DROSS DC MCB 63A 2 Pole 600V – Solar DC Circuit Breaker
DROSS DC MCB 63A 2 Pole 600V – Solar DC Circuit Breaker
DROSS DC MCB 63A 2 Pole 600V is designed to provide reliable protection for DC electrical circuits against overload and short-circuit conditions. It is suitable for solar PV systems, battery installations, inverters, DC distribution boxes (DCDB) and other DC electrical applications.
Looking for a DC MCB for solar inverter protection or a solar DC breaker 600V for your home? This 2 pole DC MCB for rooftop solar also works as a PV isolator breaker for home systems, letting you safely switch off the DC side between your panels and inverter.
The 2 Pole design allows simultaneous isolation of both DC lines, providing convenient and effective circuit protection. Its DIN rail mounting design enables quick and easy installation inside electrical and solar distribution boxes.

Compatibility: which system does it fit?
- Voltage: DC systems up to 600V DC. The maximum open-circuit voltage (Voc) of your panel string should stay below 600V.
- Current: up to 63A. Choose a rating about 125% of your normal circuit current, and never above your cable's rating.
- Where it fits: solar PV strings, DCDB boxes, battery-to-inverter circuits, and 12V / 24V / 48V DC systems.
- 2 Pole: switches off both the positive and negative DC lines together, so the circuit is fully isolated. If you only need to switch one line, the 1 Pole version is available.
- Mounting: standard DIN rail.
Solar installer guide: which protection to choose?
| Where in your system | What to use |
|---|---|
| Each panel string, before the combiner box or DCDB | DROSS ZYPV-32X fuse holder (1000V DC, 32A) with a 10×38mm PV fuse link |
| Switching off or isolating a DC circuit (string, DCDB, inverter input) | DROSS DC MCB 63A, 1 Pole or 2 Pole (600V DC) |
| Battery to inverter circuit (higher current) | DROSS DC MCB 125A, 1 Pole |
| Surge and lightning protection at the DCDB or inverter DC input | DROSS DC SPD-40 (Type 2, 600V DC) |
Simple rules: keep your system's maximum DC voltage below the device's voltage rating. Choose the DC MCB current rating about 125% of the normal circuit current (not above your cable's rating), and choose string fuses as per your panel datasheet. Not sure? WhatsApp us your panel wattage, number of panels in series and inverter or battery voltage on +91 99928 08001 and we will suggest the right protection. Installation should be done by a qualified electrician.
