DC Circuit Breaker SUNTREE 2P – 63 A – 800 VDC (MCB)
This breaker belongs to the SL7N-63 series from SUNTREE, a range of miniature circuit breakers designed for direct current (DC) systems, suitable for installations up to approximately 800 V DC — ideal for photovoltaic solar systems, batteries, and other high-voltage DC applications.

Technical Characteristics

General

Brand: SUNTREE

Series / Model: SL7N-63 (2-pole DC version)

Type: Miniature circuit breaker for DC

Number of poles: 2P — disconnects both + and − lines

Rated current: 63 A

Rated DC voltage: 800 V DC — suitable for high-voltage DC systems (solar, storage)

Protection & Performance

Overload and short-circuit protection — automatic disconnection when limits are exceeded

High breaking capacity: up to 6 kA — capable of interrupting significant faults quickly

Contact opening distance (> 8.5–9 mm) — ensures effective interruption of DC electrical arcs

Silver-graphite contacts — improved conductivity and reliability

Arc-quenching design with special plates for enhanced safety

Additional Features

Non-polarized: can be connected without concern for + or − orientation

DIN rail mounting (35 mm) — easy installation in electrical panels

Protection rating: IP40 (housing) / IP20 (terminals)

Operating temperature: -30°C to +70°C

Compliant with standards: IEC 60947-2, CE, CB, TUV (depending on version)

Functions & Uses

This DC 2P – 63A – 800VDC breaker is used to:

Protect against overloads

Quickly interrupt short circuits

Isolate both poles (+ and −) for enhanced safety

Secure solar energy systems and DC storage installations

Typical Applications

Protection of photovoltaic solar circuits

Protection of battery storage lines

Industrial DC installations

Why It Is Essential

In high-voltage DC circuits, electrical arcs are difficult to extinguish. A breaker specifically designed for DC ensures safe and effective disconnection, protecting equipment and improving overall system safety in solar and energy storage applications.
