Siemens EH3M015 15A 3-Pole 480 V Circuit Breaker

Engineered by Siemens, the EH3M015 15A 3-Pole 480 V Circuit Breaker delivers precise, reliable protection for 3-phase power distribution in demanding environments. Built to handle industrial loads, this molded-case breaker is designed to interrupt fault currents quickly while staying compact enough to fit in standard switchgear and control panels.

• Current rating: 15 A; Poles: 3; Voltage rating: 480 V — ideal for protecting three-phase circuits and equipment in industrial facilities.
• Three-pole design provides synchronized interruption across all phases, helping prevent phase-to-phase faults and equipment damage.
• Part Number EH3M015 ensures compatibility with Siemens panels and compatible enclosures, simplifying replacement and stocking.
• Durable construction supports long service life in demanding environments, with dependable performance in data centers, manufacturing lines, and HVAC systems.
• Simple installation and clear labeling make routine maintenance and troubleshooting faster, reducing downtime.

Use cases and scenarios:

• Feeding three-phase motors and drives in manufacturing lines where 480 V is the distribution standard.
• Protecting feeders in industrial control panels, switchboards, and power distribution units that rely on 480 V three-phase power.
• Replacing worn or obsolete breakers in Siemens-compatible panels, with a straightforward swap to EH3M015 for continuity of protection.

Why choose this Siemens circuit breaker over alternatives? It combines a known Siemens engineering standard with a precise 15 A rating and a robust 3-pole, 480 V capability that aligns with common industrial electrical architectures. That means predictable trip behavior, easier panel planning, and a straightforward maintenance path for facilities already stocked with Siemens components.
