Installation
This MNEPV40-300-1PP circuit breaker is designed for seamless integration into MidNite Solar’s MNPV12-250 and MNPV16-250 combiners. It must be installed following NEC and local electrical codes. The dual-pole internal configuration ensures that both poles trip together for maximum system protection.
Advanced High-Voltage Protection
Unlike standard DC breakers, this unit is engineered for 300VDC operation with robust arc-quenching technology to prevent high-voltage arcing. It is not safe to replace with two externally linked 150VDC breakers, as that setup cannot withstand high-voltage surges.
