The right RCCB for every application
| Merlin Gerin, a brand of Schneider Electric, is now offering one of the UK’s most comprehensive families of RCCBs (residual current circuit breakers). This includes innovative products for special applications, such as those involving unattended equipment or corrosive atmospheres, as well competitively priced standard products for everyday applications in shops, offices and residential premises.
The latest addition to the Merlin Gerin RCCB family is the RED range of devices which monitor the effects of a transient earth fault and automatically restore the supply when the fault has cleared. RED RCCBs offer a unique and convenient option for protecting installations in unstaffed locations, such as pumping stations and telecommunications relay stations, while minimising unnecessary downtime.
For use where there is a risk of RCCB tripping due to successive lightning strikes, but supply interruptions must be kept to a minimum, Merlin Gerin offers type Si devices. These are complemented by type SiE RCCBs which are fully sealed and are, therefore, suitable for use in corrosive atmospheres such as those encountered in sewage processing installations, chemical plant and even marinas.
Domestic and standard commercial applications are catered for by AC class MCCB products from Merlin Gerin, while A class products provide dependable protection for installations where large numbers of individual items of electronic equipment may be in use at the same time. Typical examples include school computer rooms, Internet cafés and telephone exchanges.
Since variable speed drives can give rise to problems for standard RCCBs, Merlin Gerin offers B class devices that are specially optimised for applications of this type. They are also suitable for use with forklift truck battery chargers and in other applications where the load is likely to produce a pure DC component in the supply.
Further details of all of the Merlin Gerin RCCBs now available from Schneider Electric are given in the new RCCB Family Offer brochure. This is available for download from the Schneider Electric website, or it can be requested in hard copy form from the Schneider Electric customer information centre on 0870 608 8 608.
