{"product_id":"ehc3040","title":"Cutler Hammer EHC3040 - 40A, 480VAC, 3-Pole, Circuit Breaker","description":"\u003cdiv\u003eThe Cutler Hammer EHC3040 40A, 480VAC, 3-Pole Circuit Breaker is engineered for dependable overcurrent protection in demanding industrial environments. Built to guard three-phase distribution, this 3-pole design ensures synchronized disconnection across all phases, helping prevent equipment damage from unbalanced faults and short circuits in high-energy applications. Key specifications at a glance\n- Current rating: 40A\n- Voltage rating: up to 480VAC\n- Poles: 3-Pole\n- Type: Circuit Breaker\n- Ideal for panelboards, switchboards, and control panels in industrial, commercial, and OEM settings Why this breaker stands out\n- Three-phase reliability: The 3-pole configuration provides uniform protection for all phases, reducing the risk of phase imbalances and providing consistent motor and load protection in MCCs and panelboards.\n- High-voltage versatility: Designed for 480VAC systems, making it a practical choice for mid-to-large scale electrical distributions common in manufacturing floors, packaging lines, and HVAC installations.\n- Trusted lineage: Cutler Hammer (Eaton) has a long-standing reputation for rugged build quality and dependable performance in harsh environments, from factory floors to automated production lines. Ideal use cases\n- Motor control centers (MCCs) and manufacturing panels where three-phase motors and drives require coordinated protection\n- Large commercial distribution panels and switchboards that operate at 480VAC\n- OEM equipment and machinery where a reliable 3-pole breaker at 40A is needed to safeguard circuits without complicating interlocks or trip coordination How this breaker supports safer operation\n- Proactive protection for critical loads: By interrupting all three phases simultaneously, it minimizes the chance of latent fault conditions that could escalate into equipment damage or downtime.\n- Simple integration: Its 3-pole footprint aligns with standard industrial enclosures and mounting schemes, enabling straightforward replacement or upgrades in existing systems. Practical tips for deployment\n- Ensure the 40A rating matches the full-load current of the protected circuit, and coordinate with upstream protection to achieve proper selectivity.\n- Use in panels and MCCs that operate at or near 480VAC to maximize protection without overrating the system.\n- Keep documentation and labeling clear on the distribution panel so maintenance teams recognize the exact protection provided by this EHC3040 unit. In short, the Cutler Hammer EHC3040 is a precise, robust solution for safeguarding three-phase circuits at 40A and up to 480VAC, delivering reliable protection in panelboards, switchboards, and motor control centers where uptime and safety are non-negotiable.\u003c\/div\u003e","brand":"Cutler Hammer","offers":[{"title":"Default","offer_id":46390639526050,"sku":"EHC3040","price":76.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/8094\/6850\/files\/circuit_breaker_generic_2bcb19b3-407b-442e-a054-80bffcb0c6a1.png?v=1765378843","url":"https:\/\/www.ampstate.com\/products\/ehc3040","provider":"Ampstate Electric Corporation","version":"1.0","type":"link"}
