Product Description
SB203M-C25 Miniature Circuit Breaker - 3P - C - 25 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.
Engineered for Robust ProtectionDesigned for use in all types of electrical distributions, the ABB SB203M-C25 MCB guards circuits against faults and overloads effectively. Its C type curve enables fast response to faults, avoiding equipment damage, and the mechanical life of 20,000 operations ensures durability in frequent switching environments.
Ease of Installation and UseThe ABB Triple Pole MCB features standard DIN rail mounting for quick, reliable installation in panels. Its compact dimensions and user-friendly terminal capacity (1-25 mm2) simplify wiring. The clear red/green window provides instant status updates, promoting safer operation.
Trusted Compliance and Safety StandardsCompliant with IEC/EN 60898-1 and RoHS certified, the SB203M-C25 is manufactured with high-grade, flame-retardant materials. This guarantees not only reliable circuit protection but also adherence to environmental and quality regulations.
FAQ's of ABB Triple Pole MCB /SB203M-C25:
Q: How does the C type curve tripping characteristic benefit residential and industrial applications?
A: The C type curve on the ABB SB203M-C25 MCB means it trips instantly when fault currents reach 5 to 10 times the rated current, offering fast protection against short circuits and moderate resistance to nuisance tripping, making it ideal for mixed loads found in residential, commercial, and industrial systems.
Q: What is the maximum breaking capacity of this MCB and why is it important?
A: This MCB features a 6000A breaking capacity, indicating it can safely interrupt fault currents up to this level without damage. This high rating enhances safety by ensuring reliable disconnection during severe electrical faults.
Q: When should the ABB SB203M-C25 MCB be used in a distribution system?
A: You should use this MCB whenever protecting electrical circuits against overload and short circuit currents is required, especially in three-phase distribution boards for homes, buildings, or industrial facilities operating up to 415V AC.
Q: Where can I install the ABB Triple Pole MCB?
A: The MCB is designed for use in standard 3-pole DIN rail mount panels within residential complexes, commercial buildings, or industrial premises, as well as any environment requiring IP20-level protection and robust electrical safety measures.
Q: What is the process for checking the operational status of this MCB?
A: You can instantly verify the on/off state by observing the integrated red/green contact position indicator window on the front of the device, improving maintenance efficiency and safety during system checks.
Q: How does the high-grade thermoset plastic housing enhance the safety of this MCB?
A: The use of flame-retardant thermoset plastic minimizes fire risks associated with electrical faults, ensuring higher resilience against heat and adding an essential layer of protection in critical installations.
Q: What are the benefits of RoHS compliance for this MCB?
A: RoHS compliance ensures that the MCB is free from hazardous substances, supporting both environmental sustainability and safer operation, which is particularly critical in modern electrical installations.
