ABB MCB, 10kA Short-Circuit Capacity, IP20 Rating - S400M Series - S401M-B4

Use this MCB from ABB to protect people and equipment in your workspace from the harmful effects of overvoltage. As a type B breaking component, it trips quickly to break the circuit and stop electrical energy whenever it's supplied with between 3 and 5 times the 4A rated load. This makes it a practical choice in lower-powered residential settings as its quick tripping action helps to ensure effective protection when even slight overcurrent faults occur. As part of ABB's innovative SMISSLINE TP plug-in distribution system, it's specifically designed for easy mounting and quick dismounting with the assurance of touch protection.

Features & Benefits

• Withstands inrush voltage rating of 4kV, so prevents large surges causing equipment failure

• Inspection window displays pole conductor contacting for easy status checks

• Comes with integrated input wiring, so is ready to install

• IP20 rating means it's finger-safe and protected against objects larger than 12mm

Applications

• Welding equipment

• Industrial lighting

• Factory automation

How do I mount this MCB?

You can easily mount this MCB directly onto a standard 35mm DIN rail without needing to use any tools.
