WEG NRBE 100 A 4-Pole 300 mA RCCB Main Incoming Protection
The WEG NRBE 100 A 4-Pole 300 mA is a high-current industrial RCCB for main incoming earth fault protection on three-phase distribution boards and sub-main distribution boards in Saudi industrial, commercial, and infrastructure facilities. At 100 A and 300 mA sensitivity, this device provides fire-protection level earth fault detection at the incomer of sub-main distribution boards feeding multiple final circuits protected by smaller 30 mA downstream devices, creating the selective two-level protection scheme recommended by IEC 60364-5-53 and Saudi electrical installation standards.
High-Current Main Incomer Application
The 100 A rating suits sub-main distribution boards fed by 95–120 mm² cables from main switchboards, feeding 8–16 way distribution boards in medium-sized Saudi industrial buildings, office towers, hospital wings, and hotel floors. The 300 mA sensitivity at this level provides selectivity with 30 mA final circuit RCCBs: an earth fault on a final circuit trips only the 30 mA RCCB on that circuit; the 100 A 300 mA device remains closed, maintaining supply to all other circuits on the same board. This selectivity is critical in Saudi hospital and industrial facilities where loss of entire distribution board supply is unacceptable.
Saudi Building and Industrial Applications
Saudi Aramco residential camp distribution boards, SABIC industrial office building distribution, hospital wing sub-main distribution in Ministry of Health facilities, and airport terminal sub-main distribution boards all use 100 A 4-pole 300 mA RCCBs at the board incomer. Saudi MEP consultants specify NRBE series for these applications. Razz Middle East supplies 100 A 4-pole RCCBs for Saudi projects including design assistance for two-level protection selectivity schemes and technical submittals to project consultants.
