LV Circuit Breaker
Eurelecs proposes a wide range of low voltage circuit breakers. All circuit breakers are manufactured according to IEC 947-2 Under KEMA , VDE and BSI Certificates.
We offer Low Voltage Air Circuit Breakers (ACB) from 400A to 2500 A – 3 and 4 Pole with Breaking capacities from 55 to 60 KA in fixed & withdrawable types under the license of UNELEC Spectronic & U-Pact (France). Designed to match the most demanding requirements
for rapid detection and safe interruption of faults, our Spectronic ACB and associated RV protection relay incorporate a formidable array of circuit protection and system management. Withdrawable type breakers incorporate rotary handle mechanism that can be manually or electrically charged via a motor mechanism. Each unit is contained within a ‘cassette’ for simple insertion or removal from the switchboard.
