Siemens HE43M015 15A 3-Pole 480 V Circuit Breaker

The Siemens HE43M015 circuit breaker is built for serious three-phase protection in industrial electrical systems. With a 15-amp rating and a 3-pole design, it provides synchronized disconnection across all phases at a 480 V supply, helping to safeguard wiring, motors, and downstream equipment from overcurrent faults.

• Current rating: 15 A
• Poles: 3
• Voltage rating: 480 V
• Part Number: HE43M015

Why this matters: In three-phase power environments, a fault on one leg can quickly affect the entire system. The HE43M015’s three-pole design ensures all phases trip together, reducing the risk of unbalanced currents and equipment damage. Born from Siemens’ trusted engineering, this breaker delivers dependable protection for distribution panels, motor drives, and industrial control circuits that rely on 480 V three-phase power. Ideal use scenarios:

• Protecting 480 V three-phase distribution circuits in factories, warehouses, and manufacturing lines
• Safeguarding motors, pumps, and conveyors in industrial automation setups
• Servicing Siemens-based electrical installations that require a precise 15 A, 3-pole protection solution

Practical considerations: - Designed to integrate within Siemens panel boards and compatible switchgear that support 480 V, 3-phase protection. - Use the Part Number HE43M015 to match replacement breakers for maintenance or upgrades. - When installing, ensure proper terminal torque and adherence to your panel’s wiring practices to maintain reliable fault interruption. This HE43M015 15 A, 3-Pole, 480 V circuit breaker from Siemens is a focused, reliable choice for protecting essential three-phase circuits. It combines targeted current rating, coherent three-pole operation, and a voltage specification aligned with industrial 480 V systems, helping you maintain safer, more reliable power distribution across demanding environments.
