KS320350D | Circuit Breaker | 350A | 3-Pole | 240V

Meet KS320350D, an industrial-grade circuit breaker engineered to deliver reliable overcurrent protection in demanding power systems. With a commanding 350A rating, a 3-pole configuration, and 240V nominal operation, this device is built for durability in maintenance, retrofit, and replacement projects where exact specs matter.

Precise, compatible performance

Designed as a direct-fit component for compatible panels and switchgear, the KS320350D shines when you need a predictable, easy-to-match solution. Its identity by part number makes compatibility checks straightforward, reducing the guesswork that can slow down critical downtime and project timelines.

• Amperage: 350A — robust protection for high-load circuits in industrial environments.
• Poles: 3-Pole — three-phase protection with coordinated disconnect to preserve system balance.
• Voltage: 240V — suitable for standard industrial three-phase distribution and control circuits.
• Reference: KS320350D — using the exact part number ensures the best compatibility reference for replacements and retrofits.

Where and how it shines

Ideal for maintenance, retrofit, and replacement scenarios in factories, warehouses, and other heavy-duty facilities, this breaker protects motors, conveyors, and critical distribution lines. If your existing panel uses a 350A, 3-pole, 240V device, KS320350D offers a precise match that helps you maintain protective coordination and consistent performance across your electrical system.

Choosing a part-number–driven replacement matters: it minimizes compatibility risks and preserves the intended trip characteristics and protection philosophy of your installation, so you stay in compliance with safety standards and electrical codes.

Practical tips for a smooth upgrade

Before ordering, verify fit and ratings against your panel documentation. The KS320350D is the best compatibility reference—if your system lists this exact part, you’re aligned with the manufacturer’s protection scheme. For installation, plan a safe, de-energized replacement following your facility’s lockout/tagout protocols, and check that the enclosure, mounting, and terminations match your existing hardware.

Who benefits most

Engineers, maintenance managers, and technicians responsible for industrial power distribution will appreciate a dependable, exact-match component that reduces downtime and ensures consistent protection across three-phase systems.

Why this unit stands out

Beyond its specs, KS320350D emphasizes precise compatibility through its dedicated part-number reference, helping you avoid misfits and mismatched protection schemes. In environments where reliability and uptime are non-negotiable, this 350A, 3-pole, 240V circuit breaker delivers the clarity and confidence you need for steady, safe operation.
