- UL Listed for Safety – Independently tested and certified for high-voltage DC protection.
- Dual-Pole Design – Internally ganged to ensure simultaneous tripping of both poles.
- Designed for MidNite Solar Combiners – Compatible with MNPV12-250, MNPV16-250, and other high-voltage breaker panels.
- Prevents Arc Faults & Overcurrent Damage – Protects systems from dangerous electrical faults.
Applications
- Solar PV systems with high-voltage configurations
- Battery-based energy storage protection
- DC distribution panels in off-grid and grid-tied systems
- Commercial and industrial renewable energy installations
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.
