Siemens HFG3B100L Circuit Breaker, 100A, 3-Pole, 600V

Engineered for demanding industrial environments, the Siemens HFG3B100L circuit breaker delivers dependable protection for three‑phase power systems up to 600 V. With a 100 A rating and a 3‑pole configuration, it safeguards heavy machinery, feeders, and panel installations across manufacturing, processing, and commercial facilities that rely on precise, reliable electrical protection.

Key compatibility starts with the part number. Use HFG3B100L to confirm a precise fit for your application and equipment. If you’re unsure about compatibility, send us a message and our team will help verify fitment and ensure a seamless replacement or upgrade.

• 3‑pole design for three‑phase systems
• 100 A to protect feeders and critical circuits
• 600 V to support industrial distribution and equipment
• ideal for industrial service, maintenance, and replacement projects; compatible with Siemens gear when the part number matches
• backed by Siemens engineering for consistent performance in harsh environments

Ideal use cases include main feeder protection in factory panels, replacement breakers in service panels and switchgear, motor control circuits in manufacturing lines, and panelboard upgrades where a three‑phase 100 A protection device is needed. This breaker is designed to integrate smoothly with existing Siemens equipment, helping you maintain system integrity and minimize downtime during service or retrofits.

Why choose this Siemens solution matters: a correctly matched, 3‑pole 100 A breaker for 600 V systems reduces the risk of nuisance trips while providing dependable interruption capability when faults occur. It’s a practical, long‑term investment for facilities aiming to keep electrical distributions safe and compliant.

To ensure a precise fit, verify the part number against your panel or switchgear requirements and review your application needs (3‑phase load, fault protection strategy, and service voltage).
