ABB Circuit Breakers

ABB SACE Breakers - Tmax Molded Breakers - Mini-Breakers

Control Panel Fabrication Information

NEMA, UL & CSA Ratings

ABB offers a complete line of NEMA, UL & CSA miniature, molded case and power circuit breakers, residual current (ground fault) devices, manual motor starters to protect personnel and equipment. ABB circuit breakers offer the best solution for rapidly restoring normal electrical service after a fault and, at the same time, offering the maximum protection of the electrical installation. The MCCB's have an extensive group of interchangeable accessories from electronic trip devices to flange handles.

ABB  Tmax Molded Case Circuit Breakers, MCCB’s


The ABB Tmax line of circuit breakers, with arange up to 3000A, has several key features that go along with its very small size: 

  • Double insulation – this constructioncharacteristic allows for the UL Listed field installation of internal accessorieswithout exposure to energized parts.
  • Complete range of electrical and mechanical accessories
  • Positive operation – breakers from ABB ensure that the toggle indicates the precise position of the moving contacts.  This guarantees safe and reliable signaling by the device. 
  • Installation – Tmax molded case ABB circuit breakers 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.
  • Interrupting ratings at 480VAC up to 150kAIC.
  • Compact size
  • All Tmax molded case ABB circuit breakers are UL Listed and IEC rated for global application and acceptance.
  • All versions of the Tmax family aresuitable for reverse feed applications.

The ABB Tmax product line has the performance and accessories to satisfy all industry requirements in the 600VAC to 600VDC ranges.

ABB Emax Power Breakers

Air circuit breakers can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit breakers of electrical machines (generators, motors, transformers, capacitors).

These can be used both as circuit-breakers for general protection (of plants, of user complexes, of electric lines) and as protection circuit-breakers of electrical machines (generators, motors, transformers, capacitors). They are used in all types of plants (civil, industrial, and in the service sector) as well as in the equipment on-board ships, in mines, in prefabricated substations, and for primary and secondary distribution in general.

ABB SACE Breaker Specific characteristics
All the SACE Emax circuit-breakers except for Emax X1, have the same height and depth both in the fixed and withdrawable version and allow construction of compact switchgear.
They are fitted with many features which mean the personnel can always work under conditions of maximum safety, such as racking-out with the door closed, degree of protection towards the outside up to IP54, an articulated series of safety locks and double insulation.
The innovative structure of the pole guarantees complete insulation between phases and between phase and neutral and ensures full possibility of inspection of the arcing chamber and the main contacts.
SD Pocket is an innovative function which means a PC, even a hand-held one, can dialogue with Emax by means of the Bluetooth protocol. By means of the PC, and without any cables, the following is now possible, for example: the setting of the various protections, display of the measurements including those stored in the Data Logger, to verify the state of the circuit-breaker, know the number of operations carried out, etc..

ABB SACE Breaker Conformity with Standards
The SACE Emax circuit-breakers and their accessories are according to the international IEC 947, EN 60947 (harmonised in 28 countries of the CENELEC), CEI EN 60947 and IEC 1000 Standards and conform to the EC Directive:

  • "Low Voltage Directives" (LVD) no. 73/23 EEC
  • "Electromagnetic Compatibility Directive" (EMC) no. 89/336 EEC.

Furthermore, a series of SACE Emax circuit-breakers conforming to the UL 1066 Standards is available.
