The ESR E254PDC/L 1000VDC 25A Rotary Isolator Switch is a high-performance  disconnection device designed for DC solar systems and commercial power control applications. Built for durability and safety, this isolator offers fast arc suppression, knife-edge self-cleaning contacts, and independent ratchet switching, ensuring maximum reliability even under continuous load.
Housed in a compact, IP65-rated ABS/polycarbonate enclosure, it is fully protected against dust and water ingress. The lockable rotary handle provides enhanced safety, while the interlocked lid prevents the cover from being opened unless the unit is in the OFF position.
Tested and approved to IEC60947-2 and VDE0660, this unit carries CE, CB, and SAA certifications — making it a trusted choice for professional-grade solar and industrial DC isolator needs.
