Why Choose the IMO SI16-PEL64R-2 DC Isolator Switch?
The IMO SI16-PEL64R-2 is a high-performance 16 A two-pole enclosed DC isolator switch specifically designed for solar photovoltaic (PV) installations. Developed as part of the proven IMO SI True DC Isolator Series, it provides safe and reliable isolation between PV arrays and inverters, ensuring compliance with modern photovoltaic installation standards.
Unlike AC switches adapted for DC use, the SI16-PEL64R-2 is engineered specifically for DC switching. It incorporates a spring-assisted operator-independent switching mechanism, knife-edge contacts and integrated arc suppression chambers that extinguish DC arcs in approximately 3 ms, helping maximise safety and switching performance.
Supplied in a durable IP67-rated thermoplastic enclosure with a lockable rotary handle featuring IMO's SafeLock ON/OFF/Lock function, this isolator is ideal for residential, commercial and industrial solar PV systems. Its compact enclosed design simplifies installation while providing dependable long-term protection in demanding outdoor environments.
