ABB System Pro M Compact S200 Miniature Circuit Breaker, 3+N-Pole, 20A, Type D, 400V ac AC, 100 V dc DC, 6 kA Breaking

This miniature circuit breaker provides overcurrent protection for three-phase systems with a NEUTRAL conductor in installations. It combines thermal and electromechanical tripping to respond to prolonged overloads and sudden surges while being suitable for rail-mounted distribution panels. The device is intended for installations requiring co-ordinated protection up to medium fault levels and for switching operations using a manual toggle.

• 6kA breaking capacity limits fault energy exposure
• Type D tripping handles high inrush currents
• 20A rating supports moderate circuit loads
• Screw terminals ensure secure conductor connections
• DIN-rail mounting enables fast panel installation

• Suitable for motor start-up circuits with high inrush
• Ideal for small distribution boards in workshops
• Used with three-phase lighting and heating circuits
• Can be used for protection in modular control panels
• Suitable for AC and DC hybrid circuit arrangements

It combines thermal elements for overloads and an electromechanical magnetic release for short-circuit clearing.

It clips onto a standard DIN rail and connects via screw-type line and load terminals.

The device body has IP40 protection at the front and IP20 for access to live parts.

It is rated for use up to 400V AC and up to 100V DC.

It is supplied as a three-pole unit with an integrated NEUTRAL conductor (3+N).
