IMO DC Disconnect Rooftop Isolator Switch

The SI32-PEL64R-4 or SI32-PEL64R-2  from IMO Precision Controls is a rotary actuator switch lockable off in a plastic enclosure. This True DC isolator is developed explicitly as a True DC switch to disconnect the DC/AC inverter from the photovoltaic panels. All photovoltaic installations must be equipped with DC isolators per IEC 60364-7-712.

The IMO SI is a True DC switch - not an AC version de-rated or re-wired for DC operation. It includes operator independent switching mechanism, high-speed trigger ratchet switching, IP66-rated enclosure, fully enclosed internal switch without additional wiring for maximum safety, Knife edge contacts and arc cooling chambers, maximum 1Nm torque for easy operation, compact space-saving design, and 16mm² box terminals for easy wiring.
