ABB MCB, 6kA Breaking Capacity, IP20 Rating - S200 Series - 2CDS251001R0105 - S201B10 Use this single-pole MCB from ABB to protect people and equipment from the harmful effects of overvoltage. The type-B unit trips instantly to break a single-phase circuit whenever the current supplied exceeds 3 to 5 times its rated current of 10A. As its sensitivity helps ensure prompt breaking whenever the slightest overcurrent occurs, this is a safe choice for use in residential settings where surges are small. Because MCBs work like switches, you simply reset this unit manually after a fault so it can continue to protect your circuit and connected devices. Features & Benefits • Current limiting, so it restricts how much harmful current can pass through during a fault for user safety
• Mounts without tools to a 35mm DIN rail for quick and easy installation
• IP20 rating means it’s protected from objects greater than 12mm, including fingers
• Resistant to shock and vibration for durability in demanding environments Applications • Light commercial spaces
• Domestic distribution panels
• Factories How do MCBs work? MCBs use an internal strip made of two types of metal. The metals bend at different temperatures when heated by overcurrent, which deforms the strip and triggers a latch. This breaks the circuit to ensure safety for equipment and users.
