Application: Specifically designed for DC applications like photovoltaic (PV) solar panels, battery storage, and inverters.
Configuration: Typically 1-pole or 2-pole, although 4-pole versions exist for complex, higher voltage systems.
Voltage Capacity: Ranging from 250V to 1000V DC, with 550V DC being a common rating for residential solar arrays.
Breaking Capacity: Often features a capacity of ~6kA to 10kA (e.g., SL7-63N model).
Installation: Designed for 35mm DIN rail mounting, making it easy to install in distribution boxes.
Safety: Features fast-acting mechanism and arc quenching components tailored for DC, which lacks a natural zero-crossing point.
