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\n- Secure bolt-on mounting for a rigid, vibration-resistant bus connection, helping maintain consistent electrical contact in panels subject to movement or vibration.\n- Thermal-magnetic trip unit that delivers stable, repeatable protection performance across a range of temperatures and load conditions, reducing nuisance trips while safeguarding equipment.\n- Seamless compatibility with matching OEM loadcenters and panelboards, streamlining installation and maintenance when upgrading or expanding existing systems.\n- Three-pole design suited for 480V three-phase distribution, providing balanced protection for commercial and light-industrial electrical circuits.\n- Ideal for protecting branch circuits from overcurrent and short-circuit events, helping to prevent equipment damage and downtime. Technical snapshot\n- Manufacturer: Eaton\n- Part Number: EHD3025\n- Type: Thermal-magnetic molded case circuit breaker\n- Amperage Rating: 25A\n- Voltage Rating: 480V\n- Number of Poles: 3\n- Mounting Style: Bolt-on\n- Application: Branch circuit overcurrent and short-circuit protection Who this is for\n- Electrical contractors, facility managers, and electricians installing or upgrading panelboards in commercial or light-industrial settings.\n- Projects where a secure, vibration-resistant connection is important, such as equipment rooms, mechanical spaces, or areas with higher ambient movement.\n- 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\n- Reduces risk of loose connections in panels exposed to vibration or movement thanks to bolt-on mounting.\n- Delivers predictable protection with a thermal-magnetic trip curve that remains stable across typical operating temperatures.\n- Lowers integration effort by matching OEM panelboard compatibility, ensuring a smoother upgrade path and fewer compatibility issues during installation. Practical tips for use\n- Verify panelboard compatibility with the Eaton EHD family to ensure uninterrupted coordination with upstream protection devices.\n- In three-phase systems, install the EHD3025 where consistent trip behavior and reliable trip timing are critical to downstream equipment protection.\n- When upgrading from a non-bolt-on solution, plan for a secure mounting process to maximize bus connection integrity and long-term reliability.\n- 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.\u003c\/div\u003e","brand":"Amp State","offers":[{"title":"Default Title","offer_id":46349554024610,"sku":null,"price":710.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/eaton_breaker_and_panels_d896e7cc-1c13-4ce1-ac52-908a7fb9adb8.png?v=1764149518","url":"https:\/\/www.ampstate.com\/products\/eaton-ehd3025-25a-480v-3-pole-bolt-on-circuit-breaker","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
