Miniature Circuit Breakers(MCBs) protect installations against overload and shortcircuit, warranting reliability and safety for operations. New System pro M compact S 200 series ABB Miniature Circuit Breaker satisfies most common requirements in terms of MCBs, allowing the usage of them for domestic, industrial and commercial applications. Three series S 200, S 200 M and S 200 P with three different breaking capacities up to 25 kA are available, in all characteristics (B, C, D, K and Z) and configurations (1P, 1P+N, 2P, 3P, 3P+N and 4P), in all the sizes up to 63 A. It is also available a version with the new integrated auxiliary contact on the bottom side which permits to save 50% space. All these ABB Miniature Circuit Breakers (MCBs) comply to IEC/EN 60898 and IEC/EN 60947-2 Standards. Thought to be advanced, Miniature Circuit Breakers (MCBs) range also offers all the "plus" advantages which characterized the whole new System pro M compact range. S 200 series devices obtained a lot of marks and approvals, so they can be used in all world's markets.

New ABB Controls System pro M compact range of auxiliary elements and accessories is universal: in fact it is suitable for Miniature Circuit Breakers (MCBs) S 200 range, for Residual Current Devices (RCDs) F 200 range, for RCD-blocks DDA 200 range and also for RCBOs DS 200 range and it is useful in terms of stock management. The auxiliary elements range (composed by auxiliary and signal contacts, shunt trips, undervoltage releases and automatic reclosing units) is quite wide and there are different possible schemes for assemblage with devices. All these configurations are possible without the need of any dedicated auxiliary interface contact.

Thus Miniature Circuit Breakers (MCBs) and Residual Current Devices (RCDs) performances are improved, even because innovative and integrated solutions can be used in every installation. The connection accessories range (busbars, connection terminals, feeder terminals) allows any kind of wiring. The range of standard accessories (labels, covers) permits to customize the installation. Thanks to the compatibility between the new System pro M compact range and the System pro M range ABB Low Voltage Controls offers many additional functionalities like: protection and switching, checking and monitoring, control and programming. Shape and dimensions of the new series ABB Miniature Circuit Breakers allow both precise adapting in already existing installations and continuity in terms of profile and appearance.

The MA series Altech Miniature Circuit Breaker was designed to handle the high inrush loads of 3 phase transformers, power supplies, motors, etc. The MA series Altech MCB protects wiring and equipment from damage caused by the three major classes of over-current, yet greatly reduces the number of nuisance trips in high starting and inrush current circuits. An IEC device with excellent ratings under a UL listing at 480Y/277V (including group ratings) and at 500V under international standards, the Altech Sursum MA Miniature Circuit Breaker provides short and long term cost effective circuit protection for USA and/or export applications.

The short term advantages include: (1) adjustable thermal trip allows finalization of initial designs before procurement of the load equipment is complete; (2) snap-on mounting for readily available, internationally standardized DIN Rail saves panel layout design time as well as installation and change labor; (3) large cage-clamp terminals with screws suitable to power screwdrivers, simplifies and speeds wiring; (4) convenient switched disconnect during factory testing and/or initial start-up saves time and aggravation. The key long term advantage is customer satisfaction and proven over-current protection of wiring and equipment (and the lack of rework/repair costs).

Miniature circuit breakers (MCBs) are used throughout the world in all types of electrical in stal la tions. ABB MCBs are recognized for use by Underwriters Laboratories Standard UL1077 for supplementary circuit protectors in systems rated 240VAC, 480VAC and 600VAC. Devices are certified per CSA C22.2. ABB Miniature Circuit Breakers (MCBs) are approved per IEC-898 and VDE 0641, and certified under IEC-947 and VDE 0660 standards for use in systems rated 415VAC or 690VAC (S500 series). Miniature Circuit Breakers (MCBs) can be applied to 16 2/3Hz to 400Hz and DC power systems. Special direct current version MCBs include a permanent magnet for DC fault current interruption.

These "UC" versions are rated 250/500VDC under UL1077/CSA 22.2 No. 235. Continuous current ratings are as low as 0.2 amperes and up to 125 amperes maximum. Miniature Circuit Breakers (MCBs) are of compact size and can be quickly mounted on standard 35mm Entrelec DIN Rail or can be front mounted by use of a front mounting kit. Miniature Circuit Breakers (MCBs) include line and load side terminals for conductors from 18 through 4AWG (0.75 to 25mm2) for 40 amperes; up to 2AWG for 50 and 63 amperes. ABB MCBs can also be connected via busbar conductors which can be either upper or lower mounted for top feed or bottom feed. Dual function terminals allow busbars to be connected with main incoming line conductors without separate lugs.
