SIM-Q MKII

Protection Relay · Electrical Components & Switchgear

Class-certified type (DNV register) · technical data sheet not yet verified

The SIM-Q MKII monitors the insulation resistance between the connected network and an earth/safety cable. Using a unique measuring principle, it measures the insulation resistance in AC networks up to 690 V and DC networks up to 1000 V.

Free of charge — send us your request for DEIF equipment. Our team checks it and replies by e-mail.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — attach it below or send it as a reply to our confirmation e-mail.
