Accurate, Flexible Protection While electromechanical overload relays pass motor current through heating elements to provide an indirect imitation of motor heating, the C396 electronic overload directly measures motor current through integrated current transformers, more accurately predicting motor overload potential. The electronics identify excessive current or phase loss more accurately and react to the condition with greater speed, reliability and repeatability than a traditional electromechanical device. Because the second leading cause of motor Panel Mounting Adapter (Optional) Line Terminations Identification Marking Strip Tamper Proof Cover FLA Setting Dial Mechanical Trip Actuator Reset Button (Selectable Manual/Automatic) Trip Status Indicator Isolated Auxiliary Contacts—1NO/1NC DIP Switches for Selectable Trip Class Load Terminations failure is phase loss, the C396 has a phase loss detection circuit that protects against lengthy motor overheating and quickly relieves motor stress. Whereas electromechanical overloads can take up to 40 seconds to respond to a phase loss condition, the average reaction time for the C396 is just 3 seconds! Easy to select and apply, the selfpowered design means that no external power source is required, allowing the C396 overload to be installed just like a traditional electromechanical overload relay. Device set-up is quick and easy; simply dial the setting potentiometer to the motor FLA rating and the overload is ready to protect. To further improve application flexibility, the C396 comes standard with a selectable trip class (5, 10, 20, 30) setting and can be used in single-phase or three-phase power applications. There is no need to order different part numbers—the C396 can handle both applications in the same unit. Other features that allow the C396 to provide highly accurate protection include: • Setting accuracy +/– 5% (electromechanical is approximately 10–15%) • Repeat accuracy +/– 1% • Phase imbalance protection to maximize permissible motor output Not only does the C396 provide accurate, reliable protection for your motor, but it allows you the flexibility you need to keep your motors running at their highest possible potential.

45 Amp Frame 110 Amp Frame 150 Amp Frame Superior Performance and Safety Under Any Conditions The C396 has been tested to operate from –25ºC to 65ºC and to withstand 6G of vibration and 15G of shock. Your application could be on a mountain, up to an altitude of 2000M, or in a jungle at 95% humidity. Reliability under every conceivable environmental condition is an important concern and is built into the design of the C396. Not only will it withstand harsh conditions, but it will do so for years—there is no need to continuously replace the unit because of harsh environmental conditions. Most industrial applications typically call for an overload relay that must be manually reset in the event of a trip. This allows the cause of the overload to be identified before the motor is restarted. However, in specialized cases where restarting the motor won’t harm people or equipment, an automatic reset may be desired. The C396 comes standard with a selectable manual/automatic reset, so the desired mode can be chosen for the specific application. The C396 also displays a large current setting knob for ease of Keeping Your Costs Down Using an electronic overload like the C396 not only lowers the amount of electrical energy used in the application, but it can also affect how the control cabinet is designed. The low energy consumption minimizes temperature rise issues inside the control cabinets, enabling panels to be designed smaller and more products to be added into the same enclosure. Even with higher product density in a panel, low power consumption means there is less energy and heat to remove from the panel, lowering the cost of ventilation and cooling requirements. Also, the ability to directly mount the overload to Eaton’s IEC, NEMA and DP contactors further reduces potential enclosure sizes as there is no need for additional spacing for wiring. Not only is the C396 an energy reducing choice for motor protection, its wide 5:1 FLA range reduces the total number of units needed to cover a wide monitoring range. Electromechanical overloads typically have a small current adjustment range, of 1.5 to 1, which means that the maximum setting is about 1.5 times the lower setting. The wide range of the C396 results in the need for less than half as many catalog numbers as a traditional electromechanical alternative, all while covering the same current range. By standardizing installation and a current adjustment shield is included with each overload to protect against the setting being accidentally altered. So that you know the status of your machinery at all times, the C396 has a visible indication to alert the user to the status of the device. Keeping your systems running at peak performance, while maintaining the integrity of your application and the safety of your personnel, are what make the C396 the smart choice for motor protection. on a selectable reset function and selectable trip class settings, the C396 minimizes project engineering work (less configurations), logistics costs, and capital tie-up in inventory variants. The wide current adjustment range also offers greater installation flexibility for dual voltage machines and gives you the ability to better plan for inventory and service. Using the C396 electronic overload is one way to be sure that you are doing all you can to reliably protect your motor and keep your costs down. Meeting and exceeding your expectations for performance is why the C396 is the perfect solution for your every application.
