WHY EOCR

By choosing the right protection device, users can ensure longer life from motors and avoid untimely failures resulting in loss of manpower, materials and natural resources like copper for rewinding procedures. Despite having conventional electro mechanical products for motor protection, it is a known fact that motor failures are quite common and lead to excessive costs, downtime and loss of materials in process. which are far greater than the cost of the motor and allied protection equipment.
