ITE HE3B020: 20A 3-Pole 600V Bolt-On Circuit Breaker

Designed for reliability in demanding electrical distributions, the HE3B020 is a 3-pole circuit breaker rated for 20 amps per pole and a maximum of 600V. This bolt-on device is ideal for maintenance, retrofit, and replacement projects where exact specifications matter and a secure, rugged mounting is essential.

Key features that matter in the field

• Triple‑pole protection: 3‑pole design provides coordinated protection across all three phases, helping prevent unbalanced loads and ensuring a clean, simultaneous shutdown when needed.
• 600V maximum voltage: Built to handle common industrial distribution environments, keeping your system protected under higher voltage conditions.
• 20A rating per pole: Balances typical load requirements with dependable overcurrent protection for each phase.
• Bolt-On mounting: Quick, secure installation that maintains a solid connection in fixed enclosures, reducing the risk of loose contacts and vibration over time.
• Legacy and retrofit‑ready: Common in panels designed for ITE equipment; the part number HE3B020 is the best reference for compatibility.

Why this breaker is a smart choice for your panel upgrade or replacement

When upgrading or servicing a panel, matching the exact part is crucial to maintain electrical integrity and minimize downtime. The HE3B020 aligns with original design intent, delivering reliable protection without the need for panel redesign. Its bolt-on construction provides a robust mechanical interface, making it a dependable choice in control rooms, manufacturing floors, and service panels where space is tight and vibration is a factor.

Practical use cases

• Replacement in legacy ITE installations requiring a 3-pole 600V breaker with a 20A rating.
• Retrofit projects in industrial equipment where precise, multi‑phase protection is essential for multiple feeders.
• Maintenance swaps in panels to restore original protection levels quickly and accurately.

What to verify before ordering

• Match the exact part number: HE3B020.
• Confirm amperage (20A per pole) and a 3-pole configuration match your panel’s rating.
• Ensure bolt-on mounting is compatible with your enclosure’s bus bar arrangement and space constraints.
• Verify your system voltage is within the 600V rating.
