The KAEL ATS 125A (LDQ5 Series) is a high-performance dual power automatic transfer switch designed to ensure uninterrupted electricity for residential and industrial loads. With a robust 125A current rating, this 4 pole ATS is specifically engineered to handle 3-phase systems, providing simultaneous switching for all three phases and the neutral line. It automatically detects power failure from the primary source and shifts to the backup source (generator or inverter) in under 2 seconds.
At Enon Traders, we recommend the KAEL 125A ATS for large-scale solar inverters setups where net-metering and backup reliability are critical. Its compact DIN-rail design allows for easy integration into your existing distribution board. For a complete power management solution, pair this ATS with our high-quality flexible wire 16mm square for internal panel wiring and flexible pipe 1 inch for cable protection.
