ABB S200 is a modular miniature circuit breaker family for overload and short-circuit protection in final-circuit distribution. The supplied product content covers S200, S200M and S200P segments with breaking capacities of 6 kA, 10 kA and 25 kA.
The ABB S200 Series Miniature Circuit Breakers (MCBs) are designed to provide reliable overload and short-circuit protection for low-voltage electrical distribution systems. Featuring a compact DIN-rail-mounted design, thermal-magnetic tripping technology and multiple current ratings, the series offers flexible protection solutions for residential, commercial and industrial installations. With different tripping characteristics, pole configurations and breaking capacity options, S200 circuit breakers can be selected to match various electrical load requirements. Their contact position indication, finger-safe terminals and compatibility with ABB System pro M compact® accessories further support convenient installation, operation and maintenance.
The S200 series uses thermal-magnetic tripping technology to protect electrical circuits against sustained overloads and short-circuit faults. Available B, C, D, K and Z tripping characteristics accommodate different load conditions, allowing users to select appropriate protection for lighting circuits, general electrical distribution, motors, transformers and sensitive electronic equipment. Its current-limiting design helps reduce the energy released during short-circuit events, supporting improved protection of downstream equipment and electrical installations.
The ABB S200 product range includes different versions to accommodate varying short-circuit protection requirements:
S200: Standard miniature circuit breakers for general electrical distribution applications.
S200M: Higher breaking capacity versions for installations with increased short-circuit requirements.
S200P: High-performance versions for applications requiring enhanced breaking capacity.
S200 M UC: Dedicated AC and DC circuit protection versions for selected industrial applications.
Available configurations include 1P, 2P, 3P and 4P, with additional 1P+N and 3P+N options depending on the product reference. These variations provide flexibility for single-phase and three-phase distribution systems.
Designed for modular electrical distribution boards, the S200 series supports standard 35 mm DIN-rail mounting. Its twin-terminal arrangement allows busbars and conductors to be connected separately, simplifying wiring and distribution board assembly. IP20 finger-safe terminals help reduce accidental contact with live parts during installation, while captive screws provide secure terminal connections.
The Contact Position Indication (CPI) system uses a green/red indicator to show the actual position of the main contacts independently of the operating toggle position. Laser-marked product identification and certification information also improve model recognition during installation, inspection and replacement.
The S200 series is fully compatible with a wide range of ABB System pro M compact® accessories. Depending on the selected model, available accessories include auxiliary contacts, signal contacts, shunt trip releases, undervoltage releases and other modular control devices. These components allow circuit breakers to be integrated into electrical control, remote indication and monitoring arrangements.
The series can also be combined with compatible ABB modular distribution products to create coordinated electrical protection and control assemblies.
The ABB S200 Series MCBs are suitable for branch circuit protection and electrical distribution in various installation environments. Typical applications include:
Residential Buildings: Protection for lighting circuits, socket outlets and household distribution circuits.
Commercial Facilities: Circuit protection in offices, retail buildings, hotels and commercial distribution panels.
Industrial Control Panels: Protection for auxiliary circuits, control systems and industrial electrical equipment.
Motor and Transformer Circuits: Suitable tripping characteristics for selected motor and transformer protection applications.
Electronic Equipment: Z-curve versions for selected sensitive electronic and semiconductor-related circuits.
Electrical Distribution Systems: Overcurrent protection for modular distribution boards and low-voltage installations.
The ABB S200 series offers multiple electrical ratings and configurations to meet different circuit protection requirements.
Rated Current: Common standard versions cover approximately 0.5–63 A, with specific subseries offering different ranges.
Pole Configuration: 1P, 2P, 3P and 4P, with 1P+N and 3P+N options depending on model.
Tripping Characteristics: B, C, D, K and Z curves, depending on the selected version.
Breaking Capacity: Different levels are available across S200, S200M and S200P versions.
Tripping Technology: Thermal-magnetic protection.
Installation: Standard 35 mm DIN-rail mounting.
Terminal Design: Twin terminals for separate busbar and conductor connections.
Protection Features: Current-limiting design, IP20 finger-safe terminals and Contact Position Indication.
Standards: IEC/EN 60898-1 and IEC/EN 60947-2 for applicable versions; additional UL and CSA approvals are available for selected product variants.
Accessories: Compatible ABB System pro M compact® auxiliary contacts, signal contacts and control accessories.
