This document provides technical data and selection procedures for Allen-Bradley motor starting solutions, specifically Bulletins 140MP, 100-K, and 193-K. These components are designed to create compact, flexible motor starter configurations for industrial and commercial applications.
System Configurations
The manual outlines two primary configurations for motor starting:
- Two-component motor starter: A simple setup consisting of a 140MP Motor Protection Circuit Breaker (with built-in thermal overload relay) and a 100-K contactor. This is the most compact configuration.
- Three-component motor starter: A more flexible solution consisting of a motor circuit protector (or fuses), a 100-K contactor, and a 193-K motor thermal overload relay.
Selection Steps
Follow these steps to configure your motor starter:
- Choose Circuit Breaker and Optional Connection Module: Select the 140MP breaker based on the rated operating current and thermal trip adjustment range required for your motor.
- Configure Contactor: Select the 100-K contactor. Complete the catalog number by specifying the coil voltage code (e.g., D for 120V AC, DJ for 24V DC) and auxiliary contact configuration (e.g., 10 for 1 N.O., 01 for 1 N.C.).
- Select Motor Overload Relay (Optional): If using a three-component starter, select the appropriate 193-K overload relay based on the thermal trip adjustment range.
Accessories
Various accessories are available to enhance the functionality of the starters:
- For 140MP MPCBs: Front-mounted auxiliary contacts, compact bus bars, bus bar feeder terminals, and IP65 enclosures.
- For 100-K Contactors: Front-mounted auxiliary contacts, power wiring kits for reversing/star-delta combinations, DC diode suppressors, and mechanical interlocks.
Dimensions
The manual provides detailed dimensional drawings for the 100-K miniature contactor with 193-K overload relay and the 140MP-A3E series (up to 16 A). These dimensions are provided in millimeters and inches for planning purposes.

Practical help
Common problems
Motor overload tripping
Ensure the thermal trip adjustment range on the 140MP or 193-K relay is correctly set to match the motor's rated operating current.
Incorrect coil voltage
Verify the coil voltage code (D, B, KJ, KF, DJ) matches your control circuit requirements before ordering the 100-K contactor.
Before use
- Determine if a two-component or three-component starter configuration is required.
- Verify the motor's rated operating current (A).
- Check the required thermal trip adjustment range.
- Identify the necessary coil voltage for the contactor.
- Select appropriate auxiliary contacts based on control needs.
- Verify if accessories like bus bars or suppressors are needed for the installation.
Specs in practice
- Trip Class 10
- Standard protection class for 140MP devices; does not require a separate overload relay unless using fuses or a breaker without thermal protection.
Images and diagrams
- Two-component starter: 140MP breaker + 100-K contactor.
- Three-component starter: Circuit protector/fuses + 100-K contactor + 193-K overload relay.
Model compatibility
- 140MP devices are UL Listed as Manual Motor Controllers.
- 100-K contactors are compatible with 193-K overload relays.
- Accessories for 140MP and 100-K are specific to their respective series.
