Eaton KDC3200Y - 200 A, 600 V, 3-Pole Bolt-On Circuit Breaker | AmpState

The Eaton KDC3200Y is a rugged 200A, 600V, 3-pole bolt-on molded-case circuit breaker designed to deliver dependable branch circuit protection for panelboards and load centers. Built for durability in residential, commercial, and light industrial environments, it offers a secure connection and reliable protection when it matters most.

Why the Eaton KDC3200Y stands out

• Secure bolt-on mounting provides a rigid, vibration-resistant bus connection, reducing the risk of loose connections that can lead to nuisance trips or uneven protection.
• Thermal-magnetic trip unit delivers stable, repeatable protection by combining overload and short-circuit sensing in a single, reliable mechanism.
• 3-pole design for 3-phase systems with a 200A rating ensures comprehensive protection for larger panels and equipment fed from three-phase circuits.
• 600V voltage rating makes it suitable for common distribution setups in commercial and light-industrial installations.
• OEM load center compatibility is engineered to pair with matching Eaton panelboards and other OEM enclosures, ensuring seamless fit and performance.

How it protects your electrical system

As a thermal-magnetic molded-case circuit breaker, the KDC3200Y reacts to gradual heat buildup from overcurrent and to rapid magnetic surges from short circuits. The thermal element modulates trip timing for mild overloads, while the magnetic element provides immediate response to dangerous fault currents. The result is precise protection that helps prevent conductor damage, component wear, and fire risk, while keeping downtime to a minimum.

Ideal applications and use cases

This 200A, 600V, 3-pole bolt-on MCCB is well-suited for:

• Residential and commercial panelboards requiring robust branch-circuit protection
• Load centers where a secure, vibration-resistant connection is critical (e.g., areas with equipment vibration or building movement)
• New installations and panel upgrades that demand compatibility with OEM enclosures and reliable protection for 3-phase circuits
• Light industrial applications where dependable protection and rapid fault interruption are essential for safety and uptime

Practical considerations and tips

For best results, ensure proper bolt-on installation to maintain the integrity of the bus connection and preserve protection performance. Confirm that the panelboard or load center is designed to accept the KDC3200Y’s 3-pole, 200A configuration and that wiring aligns with the device’s terminals. Regular inspection and torque checks (per manufacturer guidelines) help maintain a consistent, vibration-resistant connection over the long term.
