Eaton JD3175W - 175 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton JD3175W is a robust 3-pole bolt-on molded case circuit breaker purpose-built for dependable branch circuit protection in panelboards and load centers. With a 175 A rating and a 600 V maximum, this unit is engineered to handle demanding 3-phase circuits in commercial and light industrial environments, while also serving select residential applications that demand solid protection and long-term reliability.

Why the JD3175W stands out

• Secure bolt-on mounting delivers a rigid, vibration-resistant bus connection, reducing loose contacts and ensuring consistent performance in panels subjected to equipment movement or manufacturing environments.
• Thermal-magnetic trip unit provides stable, repeatable protection by combining overload (thermal) protection with instantaneous short-circuit protection (magnetic). This minimizes nuisance trips and responds quickly to dangerous faults.
• OEM-loadcenter compatibility engineered to pair seamlessly with matching Eaton loadcenters and panelboards, simplifying replacement, upgrading, or expansion projects without compatibility concerns.
• Three-pole design guards all three phases with a common trip, essential for balanced loading and safe shutdown of 3-phase equipment.
• Versatile application ideal for branch circuit protection in commercial spaces, data centers, light industrial facilities, and upgraded residential installations that require robust protection against overcurrent and short circuits.
