DC MCCB 3P 1500V 15KA

Noark Ex9MV2S-PV – 1500 V DC Moulded Case Breaker for PV Systems

The Ex9MV2S-PV series is engineered specifically for photovoltaic (PV) and other high-voltage DC applications. With a rated operational voltage up to 1500 V DC and heavy-duty interrupting capability, this breaker brings commercial-grade reliability to solar string and combiner-box installations.

Key Features

• Designed for PV environments – rated for up to 1500 V DC.
• Frame currents up to 250 A for high-power arrays.
• Impressive breaking capacity – up to 15 kA at 1500 V DC.
• Rated impulse withstand voltage (Uimp) of 12 kV for enhanced insulation performance.
• Built-in isolation functionality so the breaker can act as a disconnect point for safe maintenance access.
• Wide ambient temperature range and robust mechanical life, designed for demanding outdoor solar environments.

Typical Applications

Use the Ex9MV2S-PV series wherever you need a dependable DC circuit-breaker in a high-voltage PV setup: string combiner boxes, inverter DC inputs, or large battery/DC systems with solar tie-in.

Installation Highlights

• Install close to your inverter or combiner box for maximum safety and efficiency.
• Use appropriate lugs or bus-bar connections rated for 1500 V DC systems.
• Ensure correct polarity, cable sizing and adherence to PV system grounding/earthing standards.
• Option to add accessories like auxiliary contacts, shunt trips, or handle interlocks for full system integration.

Whether you’re designing rooftop arrays, ground-mount solar farms or retro-fitting high-voltage DC systems, the Ex9MV2S-PV series gives you a safe, high-performance breaker built for the real demands of PV.
