IMO DC Disconnect Rooftop Isolator Switch SI32-PEL64R-4
Ensure the highest level of safety and compliance for your photovoltaic system with the IMO DC Disconnect Rooftop Isolator Switch SI32-PEL64R-4. Engineered by IMO Precision Controls, this true DC isolator is purpose-built to reliably disconnect your DC/AC inverter from solar panels, meeting the stringent requirements of IEC 60364-7-712 for all photovoltaic installations. Priced at $96.95, this premium switch delivers uncompromising performance, robust construction, and peace of mind for both residential and commercial solar arrays.
Unlike standard AC switches that are merely de-rated for DC use, the SI32-PEL64R-4 is a true DC switch—designed from the ground up to handle the unique challenges of direct current. Its operator-independent switching mechanism, high-speed trigger ratchet action, and IP66-rated self-extinguishing plastic enclosure ensure safe, reliable operation in even the harshest rooftop environments. With knife-edge contacts, arc cooling chambers, and a lockable off feature, this isolator provides superior protection for your system and personnel.
