A: for miniature circuit breakers, 1p + N and 2p are generally controlled by two lines, but the effect is different.1p + n ---- single pole + n circuit breaker, which controls live line and zero line ···
Answer: P refers to modulus, and a p modulus is 18mm; 1p ----- single pole circuit breaker with thermal magnetic tripping function, which only controls the live line (phase line);This is the 1p circui···
