Key specifications at a glance

• Current rating: 100 A
• Poles: 3
• Voltage rating: 600 V
• Part number: HHED63B100

Why this 3-pole design matters

In three-phase systems, a 3-pole breaker like the HHED63B100 simultaneously interrupts all live conductors. This coordinated trip minimizes equipment damage, reduces arc risks, and helps maintain safe shutdowns for motors, drives, and feeders. By protecting the entire three-phase circuit response, it supports longer equipment life and fewer unexpected outages.

Where it shines

• Industrial control panels and switchgear ensembles that rely on consistent three-phase protection
• Commercial HVAC, conveyors, and machinery that operate on 3-phase power
• Panelboards and distribution enclosures configured for Siemens protection devices

Unique value you get with Siemens HHED63B100

• Built to integrate smoothly with Siemens panels and protective systems, offering reliable trip characteristics and predictable performance
• Compact, durable construction that stands up to demanding environments while maintaining easy serviceability
• Clear part identification (HHED63B100) for fast maintenance, ordering, and documentation alignment

Practical considerations and best practices

To maximize protection and uptime, verify compatibility with your existing Siemens panels and labeling guidelines before installation. Use a licensed electrician for proper mounting, connection torque, and adherence to local electrical codes. Keep spare HHED63B100 units on hand for routine replacements or panel upgrades to minimize downtime.

Whether you’re upgrading an aging distribution system or equipping a new industrial installation, the Siemens HHED63B100 delivers dependable three-phase protection with a clear value proposition for 600 V applications. Its 100 A capacity ensures it can handle substantial loads while maintaining rapid, reliable tripping when faults occur.
