Siemens 5SX2104-7 Circuit Breaker, 4A, 1-Pole, 400V

Siemens 5SX2104-7 circuit breaker is built for rugged industrial electrical service, maintenance, and replacement projects. This 4 A, 1-pole device protects a single hot conductor in 400 V systems, delivering dependable overcurrent protection for critical equipment and control circuits.

Key benefits and uses:

• Precise single-pole protection for 400V industrial panels: keeps wiring and equipment safe in environments where a dedicated 1-pole breaker is required for single-phase feeders or control circuits.
• 4 amp rating, ready for light-to-moderate loads: a precise current threshold that minimizes nuisance trips while safeguarding circuits.
• Part number 5SX2104-7 ensures compatibility: use the exact Siemens part number to confirm fit for your application—critical for compliant panel upgrades or replacements.
• Industrial-grade reliability: designed to meet the demands of service crews and maintenance schedules in manufacturing and facilities environments.
• Simple, fast replacement: standard form and footprint help you swap in seconds during downtime events.

Practical use cases:

• Replacing a worn or failed breaker in Siemens panels within 400V electrical distributions.
• Stocking a ready-to-go spare for maintenance shifts to minimize downtime.
• Upgrading older installations to a current Siemens part to maintain system safety and compliance.
