Siemens 5SX22-D6 - 6A, 400VAC, 2-Pole, Circuit Breaker

Siemens 5SX22-D6: 6A, 400VAC, 2-Pole Circuit Breaker

The Siemens 5SX22-D6 delivers dependable overcurrent protection in a compact, two-pole package designed for demanding industrial environments. Rated for 6A up to 400VAC, this breaker provides robust protection for feeders, branch circuits, and motor control centers while simplifying coordination in complex electrical assemblies.

• Current rating: 6A
• Voltage rating: 400VAC
• Poles: 2-Pole
• Breaker type: Circuit Breaker
• Applications: panelboards, switchboards, control panels, and motor control centers

Why choose the 5SX22-D6? The two-pole design ensures simultaneous disconnection of both conductors, enhancing safety and arc control during fault conditions. Built for industrial and commercial use, it provides reliable protection where uptime matters—whether you’re wiring a new distribution panel, upgrading an OEM control system, or stocking spares for ongoing maintenance in a factory MCC.

Ideal use cases

• Feeder protection in distribution panels and switchboards for manufacturing lines
• Protection of control circuits feeding programmable logic controllers and drives in OEM installations
• Motor control center protection where coordinated disconnection improves safety and downtime avoidance
• Replacement part for Siemens-based installations, ensuring compatibility and easy procurement

Practical considerations for installation

• Confirm 400VAC system voltage and ensure the circuit breaker is configured for 2-pole protection
• Plan wiring to maximize the benefits of simultaneous pole disconnection and streamlined routing in panels
• When integrating with existing Siemens infrastructure, align with standard panel and MCC mounting practices for straightforward installation

From factory floors to critical control rooms, the Siemens 5SX22-D6 brings precise, reliable protection where it’s most needed. It’s the practical choice for professionals who demand consistent performance, easy maintenance, and seamless compatibility within Siemens-distributed electrical systems.
