Square D | FIL360301021 | Circuit Breaker | 30A | 3-Pole | 600V

Meet the Square D FIL360301021 circuit breaker—an exact-fit, three-pole protective device engineered for demanding electrical environments. With a 30-amp rating and a 600V maximum, this unit is purpose-built for maintenance, retrofit, and replacement projects where reliable, predictable protection is non-negotiable. The part number FIL360301021 is your best reference for compatibility, and you should confirm fit and ratings before ordering to avoid surprises in the field.

Key specifications and what they mean

• Amperage: 30A — provides appropriate protection for mid-range three‑phase feeders and equipment without unnecessary nuisance tripping.
• Poles: 3‑Pole — essential for three‑phase systems, ensuring simultaneous disconnection across all phases for enhanced safety.
• Voltage rating: 600V — suitable for higher-voltage distribution panels and industrial applications, giving you robust protection where it’s needed most.

Why this exact part matters

The FIL360301021 designation guarantees a genuine Square D device designed to align with your panel’s geometry, trip characteristics, and bus interface. Choosing the correct part number minimizes compatibility risk, preserves protective coordination, and helps maintain system reliability across maintenance cycles, retrofits, and replacements.

Ideal use cases

• Retrofit projects in commercial or industrial facilities where a precise 3‑pole, 30A, 600V breaker is required to match existing protection schemes.
• Replacement for aging or failed breakers in modular or retrofit panels, restoring safe, consistent operation.
• New or upgraded three‑phase feeders that demand reliable, fast-acting interruption at 30A to prevent equipment damage and downtime.

Practical guidance for verification and installation

Before purchasing, check that your panel is labeled for a 3‑Pole, 30A, 600V device and that the frame and mounting style correspond to FIL360301021. The part number is the clearest indicator of compatibility—use it as your primary reference. For installation, engage a qualified electrician, ensure all power is isolated, and replace the old breaker with an identical or manufacturer-approved equivalent to maintain system integrity.

Additional advantages

Choosing this specific Square D unit delivers consistent performance in three‑phase systems, supports reliable protection for critical loads, and reduces the risk of mismatches that can lead to downtime. It’s a practical, purpose-built solution for professionals who value precision, compatibility, and long-term reliability in their protection schemes.
