ITE | P4320 | Circuit Breaker | 20A | 3-Pole | 240V

Introducing the ITE P4320 circuit breaker—a precise, dependable 20A, 3-pole, 240V protection solution designed for maintenance, retrofit, and replacement projects where exact compatibility matters. This ITE component is the ideal match for panels or distribution setups that require a three-pole interruption at a 240V rating, ensuring reliable shutdown and protection across all live conductors.

Key specifications

• Amperage: 20A
• Poles: 3-Pole
• Voltage rating: 240V
• Part number: P4320

Why this matters

In three-phase electrical systems, a 3-pole breaker like the P4320 provides synchronized protection for all phases, minimizing the risk of partial trips and equipment damage. The 20A rating is well-suited for common branch circuits and motor loads, delivering reliable overcurrent protection without compromising circuit performance. As an ITE-branded part, it’s engineered to align with compatible panels and accessories, helping you maintain a cohesive, safe electrical environment.

Use cases

• Maintenance or retrofit of existing panels that require P4320-compatible breakers
• Replacement for failed or worn 3-pole breakers in 240V circuits
• Panel upgrades where a precise 3-pole, 240V, 20A protection is necessary for balanced distributed loads

Compatibility and installation tips

Before ordering, confirm fit and ratings on your equipment—the part number is the most reliable reference for compatibility. If your setup specifies P4320 or a matching 3-pole 240V configuration, this breaker can serve as a direct replacement. Always follow your panel manufacturer’s guidelines for torque and mounting arrangements to ensure secure, safe operation.

What makes it stand out

Rather than a generic component, the ITE P4320 is a purpose-built solution for ITE-compatible systems, delivering dependable 3-pole protection at 240V with a clear, concrete part reference. This specificity helps you minimize compatibility risk and downtime during maintenance or upgrades, while still fitting neatly into standard panel layouts.
