A-B 140G-J6F3-D15 Programmable controller

Allen-Bradley 140G-J6F3-D15 Overview

The Allen-Bradley 140G-J6F3-D15 is a Molded Case Circuit Breaker (MCCB). It is primarily used to provide overcurrent and short-circuit protection for electrical circuits. As part of the 140G series, it is designed to offer reliable circuit protection with specific ratings and characteristics.

Product Detailed Description

• Function:

• Provides overcurrent protection to prevent damage to electrical equipment and wiring due to excessive current.

• Provides short-circuit protection to quickly interrupt the circuit in the event of severe electrical faults and reduce fire risk.

• Can be used as a manual switch for circuit energization and de-energization.

• Features:

• Thermal-magnetic trip unit: Combines thermal overload tripping (responds to sustained overcurrents) and magnetic short-circuit tripping (responds to rapid, high currents).

• Fixed mount.

• Three-pole (3-pole) configuration.

• May include an indicator to show the tripped status.

• Rugged industrial design.

Product Parameters

Due to the specific model number, the following are inferences based on the code and common parameters for the general 140G series. Always refer to the official datasheet for the specific 140G-J6F3-D15 model for accurate parameters:

• Frame Size:

• J Frame
