Square D | KCL34110 | Circuit Breaker | 110A | 3-Pole | 480V

Square D KCL34110 Circuit Breaker is a rugged three-pole, 110-amp device designed for 480V, three-phase electrical systems. Built for reliability in demanding industrial environments, this breaker integrates with compatible Square D panels and enclosures to protect critical equipment and processes.

Features at a glance:

• Amperage: 110A — provides decisive overcurrent protection without nuisance trips in steady, high-load applications.
• Pole configuration: 3-Pole — ideal for standard 3-phase distribution and panelboards.
• Voltage rating: 480V — suitable for medium-voltage distribution common in manufacturing, data centers, and large facilities.
• Part number reference: KCL34110 — the most reliable cross-reference for compatibility with Square D products.

Why this Square D breaker stands out:

• Direct fit for maintenance, retrofit, and replacement when your panel labeling or legacy breakers indicate KCL34110 compatibility.
• Consistent performance across temperature variations and continuous-duty environments often found in industrial settings.
• Backed by Square D’s reputation for durable construction and predictable trip characteristics, helping you maintain uptime and safety.

How to verify compatibility before ordering:

• Check your panel’s label and cross-reference the part number to KCL34110 to ensure a precise match.
• Confirm the system voltage is 480V and that your installation requires a 3-pole breaker for a 3-phase circuit.
• Ensure the enclosure type and bus stabs align with Square D replacement breakers to avoid fitment issues.

Practical use scenarios:

• Maintenance shutdowns in manufacturing lines where a 3-phase, 480V feed must be reliably interrupted during service.
• Retrofit projects upgrading legacy equipment to a modern, code-compliant protection device with clear part-number traceability.
• Spare part for industrial facilities that standardize on Square D components to streamline inventory and repair workflows.

Note: Always power down and follow local electrical codes during installation. If you’re unsure about compatibility, use the part number KCL34110 as your reference point and consult your panel’s documentation.
