## Long description

Eti-Polam Rozłącznik LS25 SMA A4 PV is a 4-pole DC isolator switch designed for use in photovoltaic (PV) installations where safe, manual disconnection of DC circuits is required. The device provides a clear mechanical separation of conductors to enable maintenance, troubleshooting and emergency shutdown of solar strings and inverter DC inputs. Its form factor and pole configuration suit common PV system layouts and rooftop arrays.
Advantages
This DC isolator offers a robust mechanical switching mechanism and a compact footprint for panel and combiner-box mounting. It allows visible separation of contacts for straightforward verification of an open circuit. The 4-pole design supports multi-conductor PV strings and provides reliable isolation of positive and negative rails with an additional pole for system grounding or auxiliary circuits. The construction follows industry practices for DC switching in photovoltaic applications.
Suitable for
Manual isolation of PV string inputs to inverters and combiner boxes
Maintenance and repair operations on rooftop and ground-mounted solar arrays
Emergency shutdown procedures and safety isolation during system servicing
Protecting downstream equipment when performing electrical work on DC circuits
Key specifications
Contact configuration: 4-pole DC isolator suitable for photovoltaic systems
Operation: manual rotary or lever actuation providing visible contact separation
Intended use: DC switching and isolation for solar string and inverter inputs
Mounting: panel or combiner-box installation with secure fastening points
Environmental suitability: designed for installation in PV electrical enclosures and sheltered outdoor equipment rooms
How to use
Install the isolator in accordance with electrical codes and the system wiring diagram, ensuring correct conductor sizing and torque values for connections. Use the switch to disconnect DC supply before performing any maintenance or inspection work; verify open-circuit condition visually and with appropriate test equipment.
