Designed for maintenance, retrofit, and replacement projects, this two-pole bolt-on breaker provides a robust, secure fit where reliability matters most. Key specifications and what they mean for your installation

• Amperage: 350A – powerful protection for high‑demand feeders and critical circuits.
• Poles: 2‑Pole configuration – suitable for 2‑wire plus neutral protection in commercial and industrial panels.
• Voltage rating: 600V – designed for medium‑voltage residential/commercial/industrial panelboards and switchgear within this rating.
• Mounting: Bolt‑On – provides a secure, sturdy attachment for panels that require a bolt‑on installation method.
• Part reference: HHLXD62B350 – using the exact part number ensures accurate compatibility checks during sourcing.

Why this Siemens circuit breaker stands out - Precision fit for retrofit and replacement projects: When upgrading aging equipment or restoring protective device parity in a panel, matching the exact HHLXD62B350 part ensures electrical characteristics align with your system’s design and protection coordination. - Durable, maintenance‑friendly design: The bolt‑on mounting approach eases installation in field conditions where a reliable, vibration‑resistant connection is essential for long‑term performance. - Clear compatibility pathway: The part number is the best reference for ensuring your panelboard, switchgear, or enclosure will accept this unit without modification. Always confirm fit and ratings before ordering to avoid mismatches. Ideal use cases and scenarios - Upgrading legacy electrical panels to support 350A feeder circuits in manufacturing lines or processing units. - Retrofit projects where a direct 2‑pole, 600V protection device is required to maintain upstream protection coordination. - Replacement of worn or obsolete breakers in service entrances or control centers that demand a Siemens‑brand, bolt‑on 350A solution. Practical tips for installers and purchasing teams - Verify system compatibility by cross‑checking the exact part number (HHLXD62B350) against your panel’s catalog or service manual before ordering. - Plan for bolt‑on mounting space and hardware availability in the panel enclosure to ensure a seamless installation during maintenance windows. - Keep a record of the device’s amperage, pole count, and voltage rating in your asset management logs to simplify future replacements and audits. This Siemens circuit breaker is purposefully engineered for reliability in demanding environments, offering a precise 350A, 2‑pole, 600V bolt‑on solution that fits retrofit and replacement workflows with confidence.
