Siemens | ED42B080L | Circuit Breaker | 80A | 2-Pole | 480V

Siemens ED42B080L circuit breaker — an 80-amp, two-pole device designed for 480V distributions. Crafted for maintenance, retrofit, and replacement projects, this breaker ensures exact spec alignment so your electrical system stays protected without guesswork.

Key specifications

• Amperage: 80A
• Poles: 2-Pole
• Voltage: 480V
• Reference/Part number: ED42B080L

Important note: Confirm fit and ratings before ordering. The ED42B080L part number is the best reference for compatibility.

Why this Siemens breaker stands out

Rather than generic substitutes, the ED42B080L delivers a precise match for systems requiring an 80A, 2-pole, 480V protection device. The two-pole design ensures simultaneous disconnection of both hot legs, enhancing safety and maintaining the integrity of your distribution network. By sticking to the exact part number, you minimize the risk of incompatibility and ensure consistent performance across your 480V infrastructure.

Ideal use cases

• Maintenance and service upgrades in commercial and industrial panels operating at 480V.
• Retrofit projects where existing equipment demands an 80A, 2-pole device with matching electrical characteristics.
• Replacement scenarios to restore original protection profiles after component wear or panel refreshes.

Practical guidance for planning and installation

• Verify the panel’s compatibility and ensure the ED42B080L aligns with your system’s voltage and current requirements.
• Keep a spare ED42B080L on hand as part of your maintenance strategy to minimize downtime.
• Store surplus breakers in a cool, dry environment to preserve insulation and reliability.
