A-B 193EC2BB Central control module

A-B (Allen-Bradley) 193EC2BB Overview

The A-B 193EC2BB is a thermal overload relay belonging to the Allen-Bradley Bulletin 193 E1 Plus series. It is designed to protect three-phase AC motors from overload and phase loss faults.

Product Detailed Description

• Function:

• Provides overload protection for motors, preventing damage due to overcurrent.

• Offers phase loss protection, tripping the circuit to protect the motor when one phase of the three-phase power supply is lost.

• Features an adjustable current setting range to accommodate motors with different rated currents.

• Typically used in conjunction with contactors to form a complete motor control and protection solution.

• Offers test and manual/automatic reset functions.

• Features:

• Thermal overload protection mechanism.

• Adjustable trip class.

• Phase loss sensitivity.

• Test button for verifying the tripping mechanism.

• Manual and automatic reset options.

• DIN rail mounting.
