Siemens | 5SX2202-7 | Circuit Breaker | 2A | 2-Pole | 400V

Meet the Siemens 5SX2202-7 circuit breaker—a purpose-built protection device engineered for reliability in electrical panels. With a 2 A rated current, a 2-pole design, and a 400 V rating, this breaker provides precise, predictable protection for circuits that require careful current control and robust fault isolation.

Key specifications

• Amperage (rated current): 2 A
• Poles: 2-Pole
• Voltage rating: 400 V
• Part number: 5SX2202-7

Why this model matters

Designed for maintenance, retrofit, and replacement scenarios where exact compatibility is essential, the 5SX2202-7 delivers a reliable, drop-in protective solution when your panel is configured for Siemens’ 5SX series. The real value lies in ensuring correct trip characteristics and mounting compatibility by using the precise part reference.

Compatibility and fit

Important note: confirm fit and ratings before ordering. The 5SX2202-7 part number is the strongest reference for compatibility with your Siemens panel or enclosure. Verify that the mounting footprint, terminal configuration, and electrical characteristics align with your installation to avoid mismatches.

Ideal use cases

• Maintenance: replace aging or faulty breakers in existing Siemens systems with a like-for-like 2 A, 2-pole, 400 V unit.
• Retrofit: reconfigure panels where a 2-pole protection at 400 V and 2 A rating is required.
• Replacement: swap in for failed units that share the same 5SX2202-7 specifications to minimize downtime.

What you gain with Siemens 5SX2202-7

Choosing the exact part number reduces the risk of misfit components and ensures continuity of proper overcurrent protection. This breaker is ideal for controlled, low-current circuits where space efficiency matters, and where a precise 2-pole, 400 V solution keeps wiring organized and protection aligned with system design.
