ABB SB203M-C50 Circuit Breaker: FAQs
What is the primary function of the ABB SB203M-C50 miniature circuit breaker?
The ABB SB203M-C50 is a 3-pole miniature circuit breaker (MCB) designed for dependable circuit protection in industrial and commercial settings. Its main function is to protect electrical circuits against overloads and short circuits, thereby preventing damage to equipment and reducing the risk of electrical hazards.
What are the key electrical specifications of the ABB SB203M-C50?
This MCB has a rated current of 50 Amps and is designed for a rated voltage of 415V AC at a frequency of 50 Hz. It features a C-curve tripping characteristic, making it suitable for circuits with moderate inrush currents. The ultimate breaking capacity (Icu) is 10kA, and the rated short-circuit capacity (Ics) is 7.5kA.
What does the “C-curve tripping characteristic” signify in this MCB?
A C-curve tripping characteristic indicates that the circuit breaker will tolerate a moderate level of short-term overload, typically 5 to 10 times the rated current, before tripping. This makes it suitable for applications with moderate inrush currents, such as small motors and lighting circuits with inductive components, which can experience a temporary surge of current when initially switched on.
What type of protection mechanisms does the ABB SB203M-C50 employ?
The SB203M-C50 utilizes dual tripping mechanisms to ensure comprehensive protection. It features a thermal tripping mechanism, which provides delayed protection against sustained overloads, and an electromechanical tripping mechanism, which offers instantaneous protection against short circuits.
For what kind of applications is the ABB SB203M-C50 typically used?
This miniature circuit breaker is commonly used in electrical control panels, motor starter panels, commercial electrical installations, industrial automation systems, HVAC systems and pump panels, machinery and equipment power protection, as well as solar and power distribution boards. Its compact size and reliable performance make it suitable for a wide range of industrial and commercial applications.
Is the ABB SB203M-C50 compliant with any specific industry standards?
Yes, the ABB SB203M-C50 is compliant with the IS/IEC 60898-1 standard. This compliance ensures that the product meets recognized international safety and performance requirements for low-voltage circuit breakers for household and similar installations.
What are some of the benefits highlighted for industrial buyers choosing this MCB?
Industrial buyers often prefer the ABB SB203M-C50 for its consistent performance, easy mounting, and space-saving profile. It is designed to meet safety norms and handle high-load scenarios effectively. Furthermore, being part of ABB’s System pro M Compact SB200M series and available through verified vendors on Industrial Products India ensures quality and reliable support.
