Built for reliability in maintenance, retrofit, and replacement projects, this breaker helps you safeguard critical electrical infrastructure with precise, code-compliant performance.

• Amperage: 70A
• Poles: 2-Pole
• Voltage: 480V
• Mounting: Bolt-On
• Part Reference: HE2A070
• Typical Uses: maintenance, retrofit, and replacement to match exact specifications

Why choose the HE2A070 for your installation

The HE2A070 is engineered for dependable protection in environments where 480V circuits require solid, secure isolation. Its bolt-on design provides a rugged, vibration-resistant connection that stays put in demanding panel layouts, making it a practical choice for retrofit projects and legacy system upgrades.

Ideal use scenarios

• Upgrading aging panels in warehouses, manufacturing plants, or data centers where 480V distribution is standard
• Replacement in systems that require exact amperage and pole configuration to maintain protection coordination
• Maintenance cycles where downtime needs to be minimized and compatibility is critical

How to verify a correct fit

To ensure compatibility, rely on the part number HE2A070 as the primary reference. Before ordering, confirm:

• The panel or enclosure supports bolt-on 2-pole breakers
• The circuit is configured for 480V operation and 70A protection
• Your installation requires a direct replacement with the same amperage, pole count, and mounting method

Practical considerations for installation and use

Because this breaker is designed for bolt-on mounting, prepare for secure, space-efficient installation in compatible panels. Keep in mind that fit and ratings must be validated for each specific application; the part number HE2A070 is the most reliable reference to ensure you match the exact Siemens specification and performance expectations.
