Siemens QJ3B200L is a purpose-built 200A, 3-pole circuit breaker designed for reliable protection in 240V, 3-phase electrical environments. Built to support maintenance, retrofit, and replacement projects, this unit helps you keep critical power systems safe and up to spec when matching the exact part number is essential.
- Amperage: 200A
- Poles: 3-Pole
- Voltage: 240V
- Reference: Part number QJ3B200L is the best compatibility marker
Why choose the QJ3B200L for your panel? When your setup demands precise fit and ratings, this Siemens breaker provides the dependable protection you need for 3‑phase feeders and distribution circuits. It’s especially valuable in retrofit projects or when replacing a failed unit in existing Siemens panels that specify the QJ3B family. The exact part number ensures you’re selecting a device that matches the electrical characteristics and mounting geometry required by your equipment, reducing downtime and compatibility risk.
Use cases and practical applications
Ideal for routine maintenance scheduling in commercial or light industrial panels, this breaker supports:
- Replacing a worn or failed 3‑pole, 200A breaker in a 240V 3‑phase distribution system
- Retrofits where a 200A main or feeder protection is needed without changing panel hardware
- Upgrading aging shutdown protection to restore reliable circuit control and isolate faults quickly
Before ordering, verify fit and ratings against your equipment’s documentation. The part number QJ3B200L serves as the most reliable compatibility reference, ensuring that dimensions, clip/slide mounting, and electrical characteristics align with your Siemens panel and 3‑phase configuration.
Practical tip: keep a compatible spare on hand for planned maintenance or unexpected outages. When in doubt, cross-check the service panel’s label or documentation for the QJ3B family requirements to minimize installation surprises and maximize system uptime.
Elevate your panel protection with the Siemens QJ3B200L—precise, dependable, and designed to meet the exact specs your 3‑phase 240V system demands.
