Suntree SM8-250HPV 250A 1000V DC Solar Circuit Breaker

The Suntree SM8-250HPV 250A 1000V DC moulded-case circuit breaker (MCCB) is designed for compatible high-voltage solar photovoltaic (PV) and DC distribution systems. It helps protect circuits and connected equipment against overloads and short circuits when correctly selected and installed.

The 250A model uses a 250A frame and is available in different rated-current configurations. The 1000V DC version is documented as a 2-pole breaker, making it suitable for compatible DC circuit arrangements where its voltage, current and short-circuit ratings meet the system requirements.

Available from Coastalsolar Africa for solar installers, electrical contractors, commercial projects and customers across Mombasa, Kilifi, Malindi, Watamu, Diani, Ukunda, Kwale and other coastal towns in Kenya.

Technical Specifications

Applications

• Commercial and industrial solar PV systems
• High-voltage DC distribution
• Compatible solar power system protection
• Selected battery and DC power circuits where the manufacturer permits
• DC distribution panels designed for the breaker’s specifications

Installation and Safety

This is a DC circuit breaker, not an AC-rated substitute. Verify the exact model suffix, pole arrangement, maximum system voltage and short-circuit breaking capacity before installation.

A 250A breaker must be selected to match the protected cables, equipment and prospective fault current. Do not assume that a high current rating makes the breaker suitable for every inverter or battery system. Installation should be performed by a qualified electrician or solar technician in accordance with the manufacturer’s wiring instructions.

For installations in Kenya’s coastal region, use a suitable enclosure and installation practices that help protect against moisture and salt-laden air.
