Key specifications

• Amperage: 15A
• Poles: 3-Pole
• Voltage: 480V
• Mounting: Bolt-On
• Part number: EH3A015L

Why choose this Siemens bolt-on breaker?

• Designed for three-phase circuits up to 480V, making it ideal for equipment, MCCs, and control panels that rely on reliable 3-pole protection at medium voltage levels.
• Secure bolt-on mounting: The bolt-on design ensures a robust, vibration-resistant connection that’s well-suited for industrial enclosures and retrofit installations where plug-on variants aren’t suitable.
• Pertinent for upgrades and replacements: When upgrading legacy systems or replacing worn components, matching the EH3A015L’s amperage, pole count, and voltage minimizes downtime and preserves protective coordination in your panel.
• Clear compatibility guidance: The part number is your best reference—always verify fit and ratings before ordering to avoid mismatches in panel frames, bus configurations, or trip characteristics.

Use cases and ideal applications

• Upgrading or replacing circuit protection in industrial control panels, motor control centers, or electrical distribution gear operating at 480V three-phase systems.
• Retrofit projects where existing equipment relies on bolt-on breakers for secure mounting and straightforward service access.
• Maintenance cycles that require precise, repeatable protection ratings to maintain system reliability and safety margins.

Installation and compatibility tips

• Verify fit first: Confirm that your panel accepts bolt-on breakers and that the EH3A015L matches your current configuration and ratings.
• Cross-reference guidance: Rely on the part number as the primary compatibility reference to align with bus bars, mounting hardware, and enclosure design.
• Plan for safe service: Ensure proper de-energization, follow safety protocols, and check the panel’s frame and bus geometry before replacing or installing the unit.

Whether you’re conducting routine maintenance, performing a controlled retrofit, or replacing a worn-out breaker in a 480V three-phase system, the Siemens EH3A015L bolt-on circuit breaker delivers targeted protection with dependable performance.
