Small leakage circuit breaker 63A 1P+N

Product Introduction

• In the face of the increasing demand for high-power single-phase electricity in modern residential, commercial and other environments, traditional circuit protection schemes often require the occupation of two modules of space (1P circuit breaker + leakage accessory or 2P leakage circuit breaker), which can easily cause layout difficulties in the distribution box.
• The Small leakage circuit breaker 63A 1P+N innovatively integrates overload, short-circuit and high-sensitivity leakage protection functions within a width of only one standard module (18mm), and can simultaneously break the phase line (L) and the neutral line (N). It can provide complete safety protection for single-phase high-current circuits.

Q&A

Q:What are the differences in protection between 1P+N and 2P leakage circuit breakers?

A:It is completely equivalent in the overload, short circuit and leakage protection functions at the core of the circuit. The main difference lies in the physical structure: 1P+N adopts a single-mode compact design, while 2P has a dual-mode width. Both can simultaneously disconnect the L line and the N line.

Q:How is the neutral line (N) protected in this model?

A:The N-pole of this type of Small leakage circuit breaker 63A 1P+N, only switches on and off synchronously with the phase line, providing isolation function. However, it usually does not have an independent overload protection magnetic trip (i.e., N-pole overload does not cause tripping alone). Its feature is to provide complete leakage protection and safe bipolar isolation.
