LAB3125 | Circuit Breaker | 125A | 3-Pole | 600V

Meet LAB3125, a rugged industrial circuit breaker designed for reliable protection in 3‑phase systems. With a 125A rating and 3‑pole configuration, this unit is built to handle demanding maintenance, retrofit, and replacement tasks where exact specifications matter. It’s the smart choice when your goal is to maintain safe, uninterrupted power delivery in commercial or light industrial environments operating up to 600V.

• Exact spec compatibility: The LAB3125 part number is your most reliable reference for matching panels, switchgear, and assemblies. Always verify fit and ratings against your equipment label before ordering.
• Three-phase protection: A true 3‑pole design ensures simultaneous interruption across all phases, helping to prevent load imbalances and protecting motors, drives, and downstream circuits.
• High-current capability: 125A continuous rating accommodates a wide range of load profiles while aligning with upstream protection schemes for coordinated tripping.
• 600V readiness: Suitable for circuits in typical industrial distribution and motor-control applications, providing solid performance in demanding environments.
• Maintenance-friendly replacement: Designed for straightforward swap‑outs in existing systems, reducing downtime during retrofits or panel upgrades.

Ideal for

• Electrical contractors performing panel retrofits or replacements in commercial facilities
• Maintenance technicians upgrading aging electrical distribution or motor-control panels
• Industrial plants replacing worn breakers while maintaining the same 3‑phase protection scheme

Why this matters

Choosing the exact LAB3125 part eliminates guesswork when restoring protective relays and breakers in your gear. By sticking to the specified 125A, 3‑pole, 600V ratings, you preserve protection coordination, minimize the risk of nuisance trips, and keep your electrical system compliant with existing designs. This isn’t a generic substitute — it’s the targeted choice that aligns with your installation’s design intent and legacy components.

Practical setup tips: Have your panel labeling or service documentation handy to confirm the LAB3125 matches your required trip characteristics and termination style. If you’re replacing an older unit, inspect the surrounding wiring and mounting pattern to ensure a seamless fit and secure termination.
