Umehluko phakathi kwe-breaker circuit breaker 1P+N ne-2P

I-1P+N yokuvuza i-circuit breaker ithi:

I-Monopole two wire, okungukuthi, ucezu olulodwa lokushintshwa komoya, kanye nemojula yokuvikela ukuvuza ehlanganiswe ne-switch, ulayini womlilo, umugqa onguziro ndawonye ngaphakathi nangaphandle kwe-switch yenhlanganisela, lapho ukuvuza kwenzeka lapho imojula yokuvuza ishayela umoya. shintsha uhambo, ulayini womlilo kuphela kanye nenethiwekhi yangaphandle enqanyuliwe, futhi ulayini onguziro uhlala uvulekile.

I-2P yokuvuza i-circuit breaker yile:

Okubili - isivikeli sokuvuza kwezintambo, isishintshi somoya esiyizingcezu ezi-2 kanye nemojula yokuvuza.Lapho ukuvuza kwenzeka, imojula yokuvuza ishayela ukushintshwa komoya ukuhamba!Ulayini womlilo, ulayini onguziro kanye nogesi wenethiwekhi yangaphandle konke kunqanyuliwe.Kuphephe kakhudlwana!
