Allen-Bradley 193-EC2BD Motor Protection Relay

Allen-Bradley 193-EC2BD E3 Plus Electronic Motor Protection Relay is a solid-state motor protection device that mounts directly to a compatible contactor for compact, integrated protection. It is rated 3–15 A and is part of the E3 Plus family, designed to protect small-to-midsize motors from overload and fault conditions. The 193-EC2BD version specifies 4 inputs and 2 outputs, supporting wiring for control signals, alarms, and interlock logic, along with a PTC thermistor input for motor temperature sensing. It also includes an internal ground-fault sensor for enhanced protection in circuits where ground fault conditions must be detected. Built for direct mounting to a contactor, this relay simplifies installation and panel space while delivering precise, solid-state protection characteristics typical of Allen-Bradley motor protection relays. As a member of Rockwell Automation’s 193-E3 Plus line, the 193-EC2BD is commonly used in MCCs and packaged equipment to monitor motor health and automatically trip on abnormal current or temperature, helping to prevent motor damage and unplanned downtime.
