Product Description
SB202M-C63 Miniature Circuit Breaker - 2P - C - 63 A
System pro M compact SB200M Miniature Circuit Breakers are current limiting. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in different characteristics (B,C,D), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 10 kA at 240/415 V AC) and rated currents (up to 63A). All MCBs of the product range SB200M comply with IS/IEC 60898-1, allowing the use for residential, commercial and industrial applications.

Its 10kA breaking capacity and dual-pole design make it an ideal choice for managing high-current loads reliably in demanding environments, providing dependable defense against electrical faults.
User-Friendly FeaturesThis MCB includes a contact position indicator, facilitating swift status checks and maintenance. Its DIN rail mounting system ensures fast installation, while the compact size allows for easy integration within new or existing panels. The flame retardant housing further enhances user and installation safety.
FAQ's of ABB Double Pole MCB /SB202M-C63:
Q: How does the C curve tripping mechanism of the ABB SB202M-C63 MCB function?
A: The C curve tripping mechanism is specifically designed to protect circuits with moderate surge currents, such as those caused by motor starters or fluorescent devices. It instantly trips when the current reaches 5 to 10 times its rated current, ensuring quick disconnection during short circuits without nuisance tripping during normal operational surges.
Q: What applications is the ABB Double Pole MCB suitable for?
A: This MCB is ideal for residential, commercial, and industrial applications. Its 63A rated current and robust design make it suitable for protecting lighting, power outlets, and machinery circuits where double phase protection is required.
Q: Where can this MCB be installed, and what mounting options are available?
A: The ABB SB202M-C63 is designed for DIN rail mounting, making it compatible with standard distribution boards and panels commonly found in homes, offices, factories, or other commercial/industrial settings.
Q: What is the maximum cable size supported by the terminal connections?
A: The terminal capacity supports cables up to 25mm2, accommodating a wide range of wiring needs in various installation scenarios.
Q: How can users benefit from the contact position indicator included with the MCB?
A: The contact position indicator shows the real-time status of the circuit breaker, allowing users to verify easily whether the device is ON or OFF, which improves safety during maintenance and troubleshooting.
Q: What are the durability features of this MCB in terms of operational life?
A: The device provides an approximate mechanical life of 20,000 operations and an electrical life of about 10,000 operations, ensuring reliability and longevity even with frequent usage.
