Why use an IMO DC Solar Isolator?

IMO Precision Controls offers a range of True DC Isolators specifically designed for use in Solar PV installations in accordance with EN
60364-7-712. The IMO design incorporates a user independent switching action so as the handle is moved it interacts with a spring
mechanism which, upon reaching a set point, causes the contacts to “SNAP” over thereby ensuring a very fast break/make action. This
mechanism means that the disconnection of the load circuits and suppression of the arc, produced by a constant DC load, is normally
extinguished in 3ms using the specific pole suppression chambers incorporated within the design.

The IMO Solar Isolator range is offered in a number of configurations all rated for
installation and use as switch-disconnects and all with options allowing for
“LOCKABLE OFF” operation. Although able to offer the industry standard two
position 90° handle operation from LOCKABLE OFF-ON, IMO have also introduced
a SAFE-LOCK patented handle that allows for three rotational positions relating
to ON-OFF-LOCK. The facility offered by this design gives a LOCK position that is
removed from the OFF setting ensuring the handle can be placed in its own unique
position when locked, which is fully compliant with IEC 60947-1 section
for classification as an isolator or switch disconnector. When this design is used
within the IMO enclosed Solar Isolators it ensures that engineering access can
only be attained to the enclosure when the handle is in the OFF position; whilst the
“LOCK” position ensures secure power isolation combined with non-access to the
enclosure (when the isolator block is secured with supplied screws) and thereby
significantly reducing the risks of tampering when maintenance/repair is carried
out on equipment in-line after the isolator, SAFE-LOCK. Once any work has been
undertaken the locking mechanism can then be removed and the isolator returned
to its normal operational mode.
