Product Description
SB204M-C63 Miniature Circuit Breaker - 4P - 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.

Durable and Easy to InstallConstructed from high-grade flame retardant thermoplastic, the MCB assures long service life with 20,000 mechanical and 10,000 electrical operations. Its DIN rail mounting design speeds up installation, making it user-friendly for dealers, distributors, and electricians alike.
FAQ's of ABB fOUR Pole MCB /SB204M-C63:
Q: How does the SB204M-C63 ensure safety in electrical distribution systems?
A: The SB204M-C63 provides instantaneous tripping under overload or short-circuit conditions, supported by a C-curve tripping mechanism and a high breaking capacity of 10 kA. This helps protect equipment and wiring from damage, minimizing downtime and hazards.
Q: What are the main applications of this four-pole MCB?
A: This ABB MCB is ideal for industrial and commercial electrical distribution, such as panel boards and sub-distribution systems in factories, malls, and offices. Its robust design supports safe management of three-phase circuits with high current demands.
Q: When should I consider using a four-pole MCB instead of a single-pole or double-pole type?
A: A four-pole MCB like the SB204M-C63 is recommended when protecting three-phase circuits, especially when there's a neutral conductor involved. This ensures complete isolation and safety for all phases and the neutral during electrical faults.
Q: Where is the SB204M-C63 typically installed?
A: This MCB is mounted on standard DIN rails within distribution boards or switchgear in commercial and industrial buildings. Its compact modular size ensures compatibility and ease of installation in various electrical panels.
Q: What is the process for installing this MCB?
A: Installation involves mounting the MCB onto a DIN rail, connecting input and output cables (up to 25 mm2), and ensuring all wiring follows safety standards. Its design also includes a contact position indicator to provide visual confirmation of breaker status.
Q: How does the contact position indicator benefit users?
A: The contact position indicator clearly displays the status of the breaker (ON or OFF), enhancing operational safety and making maintenance or troubleshooting more straightforward for users and technicians.
