MidNite Solar Surge Protection Device 300VAC

The MidNite Solar Surge Protection Device (MNSPD-300-AC) is a Type 1 surge protector designed to shield solar and electrical systems from voltage transients and lightning-induced surges. Rated at 300VAC with an 80kA surge current per phase and a 1200V line-to-ground VPR, it suits combiner box and disconnect installations. Its 1 O, 3-wire (2 legs) configuration and internal thermal disconnector deliver reliable protection for installers and system integrators.

Key Features:

• Surge Protection Device, Combiners/Disconnects type
• Voltage rating 300VAC, max operating 300VAC
• Nominal range 0-250 VAC, 0-600 VDC
• Surge current 80kA per phase, SCCR 10kA
• MCOV 470V, VPR line to ground 1200V
• VPR at 600V/3kA rated 1200V
• 1 O, 3-wire configuration (2 legs)
