Eaton EHD3025 - 25 A, 480 V, 3-Pole Bolt-On Circuit Breaker | AmpState

Eaton EHD3025 is a purpose-built bolt-on molded case circuit breaker designed to deliver reliable branch circuit protection in panelboards and loadcenters. With a 25A rating and 480V three-phase capability, this 3-pole device is engineered for environments that demand steady protection and robust mechanical stability. Key benefits that set the EHD3025 apart - Secure bolt-on mounting for a rigid, vibration-resistant bus connection, helping maintain consistent electrical contact in panels subject to movement or vibration. - Thermal-magnetic trip unit that delivers stable, repeatable protection performance across a range of temperatures and load conditions, reducing nuisance trips while safeguarding equipment. - Seamless compatibility with matching OEM loadcenters and panelboards, streamlining installation and maintenance when upgrading or expanding existing systems. - Three-pole design suited for 480V three-phase distribution, providing balanced protection for commercial and light-industrial electrical circuits. - Ideal for protecting branch circuits from overcurrent and short-circuit events, helping to prevent equipment damage and downtime. Technical snapshot - Manufacturer: Eaton - Part Number: EHD3025 - Type: Thermal-magnetic molded case circuit breaker - Amperage Rating: 25A - Voltage Rating: 480V - Number of Poles: 3 - Mounting Style: Bolt-on - Application: Branch circuit overcurrent and short-circuit protection Who this is for - Electrical contractors, facility managers, and electricians installing or upgrading panelboards in commercial or light-industrial settings. - Projects where a secure, vibration-resistant connection is important, such as equipment rooms, mechanical spaces, or areas with higher ambient movement. - Replacements or add-ons that require a compatible, OEM-spec bolt-on breaker to maintain panel integrity and coordination with existing protection schemes. What problems this solves - Reduces risk of loose connections in panels exposed to vibration or movement thanks to bolt-on mounting. - Delivers predictable protection with a thermal-magnetic trip curve that remains stable across typical operating temperatures. - Lowers integration effort by matching OEM panelboard compatibility, ensuring a smoother upgrade path and fewer compatibility issues during installation. Practical tips for use - Verify panelboard compatibility with the Eaton EHD family to ensure uninterrupted coordination with upstream protection devices. - In three-phase systems, install the EHD3025 where consistent trip behavior and reliable trip timing are critical to downstream equipment protection. - When upgrading from a non-bolt-on solution, plan for a secure mounting process to maximize bus connection integrity and long-term reliability. - Use in applications where 480V distribution is standard and 25A protection is appropriate for the protected loads, such as light-industrial distribution circuits or commercial equipment feeds. In short, the Eaton EHD3025 combines dependable thermal-magnetic protection with a rugged bolt-on design, delivering durable, OEM-compatible circuit protection for demanding panelboards and loadcenters. It’s a precise, reliable choice for safeguarding three-phase distribution in commercial and light-industrial environments.
