Siemens | EH3A010 | Circuit Breaker | 10A | 3-Pole | 480V | Bolt-On

Meet the Siemens EH3A010 — a purpose-built circuit breaker designed for demanding electrical environments where precise protection and reliable service matter. This 3-pole, 10A device operates up to 480V and uses a bolt-on installation for secure, rapid fieldwork during maintenance or retrofits.

Key advantages that set the EH3A010 apart:

• Exact spec match for compatibility: Part number EH3A010 is the best reference for ensuring a correct fit in compatible panels and enclosures.
• Bolt-on convenience: A bolted mounting style simplifies installation and reduces vibration-related concerns in industrial settings.
• Three-phase protection: 3-pole design ensures balanced protection across all three conductors in 480V systems.
• Ideal for replacement, retrofit, and maintenance: Perfect when upgrading or substituting an existing breaker with matching amperage, pole count, and voltage.
• Operational readiness: Rated for use where 10A loads are managed with solid fault protection in zone distribution or control circuits.

Practical use cases:

• Replacing a worn-out breaker in a Siemens-based commercial or light-industrial panel that operates at 480V three-phase.
• Retrofits to bring older equipment up to current 3-pole 480V protection with a compact 10A rating.
• Maintenance cycles where fast bolted installation minimizes downtime and ensures consistent performance.

Important note: Before ordering, confirm fit and ratings for your specific panel or enclosure. The EH3A010's compatibility hinges on matching the part number with your system's specifications.
