Protect motors: Electronic overload device

Pittsburgh, PA—The C396 Electronic Overload motor protective device from Eaton Corp. measures motor current, enabling it to model a motor’s thermal condition. The C396 identifies excessive current or “loss of phase” more accurately than traditional bi-metallic overloads, company says, reacting to the motor stress conditions with greater speed and reliability.

Pittsburgh, PA —The C396 Electronic Overload motor protective device from Eaton Corp. measures motor current, enabling it to model a motor’s thermal condition. The C396 identifies excessive current or “loss of phase” more accurately than traditional bi-metallic overloads, company says, reacting to the motor stress conditions with greater speed and reliability.

“Eaton has significantly invested in the research and design of the C396,” says Zari Talebi, marketing communications specialist. “As a result, we’re able to give customers a reliable and flexible option to meet their motor protection needs.”

The C396 is a flexible option for applications that require: Motor overload, phase unbalance, and phase failure protection. It also has low energy consumption, minimizing temperature rise issues inside control cabinets and has a noticeable impact on energy costs, an advantage other products do not offer, Eaton says.

The C396’s reduces inventory stocking requirements and the associated carrying costs with its wide 5:1 full load ampere range, reducing required catalog numbers by more than half, compared to a traditional bi-metallic alternative. This also allows for greater installation flexibility for dual voltage machines. The device, said to be cost-effective, with quick and easy set-up, comes standard with a selectable manual/automatic reset. It is available as a stand-alone device with a current range from 0.1 to 150 A, which can be increased to 1,500 A with an external current transformer kit and selectable trip class 5, 10, 20 or 30. The product also will be offered as starters in conjunction with XT IEC Power Control, Freedom Series NEMA Power Control and DP Control products.
