Suntree 250A 1000V DC MCCB 2 Pole Solar Circuit Breaker

Description

1. The SUNTREE 250A DC MCCB 2P is a photovoltaic-rated DC molded case circuit breaker designed to protect solar PV strings, combiner boxes, and battery-to-inverter cabling, with a rated voltage up to DC 1000V. It’s built for installers and off-grid/hybrid solar integrators who need reliable overload and short-circuit protection on DC lines carrying up to 250A.

Key Features

• 250A rated current, 2-pole (2P) configuration for DC circuits
• Rated voltage up to DC 1000V — suitable for high-voltage solar PV and battery strings
• Overload long-delay protection guards equipment against sustained overcurrent
• Short-circuit instantaneous protection for fast fault clearing
• Quick-closing, fast-breaking operating mechanism
• Compact molded case design, easy to fit in combiner boxes and DC panels
• Doubles as a manual DC isolator for battery-to-inverter shutoff

Why Choose the SUNTREE 250A DC MCCB?

SUNTREE builds DC-specific protection devices for photovoltaic systems rather than adapting AC breakers — DC faults sustain an arc differently, so a DC-rated breaker matters. Its DC 1000V rating comfortably covers most high-voltage string and battery-bank setups used in commercial and hybrid solar installations across Nigeria. SUNTREE’s DC MCCB range is generally built to IEC 60947-2, the international standard for DC molded case circuit breakers.

Applications

• Solar PV combiner boxes and DC distribution panels
• Protection between PV strings and the inverter
• Battery bank to inverter protection and manual isolation/shutoff
• Commercial and industrial hybrid solar power plants
• Off-grid solar installations
