Solar MCCB Switch 160A for 1000V DC Protection
The 2P-160A / 1000V DC solar MCCB circuit breaker is specifically designed for the protection of photovoltaic installations, lithium or lead-acid battery systems, and electric vehicles. It automatically intervenes in case of short circuit, overload, or overvoltage, preventing damage to the inverter and batteries. A robust solution for any solar system requiring fast and safe DC circuit isolation.
What you get with this product
- Complete DC circuit protection — automatically disconnects in case of short circuit, overload, and overvoltage, without manual intervention
- Compatible with DC voltages up to 1000V — suitable for photovoltaic installations, lithium-ion batteries, lead-acid batteries, and electric vehicles
- Rated current 160A — supports high loads specific to solar systems with high-capacity batteries
- Fire-retardant ABS housing — the material chars instead of igniting, limiting the spread of a potential fire
- Quick mounting on DIN rail or directly on panel — includes fixing screws, no special tools required
- 8kV impulse withstand voltage — protects connected equipment against transient voltage spikes
How it works and how to install it
The MCCB switch is installed in series on the DC circuit, between the power source (solar panels or batteries) and the inverter or distribution board. The connection is made on clearly marked bipolar terminals, using cables of appropriate cross-section for the operating current. The kit includes mounting screws and terminal protection covers, so installation can be performed directly by an authorized electrician without additional parts.
Frequently Asked Questions
Can I use this switch in an off-grid photovoltaic system with lithium batteries?
Yes, the 2P-160A MCCB switch is explicitly recommended for systems with lithium-ion batteries, installed between the battery and the inverter for short circuit and overload protection.
What happens if the voltage exceeds 1000V DC in the installation?
The switch is approved for an isolation voltage (Ui) of 1000V DC; use above this value is not recommended and may compromise the safety of the protection.
It is bipolar — does that mean it interrupts both poles of the DC circuit simultaneously?
Yes, the 2P version simultaneously interrupts both conductors of the DC circuit, which is mandatory for safety in photovoltaic installations according to current regulations.

Inspired to create a chair where the backrest and armrests are molded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.
