Eaton EHD2040L Molded Case Circuit Breaker 40A 2P

Product Description

The EATON EHD2040L is a molded case thermal magnetic circuit breaker designed to provide overcurrent and short-circuit protection in commercial and industrial power distribution systems. This 2-pole breaker is rated at 40 amps and uses a thermal magnetic trip mechanism that responds to both sustained overloads and instantaneous fault currents. The molded case construction houses the internal components in a durable insulated enclosure, making it well suited for panelboard and switchboard installations. Licensed electricians and industrial maintenance technicians are the primary installers of this device.

This breaker is used in load centers, panelboards, and distribution boards where reliable branch circuit or feeder protection is required. The EHD2040L fits applications in light commercial buildings, industrial facilities, and equipment control panels where a compact 2-pole molded case breaker is needed. It is appropriate for protecting motors, HVAC equipment feeders, and general electrical distribution circuits operating on standard 120/240-volt systems.

Key Features

• Thermal magnetic trip mechanism for dual-mode overcurrent protection
• 2-pole configuration for single-phase branch or feeder circuit protection
• 40-amp continuous current rating
• Molded case construction for durable, enclosed component protection
• Compact form factor suitable for standard panelboard and switchboard installations

Compatibility

Designed as an OEM-style molded case circuit breaker for use in compatible EATON panelboards and switchboards that accept EHD-frame breakers. Refer to the panelboard manufacturer specifications to confirm frame and interrupting rating compatibility before installation.

Installation Notes

Installation must be performed by a qualified licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize and lock out the panelboard or switchboard before removing or installing any circuit breaker. Verify that the bus stab configuration and interrupting rating of the breaker match the requirements of the enclosure. Do not exceed the breaker ampere rating for the connected load.
