ABB DC switch-disconnectors for 16–32 amperes have various DC voltage ratings with the same footprint area. The switches are specifically designed for DC use.
Despite its compact size, the product’s insulation voltage ratings are good. Due to its modular design the rated operational voltage can be scaled according to user needs, all the way up to 1000 V. This ensures safe and reliable PV systems at a wide voltage range.
The product has rising PV system voltages. It meets the standard thermal requirements even in elevated temperatures and is suitable for warm locations. Low resistive losses minimise the waste of energy, which helps in maximising total energy efficiency of the PV system.
The application is cool and energy efficient. It has simple installation, with the DC-rated switch-disconnectors suitable for screw or DIN rail mounting. Tunnel terminals capture fine stranded wires and they are wide enough to allow wires up to 16 mm2. It has short-circuit bars as standard.
