• Part number: EH3B025

Why the EH3B025 Stands Out

This circuit breaker is purpose-built for environments where dependable three-phase protection is non-negotiable. The bolt-on design simplifies installation in compatible panels, providing a secure, durable connection that stays put in industrial settings. With a 25A rating at 480V, it’s suited to protect feeders, motors, and other critical loads in manufacturing, processing, and large commercial facilities.

Ideal Use Cases

• Maintenance and upgrades of existing 3-phase panels requiring a 25A, 480V bolt-on breaker
• Retrofits in legacy systems that rely on bolt-on protection devices for reliable service
• Replacement for aging breakers in industrial equipment and distribution panels

Compatibility and Installation Tips

• Use the part number EH3B025 as the primary reference to confirm compatibility with your panel and bus arrangement.
• Before ordering, verify that your equipment supports a 3-pole, 480V bolt-on breaker and that the mounting footprint matches your panel.
• Plan for secure mounting and proper electrical connections according to your panel’s installation guidelines.

Designed for professionals who demand precision and reliability in industrial power protection, the Siemens EH3B025 delivers targeted performance for maintenance, retrofit, and replacement projects. If your system matches these specifications, this bolt-on breaker offers a straightforward, dependable solution built to sustain demanding operations.
