Eaton EHD3100V 100A 3-Pole 3100 V Circuit Breaker

Eaton EHD3100V 100A 3-Pole 3100 V Circuit Breaker provides dependable overcurrent protection for demanding high-voltage electrical installations. Designed for industrial power systems, this part (EHD3100V) ensures robust, reliable performance when safeguarding feeders, switchgear, and heavy-duty machinery in environments where voltage and current demands are high.

Key specifications at a glance

• Current rating: 100 A
• Pole configuration: 3-pole
• Voltage rating: 3100 V

Why this 3-pole design matters

With a true three-phase configuration, the Eaton EHD3100V trips all poles simultaneously to isolate faults quickly and safely. This coordinated disconnection minimizes phase imbalance, protects downstream equipment, and reduces the risk of damage during short circuits or overloads. The result is steadier operations, less downtime, and a safer shutdown sequence for your high-voltage power distribution network.

Ideal use cases

• High-voltage feeders in industrial facilities and manufacturing lines
• Protection for switchgear assemblies and large electrical rooms
• Feeder protection for transformers, motors, and HVAC systems operating at up to 3100 V

What makes this breaker stand out

Unlike lower-voltage or smaller-profile breakers, the EHD3100V is purpose-built for high-voltage environments, combining Eaton’s proven reliability with a configuration that supports clean, safe fault isolation across three phases. The part number EHD3100V also ensures straightforward procurement and compatibility within Eaton’s ecosystem, simplifying replacements and maintenance planning in complex electrical setups.

Practical considerations and best practices

• Verify compatibility with your panel, bus arrangement, and enclosure before installation.
• Ensure adherence to local electrical codes and safety standards during replacement or servicing.
• Engage a qualified electrician to perform installation and verify proper mounting and electrical connections.
