DESCRIPTION
Yokins Instruments Pvt. Ltd. Current monitoring relays are incredibly accurate. Our Numerical Current monitoring relay is fully programable with exact setting of setpoints it offers very good accuracies. This means that your equipment is always protected from overcurrent and under current conditions. Our current monitoring relays are designed to be incredibly reliable, with a long lifespan and a high MTBF (mean time between failures). This means that you can be confident that your equipment will always be protected, even in the most demanding environments.
We are the leading Current Monitoring Relays manufacturers and suppliers, our current monitoring relays also known as CMR are manufactured to the highest quality standards, using only the best components. They can be customized for various ranges as per customer’s specific requirement, which makes it very versatile product.
