Product description
Shipping

Industrial-grade KS320300D circuit breaker delivers robust protection for 3‑phase systems with a 300‑amp rating. Designed for maintenance, retrofit, and replacement projects, this 3‑pole device helps you restore control while keeping your electrical infrastructure aligned with your existing specifications.

Key specifications at a glance

  • Amperage: 300A
  • Poles: 3‑Pole
  • Part number: KS320300D
  • Application: industrial circuit protection, suitable for maintenance, retrofit, and replacement where matching specs are required

Why this 3‑pole design matters

For three‑phase systems, a 3‑pole circuit breaker provides simultaneous disconnection of all phases, reducing the risk of partial power loss and protecting equipment from uneven loading. The KS320300D is built to align with standard industrial panels and feeders, helping maintain consistent protection across your system during upgrades or repairs.

Ideal use cases

  • Maintenance projects where a direct spec replacement is needed to minimize downtime
  • Retrofit initiatives that require matching amperage and three‑pole configuration
  • Replacement of aging breakers in industrial panels to restore reliable overcurrent protection

Compatibility and ordering guidance

Before purchasing, verify that the KS320300D matches your existing equipment’s ratings and mounting configuration. The part number KS320300D serves as the best reference for compatibility, helping you confirm fit with your panel or switchgear during procurement.

Installation and safety notes

Installation should be performed by qualified electrical professionals in accordance with local codes and manufacturer instructions. Ensure all power is isolated and equipment is de-energized before servicing, and follow proper torque and mounting procedures as dictated by your panel specifications.

What you gain with the KS320300D

  • Reliable overcurrent protection tailored for 3‑phase systems
  • Seamless maintenance and retrofit pathways with a definitive part reference
  • Clear compatibility guidance to reduce ordering guesswork and project delays
