ITE | HK3B120 | Circuit Breaker | 1200A | 3-Pole | 600V

Meet the ITE HK3B120 circuit breaker — a rugged, high-capacity solution engineered for demanding industrial power distributions. Designed for maintenance, retrofit, and replacement projects, this 3-pole device delivers reliable protection for 3‑phase systems operating at up to 600V.

• Amperage: 1200A
• Poles: 3-Pole
• Voltage rating: 600V
• Part reference: HK3B120
• Ideal use cases: maintenance, retrofit, and replacement in industrial electrical installations
• Important note: Confirm fit and ratings before ordering; the HK3B120 part number is the best reference for compatibility

This is more than a replacement part—it’s a purpose-built component that aligns with ITE panel configurations and three‑phase distribution systems. By selecting the HK3B120, you’re prioritizing compatibility, reducing installation guesswork, and preserving the integrity of your electrical infrastructure.

Who benefits most: maintenance teams refreshing aging panels, facilities undergoing retrofit to modernize power distribution, and engineers replacing worn breakers in 3‑phase, 600V environments. It’s particularly well-suited for manufacturing floors, large commercial installations, and service entrances where high‑current protection is essential.

Why choose this over generic substitutes: genuine ITE design ensures precise fit, mounting, and electrical characteristics that match your existing equipment. Using the exact part reference HK3B120 minimizes compatibility risk, speeds up replacement, and helps maintain consistent protection profiles across your distribution network.

Practical tips for deployment:

• Verify the breaker’s fit against your panel model and busbar spacing using the HK3B120 reference.
• Double-check system voltage (600V) and the 3‑phase configuration to ensure correct operation within your electrical layout.
• Keep spare HK3B120 units on hand for future maintenance cycles to minimize downtime.
