Square D | LAL361751021 | Circuit Breaker | 175A | 3-Pole | 600V

Meet the Square D LAL361751021 Circuit Breaker — a precision 175A, 3-pole, 600V protective device designed for maintenance, retrofit, and replacement projects where exact compatibility matters. Built to integrate with existing Square D panels that rely on the LAL style, this breaker delivers reliable three-phase protection in a compact footprint.

• Amperage: 175 A — provides robust protection for medium-to-large 3‑phase feeders without unnecessary trips.
• Poles: 3-Pole — ideal for three‑phase power distribution and motor circuits, ensuring simultaneous shutdown across all phases.
• Voltage rating: 600V — suitable for a wide range of industrial distribution schemes and higher-voltage panels.
• Part reference: LAL361751021 — using the exact part number helps guarantee fit with your existing panel footprint and bus arrangement.

Why this matters for your project:

• Accurate retrofit or replacement: When a breaker fails or you’re upgrading a panel, matching the part number LAL361751021 ensures proper alignment, Contacts, and mounting compatibility.
• Three‑phase protection made straightforward: A 3-pole device ensures all lines trip together, preventing unbalanced conditions that could damage equipment.
• Versatile for industrial settings: The 600V rating accommodates diverse distribution schemes from machine controls to line feeders.

Ideal use cases:

• Replacing a failed breaker in an existing Square D panel that uses the LAL series
• Upgrading feeders to support higher amperage on a 3‑phase motor or processing line
• Retrofit projects where the panel specification calls for a 3‑pole, 600V protection device with a 175A rating

Practical tips for a smooth install:

• Double-check fit and ratings against your panel documentation before ordering—LAL361751021 is the best reference for compatibility.
• Power down the main disconnect and follow manufacturer safety practices during replacement.
• Keep the panel’s wiring diagram handy to verify correct bus and terminal connections for this breaker’s footprint.

In short, the Square D LAL361751021 circuit breaker delivers dependable, three‑phase protection in a 175A, 3‑pole, 600V package, tailored for maintenance, retrofit, and replacement tasks where exact compatibility and performance matter most.
