Solar photovoltaic (PV) systems (residential and industrial)

Direct current (DC) distribution boxes

Battery system (accumulator) circuit protection

Inverter protection

Microinverter and solar panel string fuses

Pros:

High breaking capacity – up to 6kA ensures safety even under heavy loads

Wide voltage range – from 12V to 1000V DC

Compact size, ideal for limited installation space

Long service life – up to 20,000 mechanical cycles
