Overview

The MidNite Solar MNEPV 150VDC circuit breaker provides compact DC overcurrent protection for photovoltaic, battery, telecom, UPS, and other DC power systems. This single-pole breaker uses hydraulic-magnetic trip technology, mounts on DIN rail, and is non-polarized for reverse-feed operation. Its compact 13 mm module width helps conserve enclosure space while providing manual switching and electrical isolation capability.

Key Features

  • 150 VDC rating: Designed for DC circuit protection at up to 150 VDC per pole.
  • Non-polarized design: Reverse-feedable for flexible DC system installation.
  • Hydraulic-magnetic operation: Provides 100% rating capability independent of ambient temperature.
