforward installation on DIN rails
