The S2 Series of ABB miniature circuit breakers offer a compact solution to protection requirements. The S2 devices are current limiting, DIN rail mounted and can offer a good equivalent to fused systems. The S2 is available with application-specific trip characteristics to provide maximum circuit protection. The breakers offer thermal-magnetic trip protection according to B, C, D, K and Z characteristics. For the worldwide market, ABB breakers carry UL, CSA, IEC, CE and many other agency approvals and certifi cations.

• Current limiting
• Fast breaking time (2.5 - 3.5 msec)
• Unique bus connection system
• Finger safe, Multi-Function terminals

The ABB Tmax breaker has been developed to complement the performance-proven Isomax line of Circuit Breakers. This new breaker, with a range up to 600A, has several very big features that go along with its very small size.

• Double insulation
• Positive operation
• Tmax Series can be installed in panels and switchboards in either the horizontal or vertical planes while being fed from either end without any derating of their performance characteristics.
• Two ranges of accessories
• Interrupt ratings at 480VAC up to 150kAIC.
• UL Listed and IEC rated for global application and acceptance.

ABB RCDs provide Ground Fault equipment protection by monitoring the leakage of current to ground. The F200 and F670 series will trip when ground faults are detected in excess of the GF trip rating of the device. These devices provide GF protection only and are used in series with standard MCBs which provide overload and short circuit protection. The F200 and F670 series can be used as a main device providing GF protection for several MCB branch devices.

• The F200 and F670 series are UL1053 recognized for use in 480Y/277VAC applications.
• The F202 and F672 is for use in single phase/two wire or two wire systems. The F204 and F674 is for use in three phase/four wire systems.
• The F200 and F670 series RCDs replace the F360, F370 and F660 series with no change in fit, form or function.
• The F200 and F670 have a profile similar to the S2 MCBs and can be used with the MCB busbars.

The S3 ABB Isomax breaker family ranges from 15 through 225 amperes. The S3 trip mechanisms are non-interchangeable and use sensitive electromagnetic relays for overcurrent trip protection. Heat sensitive bimetals are used for Thermal Overcurrent Protection. Short circuit current protection begins at 10 times the thermal rating of the breaker and uses a magnetic coil principle. To meet all application needs, the S3 is available in various versions:

• T = Thermal-magnetic
• Q = 100% UL rated
• D = Molded case switch
• M = Magnetic only (MCP)
• G = 3X Mag (100 - 225A 3-pole only)

ABB High Performance MCBs of the S800S series limit energy and power in the event of a short-circuit cut-off. The specially developed double arc chamber system ensures these outstanding operating properties. Other outstanding properties of the S800S are:

• Convincing: selectivity to upstream overcurrent protection equipment due to a total cut-off time of just < 2.5 ms.
• Safe: Outstanding back-up protection thanks to the feature of limiting energy to a value of < 100 000 A2s (125A/50kA).
• Loading Capabilities: up to 125A rated current
• Tested: 50kA rated ultimate short-circuit breaking capacity
• Optional: characteristics B, C, D, K, KM, UCB, UCK (UL489 series currently being prepared).
• Compact: the tiniest of dimensions.
• Flexible: accessories are fitted by the customer.
• Optimum: the new S800S is the perfect supplement to the existing ABB low-voltage range.

ABB's Emax series of low voltage power circuit breakers embodies over half a century's experience and technological development in power circuit breakers. The Emax offers a series of breakers that is totally innovative in its technological design, ease of installation and use, making it the ideal solution for the growing requirements of designers, switchboard and switchgear manufacturers, installers, OEMs and users. The Emax power circuit breakers are UL Listed and meet the ANSI Standard for low voltage power circuit breakers. ABB Emax power circuit breakers are available in five different models (four sizes) with rated continuous current from 800A to 5000A and rated short-circuit current range from 42kA to 125kA (480V).

The S500 heavy-duty ABB circuit breaker fulfills these requirements by virtue of its technical features. It is equipped with a thermal and/or electromagnetic release to protect circuits, motors, switchgear and systems from the effects of overload and short-circuit currents.

• High breaking capacity
• Energy-limiting, Current-limiting
• Optimal selectivity
• Various versions for special applications
• Compact dimensions, DIN cap size

ABB galaxie circuit breakers are door mounted for AC and DC applications. The breakers offer thermal-magnetic and magnetic-only trip protection.
