Square D | KHL3625021DC1680 | Circuit Breaker | 3-Pole | 600V

Meet the Square D KHL3625021DC1680 circuit breaker — a robust 3-pole, 600V protection device designed for maintenance, retrofit, and replacement projects where exact compatibility matters.

With the part number KHL3625021DC1680 serving as the primary reference, this unit fits Square D panels that share the same form factor and electrical characteristics. Always confirm fit and ratings before ordering to ensure uninterrupted protection and panel performance.

What makes this 3-pole, 600V breaker a smart choice

• Exact part reference for compatibility: KHL3625021DC1680 is the best starting point when matching replacement or retrofit parts to your existing Square D installation.
• Three-pole design: Delivers balanced protection across three conductors, ideal for 3-phase circuits and panel sections that require synchronized interruption.
• 600-volt rating: Suitable for commercial and light industrial applications where higher voltage protection is needed.
• Maintenance-friendly: A straightforward swap that minimizes panel downtime when replacing a failed or worn breaker.

Ideal use cases

Best suited for ongoing maintenance on legacy Square D panels, retrofit projects to restore protection in updated systems, or replacements in manufacturing floors, data centers, or large electrical rooms where a 3-pole breaker at 600V is the right fit.

How to ensure a precise fit

Before you order, cross-check the panel's model and the existing breaker to confirm that the three-pole, 600V configuration aligns with your bus arrangement and voltage needs. The part number is the most reliable reference for compatibility, reducing the risk of mismatch and downtime.
