CQB2LE-125 Selection Summary<\/h2>\n

The CQB2LE-125 RCBO covers 63A \/ 80A \/ 100A \/ 125A, 1P+N \/ 2P \/ 3P \/ 3P+N \/ 4P and C \/ D trip curves. Published short-circuit data is 10kA or 6kA lower type (Icu). Residual-current options are 30 \/ 50 \/ 75 \/ 100 \/ 300mA (Electronic type; waveform type is not stated in the saved technical table). Confirm every option against the conductor, load, fault level, supply system and applicable rules.<\/p>\n

Ph\u1ea7n CQB2LE-125 RCBO<\/strong> provides overload, short-circuit and residual-current protection within its published 63A \/ 80A \/ 100A \/ 125A range. Selection should be based on the circuit voltage, conductor, load behaviour, prospective fault current and applicable installation rules\u2014not the ampere rating alone.<\/p>\n
