Siemens | SLD69500 | Circuit Breaker | 500A | 3-Pole | 600V | 35kA

Protect your three-phase power distribution with precision using the Siemens SLD69500 circuit breaker. Engineered for reliability in maintenance, retrofit, and replacement scenarios, this unit delivers strong performance at 500 A with a robust 35 kA interrupting capacity, designed to safeguard your 600 V electrical systems.

Key specifications

• Amperage: 500 A
• Poles: 3-Pole
• Voltage rating: 600 V
• Interrupting capacity: 35 kA

What makes the SLD69500 stand out

When your installation relies on Siemens components, exact compatibility matters. The SLD69500 aligns with Siemens panels, switchgear, and protection schemes that require a 500 A, 3-pole device with a 35 kA fault-current rating. The part number itself—SLD69500—is the most reliable reference to ensure a perfect fit and consistent electrical characteristics across your system. This circuit breaker supports dependable operation, quick re-energization after a fault, and clear protection signals across all three phases.

Ideal use cases

• Direct replacement for aging Siemens protection devices in commercial or industrial facilities
• Retrofits to upgrade protection in existing power distribution panels and switchgear
• Protection for 3-phase, 600 V networks in manufacturing lines, data centers, and large mechanical rooms
• Situations where 500 A protection with a 35 kA interrupting capacity is required to meet system fault levels

How to ensure a proper fit

• Always confirm fit and ratings before ordering; use the part number SLD69500 as the primary reference for compatibility
• Verify that your system operates at up to 600 V and that the 35 kA interrupting capacity matches or exceeds your fault-current levels
• Have a qualified electrician perform installation or replacement, following all applicable safety standards and manufacturer instructions

Practical tips for reliable operation

Keep a spare on hand for planned maintenance windows to minimize downtime. Cross-check your panel labeling to ensure Siemens SLD-series compatibility, and align trip characteristics with your existing protection strategy to maintain consistent performance across your three-phase system.
