Eaton CVS3100X - 100 A, 240 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton CVS3100X is a 100A, 240V, 3-pole bolt-on molded case circuit breaker engineered for dependable branch-circuit overcurrent and short-circuit protection in panelboards and load centers. Its robust bolt-on mounting delivers a rigid, vibration-resistant bus connection, helping panels endure demanding environments without compromising safety or performance.

• Secure bolt-on mounting: provides a solid, vibration-resistant connection that stays put through frequent on/off cycles and equipment vibrations.
• Thermal-magnetic trip unit: combines thermal overload protection with instantaneous magnetic trip for fast, predictable responses to short circuits and heavy motor loads.
• 3-pole design: ideal for clean, balanced 3-phase distribution in commercial and light industrial applications.
• 100A, 240V ratings: appropriately sized to protect medium-sized branch circuits and equipment racks without nuisance trips.
• OEM-compatible: designed to pair with matching Eaton OEM load centers and panelboards for seamless replacement and serviceability.
• Durable construction: molded case design built to endure typical building and equipment environments found in residential, commercial, and light industrial settings.
