CHINT NXB-63 1P–4P Miniature Circuit Breaker, 1–63 A
The CHINT NXB-63 protects AC circuits against overload and short-circuit faults. This listing offers 1P, 2P, 3P, 4P configurations. Match the rated current to the conductor and load, then confirm the tripping characteristic and fault-level requirement for the installation.
NXB-63H (10 kA), NXB-63G and DC circuit breakers are separate versions. For an inverter installation, this NXB-63 listing concerns the AC side; do not use it as a PV DC breaker.
