Allen-Bradley 193-EC5 E3 Plus solid-state overload relay

The Allen-Bradley 193-EC5 E3 Plus solid-state overload relay features voltage protection and energy monitoring. Part of the E3 Plus family, the overload relay combines current and voltage protection with enhanced power monitoring and diagnostic capabilities.

The overload relay is designed for low voltage applications in materials handling, water and wastewater, process, petrochemical and minerals and mining.

Communicating status and diagnostic information using DeviceNet communications with Rockwell RSEnergyMetrix software, the overload relay identifies motors contributing to the monthly peak demand and power factor line items on utility bills. It also assists in activity-based cost accounting and verifying energy-reduction initiatives. In addition, the overload relay is equipped with Allen-Bradley DeviceLogix intelligent component technology, which integrates logic-solving capability into the overload relay. This provides users with basic digital control when a programmable controller is not available. It can also be used to turn off a motor in the event of lost communications within a control system.

The solid-state overload relay also helps protect against voltage issues, such as undervoltage, voltage unbalance, phase loss, frequency and phase rotation, before the contactor coil is energised. While the motor is powering a load, the overload relay protects the motor based on excessive real power (kW), reactive power (kVAR), apparent power (kVA) and power factor. The overload relay accommodates currents ranging from 0.4 to 860 A, as well as currents up to 5000 A using external current transformers.
