High-Quality and Reliable Disconnect Switch for Solar Systems
The Din Rail isolation switch YC1SC8 series (4-Pole) is designed for DC power systems up to DC1200V with rated current up to 32A. It allows simultaneous disconnection of up to 4 MPPT lines, making it ideal for complex solar setups.
This isolator is used for infrequent manual switching and safe disconnection in photovoltaic systems. Typical applications include control cabinets, combiner boxes, and DC distribution panels.
Standards: IEC/EN60947-3, AS60947.3, UL508i
Complete 4-Pole Isolation:
Efficiently isolates four DC circuits at once, ensuring no current flows during maintenance, thereby guaranteeing operator safety.
Robust Build Quality:
Constructed with premium materials, this isolator is durable and long-lasting, even in harsh environmental conditions.
Space-Saving DIN Rail Design:
Its compact design ensures a tidy and space-efficient installation on standard DIN rails.
Easy to Install:
The snap-on DIN rail system enables quick installation for both new systems and upgrades.
UV Resistant & Flame Retardant:
Ideal for outdoor PV installations, thanks to its weather-resistant and flame-retardant housing.
Solar PV Systems:
Disconnect and isolate multiple solar strings (MPPTs) safely from the inverter/DC circuitry.
DC Power Distribution:
Suitable for residential, commercial, and industrial DC disconnection needs.
Maintenance & Safety:
Essential for system upgrades, troubleshooting, or servicing, providing full protection against live DC hazards.
