E300 / E200 electronic overload relay modules (193 / 592)
21 Allen-Bradley E300 / E200 overload relays (193, 592) catalog numbers, each with the ratings and the lifecycle status shown on its Rockwell product page (read on 3 November 2026). TDL quotes these parts as spares or as part of a project, and handles configuration, programming and commissioning on site.
- An E300/E200 relay is built from separate modules: a sensing module, a control module and, for E300, a communication module; expansion modules add I/O and power.
- Sensing modules come in four current ranges: 0.5…30 A, 6…60 A, 10…100 A and 20…200 A.
- Sensing types are current only (I), current plus ground fault (IG), and voltage, current and ground fault (VIG).
- Communication modules are listed for EtherNet/IP (193-ECM-ETR) and DeviceNet (193-ECM-DNT); E200 uses a Parameter Configuration Module (193-ECM-PCM).
- The analog expansion module 193-EXP-AIO-31 requires control module firmware v3.000 or higher.
How to read the catalog number
- Position 1: 193 = IEC overload relay, 592 = NEMA overload relay.
- Position 2: ESM = sensing module.
- Position 3: sensing type — I = current; IG = current and ground fault current; VIG = current, ground fault current, voltage and power.
- Position 4: current range — 30A = 0.5…30 A, 60A = 6…60 A, 100A = 10…100 A, 200A = 20…200 A.
- Position 5: mounting style — e.g. C23 = mounts to 100-C09…C23 contactor; T = DIN rail/panel mount with power terminals; P = pass-thru; E3T = E3 Plus replacement with power terminals.
- Control module example 193-EIO-43-120: EIO = I/O-only control module; 43 = 4 inputs / 3 relay outputs; 120 = 110…120V AC control voltage. Not every combination is a valid catalog number.
