The ABB S201-C20 (article 2CDS251001R0204) is a single-pole 20 A miniature circuit breaker from ABB's S200 series, rated for a breaking capacity of 6 kA at AC voltage with a C trip characteristic. It operates through two independent tripping mechanisms - a delayed thermal element that responds to sustained overloads and an electromechanical element that reacts to short-circuit currents. As a current-limiting device, it is approved for use in residential, commercial, and industrial low-voltage installations.

Technical specifications:

• Series: S201-C20
• ABB article number: 2CDS251001R0204
• EAN: 4016779464505
• Type: Miniature Circuit Breaker (MCB)
• Pole configuration: 1P (single-pole)
• Rated current: 20 A
• Trip characteristic: C
• Breaking capacity: 6 kA at 230/400 V AC

Features and benefits:

• Current-limiting design reduces the energy let through during a fault, limiting stress on downstream wiring and equipment
• C trip characteristic handles moderate inrush currents, making it appropriate for general lighting and power distribution circuits
• Separate thermal and electromechanical trip elements give independent protection against overload and short-circuit faults respectively
• Bottom-fitting auxiliary contact accessory can be added without occupying extra rail width, saving up to 50% of the space a conventional side-mounted contact would require
• Compliant with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, permitting use across residential, commercial, and industrial applications

Applications:

• Branch circuit protection in residential consumer units and distribution boards
• Commercial building sub-distribution panels and final circuits
• Industrial control cabinets and machine protection circuits
• General-purpose lighting and socket-outlet circuit protection
