Siemens ED23B040L Circuit Breaker 3P 240V 40A

Product Description

The SIEMENS ED23B040L is a 3-pole molded case circuit breaker rated for 240 volts and 40 amps, designed for overcurrent protection in commercial and industrial power distribution panels. This breaker interrupts fault current automatically and provides manual disconnection of three-phase or multi-wire branch circuits. Licensed electricians install this type of device in load centers, panelboards, and switchboards where reliable branch-circuit protection is required. Its compact ED2 frame construction is suited for installations where panel space is a consideration.

This breaker is applied in commercial and light industrial settings requiring 3-pole, 240-volt branch circuit protection. Typical applications include HVAC equipment disconnects, motor branch circuits, and multi-wire feeder protection in commercial panelboards. It is installed by licensed electricians in accordance with NEC requirements for overcurrent protective devices on three-phase and split-phase systems.

Key Features

• 3-pole configuration for three-phase or multi-wire 240-volt branch circuits
• 40-amp continuous current rating for branch and feeder circuit protection
• ED2 frame series for compatibility with Siemens panelboard applications
• Automatic trip mechanism provides overcurrent and short-circuit protection
• Manual ON/OFF switching for safe disconnection during service

Compatibility

Designed as an OEM-style replacement or direct-fit circuit breaker for panelboards and load centers accepting ED2 frame series breakers.

Installation Notes

Installation must be performed by a licensed electrician in compliance with the National Electrical Code (NEC) and all applicable local codes. De-energize the panel and verify absence of voltage with a calibrated meter before handling any breaker or bus connection. Confirm that the breaker frame rating and interrupting capacity are appropriate for the available fault current at the point of installation. Do not install a breaker with a current rating that exceeds the ampacity of the connected conductors.
