Siemens | HE3B035 | Circuit Breaker | 35A | 3-Pole | 480V

Siemens engineers this HE3B035 circuit breaker to deliver reliable protection for 480V three-phase electrical systems. Built for maintenance, retrofit, and replacement projects, this 3-pole unit ensures coordinated isolation of all phases, reducing risk during service and delivering consistent outage protection where you need it most.

Key specifications

• Amperage: 35A
• Poles: 3-Pole
• Voltage: 480V

Important note: confirm fit and ratings before ordering. The HE3B035 part number is the most reliable reference for compatibility with your equipment. When selecting a replacement or retrofit part, verify that your panel enclosure, bus configuration, and required interrupting rating align with this unit to maintain code compliance and optimal protection.

This 3-pole design is particularly well-suited for three-phase distribution networks where balanced protection across all phases is essential. By disconnecting all poles simultaneously in fault or maintenance scenarios, it simplifies service procedures and minimizes the risk of partial energization that can occur with single- or two-pole solutions.

Ideal use cases

• Replacing a damaged or aging breaker in 480V, three-phase panels
• Retrofits in industrial controls, manufacturing lines, or HVAC distributions that rely on stable 3-phase protection
• Spare part for facilities that standardize on Siemens HE-series components to streamline maintenance

Why choose the Siemens HE3B035 in particular? It’s designed to match Siemens’ trusted specification standards, offering predictable tripping behavior and dependable performance within 480V three-phase systems. If you’re coordinating a retrofit or stocking parts for ongoing service, this specific 35A, 3-pole unit provides a precise, compatible fit that minimizes guesswork and downtime.

Practical tip: when replacing, inspect the surrounding hardware—terminal screws, bus bars, and mounting kit compatibility—to ensure a seamless installation. Keeping a spare HE3B035 on hand can shorten outages and keep critical equipment running smoothly, especially in facilities where 480V three-phase power is a backbone of operation.
