KD3150 | Circuit Breaker | 150A | 3-Pole | 600V | 35kA | Feed-Through

Meet KD3150, a rugged industrial circuit breaker engineered for reliable 3-phase protection with feed-through capabilities. Designed for 150A service envelopes, this 3-pole unit delivers precise coordination across all phases while handling demanding 600V systems. It’s the dependable choice for maintenance, retrofit, and replacement projects where exact compatibility matters.

With a robust 35kA interrupting capacity, KD3150 provides solid protection against high fault currents, keeping downstream equipment and personnel safer in challenging industrial environments. The feed-through design enables clean downstream distribution, allowing you to feed sub-panels or additional circuits without sacrificing the main protection you rely on.

Key benefits

• Feed-through configuration: streamlined downstream distribution through integrated lugs, reducing complexity and additional components.
• Three-pole protection: synchronized tripping across all phases for balanced, reliable shutdown in 3-phase systems.
• 600V rating: suitable for a wide range of industrial equipment, motors, and control circuits.
• High fault-current capacity: 35kA interrupting capability to handle demanding electrical environments.
• Precise compatibility reference: part number KD3150 is the best reference for matching replacements and retrofits.

Ideal use cases

• Maintenance and retrofit projects where exact 150A, 3-pole, 600V protection is required.
• Upgrading or replacing aging breakers in industrial panelboards and switchgear with feed-through needs.
• New installations that demand straightforward downstream distribution to sub-panels without adding extra lugs or components.
• Spare parts strategy for facilities with standardized KD3150 units to minimize misfits and downtime.

Compatibility and installation notes

Before ordering, confirm fit and ratings against your current panel or switchgear configuration. The KD3150 is best matched by its part number to ensure correct bus arrangement and lug compatibility. This is a feed-through breaker—plan for downstream connections and verify that the panel supports a 3-pole, 600V, 150A unit with the appropriate interrupting capacity. Adhere to standard electrical safety practices during installation and servicing to maintain a safe, compliant electrical system.

Whether you’re performing routine maintenance, upgrading an existing installation, or expanding your distribution network, the KD3150 delivers precise, reliable protection with a practical feed-through solution tailored for industrial environments.
