EATON - MCB RCCB RCBO and DIN Rail Isolators

  • Eaton’s range of 6kA high performance Miniature Circuit Breakers (MCBs) are manufactured to IEC/EN 60898, meeting the latest UK, European and International standards, with ratings from 2A to 63A as standard.
  • DIN rail mountable and suitable for use with both pin and comb type busbar systems
  • Eaton’s MCBs are suitable for use on 230/240 V, AC systems and are calibrated for use at 40°C.
  • These devices suite with the other modular devices including RCBOs, RCCBs and Isolators, for use within Eaton’s consumer units and a wide range of other applications. 
  • The Eaton 6kA MCBs are fitted with box clamp terminals suitable for use with cables up to 25mm2.
  • Available with both B and C characteristic curves as standard. Type B MCBs are most commonly used in domestic applications, however the use of type C devices may be desirable e.g. on lighting circuits where high switching surges are involved. Type D devices are not commonly used in other than industrial applications.

Technical Details

  • Type B: Suitable for general, domestic and commercial installations having little or no switching surges
  • Type C: Suitable for general use in commercial or industrial applications where the greater use of fluorescent lighting and small motors can produce switching surges, which may cause nuisance tripping of type B breakers.
  • Type D: Suitable for General Industrial applications where there are a lot of high inrush switching surges associated with equipment such as transformers, large motors, welding and X ray equipment.
