CNC YCB9N-40 1P+N MCB — 10A to 40A<\/h2>\n

The 1P+N MCB switches both live and neutral in a single-module width (18mm). It provides the same protection as a standard single-pole MCB but also disconnects the neutral on trip — an important safety feature for Pakistani wiring where phase and neutral can sometimes be reversed at the meter.<\/p>\n

Because it takes only one DIN-rail module instead of two, you can fit twice as many circuits into the same DB box. This makes it the go-to choice for apartment and house panel boards where space is tight.<\/p>\n

    Why 1P+N Over Standard 1P?<\/h2>\n

    In Pakistan, meter wiring and internal house wiring sometimes swaps phase and neutral. A standard 1P MCB only breaks the line conductor — if the neutral is accidentally on the line terminal, the circuit stays live even after the MCB trips. The 1P+N design disconnects both conductors, eliminating this risk. It costs slightly more than a plain 1P MCB but the safety margin is worth it for residential use.<\/p>\n","protected":false},"excerpt":{"rendered":"
