Product Description
SB204M-C1 Miniature Circuit Breaker - 4P - C - 1 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.
Durability and EnduranceEngineered to withstand frequent use, the ABB SB204M-C1 offers an impressive mechanical endurance of up to 20,000 operations and electrical endurance for 10,000 cycles. The device ensures long-term reliability in demanding environments, maintaining performance across a wide operating temperature range from -25C to +55C.
Installation FlexibilityThe MCB is designed for quick and secure DIN rail mounting, with a terminal capacity supporting conductors up to 10 mm2. Its modular four-pole structure makes it easy to integrate into standard panels, while the IP20 protection rating and flame-retardant thermoplastic enhance safety in all settings.
Standards ComplianceThis model fully complies with IEC/EN 60898-1 standards, ensuring trusted performance and adherence to global safety norms. It suits both new installations and replacement projects for residential, commercial, or industrial electrical distribution.
FAQ's of ABB Four Pole MCB /SB204M-C1:
Q: How is the ABB SB204M-C1 Four Pole MCB installed in an electrical panel?
A: The ABB SB204M-C1 is designed for DIN rail mounting, making installation straightforward. Simply snap the breaker onto a standard DIN rail in your distribution board and connect conductors up to 10 mm2 to the terminals. Ensure the panel is de-energized before installation for safety.
Q: What applications are suitable for the ABB SB204M-C1 MCB?
A: This four-pole MCB is ideal for use in residential, commercial, and industrial installations requiring protection against overload and short circuit faults. Its design supports three-phase plus neutral circuits commonly found in larger distribution setups.
Q: When should I consider using a C Curve tripping characteristic?
A: A C Curve MCB like the SB204M-C1 is suitable for circuits with moderate inrush currents, such as those with motors or fluorescent lighting. It provides reliable protection by allowing brief surges without nuisance tripping while reacting quickly to genuine fault conditions.
Q: Where can the ABB SB204M-C1 MCB be sourced in India?
A: This model is available through authorized dealers, distributors, exporters, retailers, suppliers, traders, and wholesalers across India. You can approach any official ABB channel partner for purchase and support.
Q: What benefits does the high-grade thermoplastic enclosure offer?
A: The MCB's enclosure is made from flame-retardant, high-strength thermoplastic, ensuring enhanced fire safety and durability. This material choice contributes to the device's robust IP20 protection, guarding users from accidental contact with live parts.
Q: How does the SB204M-C1 ensure reliable operation in different conditions?
A: The breaker operates effectively within a wide temperature range of -25C to +55C, and its mechanical and electrical endurance ratings (20,000 and 10,000 cycles respectively) assure consistent performance even in high-usage scenarios.
