Product Description
SB203M-C2 Miniature Circuit Breaker - 3P - C - 2 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.
Precision Protection for Critical CircuitsFeaturing a 6kA breaking capacity and a C Curve tripping characteristic, the ABB SB203M-C2 offers finely tuned protection against overloads and short circuits. Its rapid response and consistent operation safeguard both equipment and people, making it perfect for sensitive installations in industrial, commercial, or residential settings.
Built for Versatility and ReliabilityConstructed from flame retardant thermoplastic, the device is designed for durability and safety. It supports a wide wire size range and integrates seamlessly onto standard DIN rails, ensuring quick and reliable mounting for any electrical distribution board. The wide operating temperature tolerance provides consistent performance in diverse climates.
User-Friendly DesignInstallation and maintenance are straightforward, thanks to the screw clamp terminals and modular shape. With clearly labeled connections and an IP20 protection level, the SB203M-C2 makes system upgrades and troubleshooting easier, enhancing the convenience and dependability dealers and installers require.
FAQ's of ABB Triple Pole MCB /SB203M-C2:
Q: How do I install the ABB Triple Pole MCB SB203M-C2 on a distribution board?
A: The SB203M-C2 is designed for standard DIN rail mounting. Simply fix the MCB onto the 35mm DIN rail, then connect the wires (1-25 mm2) to the screw clamp terminals, ensuring all connections are secure before turning on the power.
Q: What applications benefit the most from using the SB203M-C2 MCB?
A: This MCB is ideal for three-phase applications in residential, commercial, and light industrial settings, protecting circuits from short-circuits and overloads. Its robust build and electrical characteristics suit environments with a high demand for safety and efficiency.
Q: When should the SB203M-C2 MCB be replaced?
A: While the SB203M-C2 offers a mechanical life of 20,000 operations and an electrical life of 10,000 operations, it should be replaced if you notice tripping issues, visible damage, or after the maximum operation limits are approached to ensure safety and compliance.
Q: Where can I purchase the ABB SB203M-C2 in India?
A: You can buy the ABB SB203M-C2 from certified dealers, distributors, exporters, retailers, suppliers, traders, and wholesalers across India. Ensure you purchase from authorized sources to guarantee product authenticity and after-sales support.
Q: What are the advantages of the C Curve tripping characteristic in this MCB?
A: The C Curve tripping characteristic allows the MCB to tolerate short-duration inrush currents, which is common with inductive or motor loads, while still providing effective protection against sustained overloads and short-circuit conditions.
Q: How does the flame retardant thermoplastic housing enhance safety?
A: The flame retardant thermoplastic housing mitigates the risk of fire, offering an added layer of protection for installations prone to electrical faults or overheating. This ensures compliance with modern safety standards and enhances user confidence.
