Siemens | SPD69140 | Circuit Breaker | 3-Pole

Meet the Siemens SPD69140, a purpose-built 3-Pole circuit breaker designed for maintenance, retrofit, and replacement projects in three-phase electrical systems. Built to integrate seamlessly with compatible Siemens panels and distribution boards, this component helps keep your electrical infrastructure safe, reliable, and compliant.

Key details you can rely on

• Poles: 3-Pole — ideal for standard three-phase power networks in commercial, industrial, and many large-scale installations.
• Primary use: maintenance, retrofit, and replacement to restore or upgrade overcurrent protection without a full panel overhaul.
• Compatibility reference: The part number SPD69140 is the best guide for matching this breaker to your equipment.
• Important note: Confirm fit and ratings before ordering to ensure proper protection and electrical compliance.

Why choose SPD69140 for your project

As a Siemens original equipment component, the SPD69140 reflects the company’s commitment to dependable protection and long-term reliability. The 3-Pole design supports common three-phase configurations, delivering consistent interruption performance within compatible Siemens systems. This isn’t a generic replacement—it's a purpose-matched solution that aligns with your panel’s frame style and engineering intent, reducing the risk of compatibility issues and installation delays.

Ideal use cases

• Upgrading or replacing aging breakers in commercial or light industrial panels that run on three-phase power.
• Retrofit projects where maintaining Siemens compatibility is essential for system continuity and warranty considerations.
• Maintenance cycles that require a reliable, drop-in replacement to minimize downtime.

How SPD69140 stacks up against alternatives

Choosing a Siemens SPD69140 over generic or non-Siemens substitutes helps ensure a closer match to your existing protection scheme, reducing mismatches in trip characteristics, mounting foot prints, and electrical compatibility. It’s designed to align with Siemens’ design philosophy and installation practices, offering a smoother swap with fewer surprises during commissioning.

Practical tips for installation and verification

• Before ordering, verify that your panel or distribution board supports a 3-Pole breaker of the SPD69140’s frame type and rating.
• Use the SPD69140 part number as the primary reference when confirming compatibility with your equipment documentation.
• Ensure the replacement rating matches the circuit’s load and protection requirements, and follow all applicable safety guidelines during installation.
• After installation, perform standard testing procedures to confirm proper tripping behavior and electrical continuity.
