Siemens | EH3A005L | Circuit Breaker | 5A | 3-Pole | 480V

Meet the Siemens EH3A005L Circuit Breaker — a precise, rugged solution for 480V three‑phase systems that demands reliable protection in maintenance, retrofit, and replacement projects. Built to align with Siemens’ EH3A family, this 5A, 3‑pole unit delivers dependable performance where it matters most in industrial and commercial electrical environments.

Key specifications that matter

• Amperage: 5A
• Poles: 3‑Pole configuration for three‑phase feeds
• Voltage rating: 480V
• Part reference: EH3A005L — the go‑to compatibility anchor for matching components

Why this model stands out

• Direct compatibility with Siemens EH3A series systems. Using the exact part number EH3A005L helps ensure a seamless fit, preserving panel labeling and protective characteristics.
• Optimized for 480V industrial environments. The three‑pole design provides coordinated protection across all three phases, essential for balanced loads and safe operation of motors and feeders.
• Reliable replacement option. Designed for retrofit scenarios where uptime matters, letting you swap in a like‑for‑like control or distribution breaker without surprises.

Ideal use cases

• Maintenance and retrofit projects in industrial control panels that run on 480V three‑phase power.
• Replacement of worn or failed breakers in manufacturing lines, processing equipment, and large commercial systems.
• New installations that require a Siemens‑approved, 3‑pole 480V protection device with a 5A operating rating.

How it solves common problems

• Prevents nuisance trips by matching a precise 5A protective threshold for circuits routed through 480V feeders.
• Ensures compatibility with existing Siemens panels and EH3A‑based architectures, reducing guesswork during replacements.
• Streamlines procurement with a clearly defined part number—the EH3A005L—so you can reliably source the exact component you need.

Practical installation and care tips

• Before ordering, confirm fit and ratings against your panel labeling and the system’s voltage and series requirements. The part number EH3A005L is your best reference for compatibility.
• Keep in mind that this breaker is intended for 480V three‑phase circuits; ensure conductors, terminations, and protective devices in the panel are rated accordingly.
• When replacing a breaker, inspect associated wiring for wear or corrosion and verify torque specifications per your panel’s guidelines.

Whether you’re updating legacy equipment, performing scheduled maintenance, or equipping a new, Siemens‑driven control panel, the EH3A005L provides targeted protection with a precise fit for 480V three‑phase systems. Choose this model for a dependable, compatible solution that keeps your electrical infrastructure aligned with Siemens standards.
