Siemens | SND69800A | Circuit Breaker | 800A | 3-Pole | 600V | 35kA | Bolt-On

Meet Siemens SND69800A — a rugged, bolt-on circuit breaker built for demanding power distribution environments. With a rating of 800A across three poles, it delivers reliable protection for high-load feeders in industrial and commercial settings. Rated for 600V, it handles significant fault currents with a 35kA interrupting capacity, helping minimize damage during short-circuits.

Designed for maintenance, retrofit, and replacement projects, this 3-pole breaker fits compatible Siemens switchgear and panel enclosures that support bolt-on mounting. The part number SND69800A serves as your best reference for compatibility, so double-check fit and ratings before ordering.

Key features

• Current rating: 800A
• Poles: 3-Pole configuration for three-phase protection
• Nominal voltage: 600V
• Interrupting capacity: 35kA short-circuit withstand at 600V
• Mounting: Bolt-On for secure, quick installation in compatible panels
• Reference: Siemens part number SND69800A

Use cases and benefits:

• Upgrading a high-load feeder in an industrial facility or data center where reliable three-phase protection is critical
• Retrofits to modernize legacy switchgear without replacing entire panels
• Repairs after a fault to restore service quickly while ensuring aligned ratings and compatibility
• Maintenance shutdowns requiring a like-for-like replacement with the exact amperage, voltage, and interrupting capacity

Why choose this Siemens breaker over alternatives? Its higher interrupting rating (35kA) at 600V supports stronger fault protection, reducing arc flash risk and equipment damage. The bolt-on design streamlines installation in target Siemens assemblies, helping minimize downtime during retrofits and replacements and ensuring a secure, code-compliant fit.

Practical tips for installation and selection:

• Always verify that your panel or switchgear supports bolt-on breakers in the SND family and that the amperage and voltage ratings align with your distribution needs.
• Keep the exact part number handy (SND69800A) to avoid compatibility gaps during orders or spare parts procurement.
• When planning a retrofit, map out feeders and protection coordination to ensure the new breaker settings match upstream devices.

For professionals managing electrical distribution, the Siemens SND69800A represents a precise, compatible, and dependable option for restoring capacity and safeguarding equipment in demanding environments.
