Siemens 5SX22-D6 U 6A 2P 480V Contactor 2P 480V 6A

Siemens 5SX22-D6 U is a two-pole molded-case circuit breaker (MCCB) rated for 6 A and designed for 480 V AC installations. The 5SX22-D6 U model provides two main contacts and interrupts both poles together to protect branch circuits from overcurrent in 480 V distribution networks, making it suitable for use in commercial and light-industrial equipment enclosures, panels, and motor-control circuits that require compact, reliable protection. With a 6 A rating, it is intended for smaller load paths or control circuits within a larger electrical system, enabling selective coordination with higher-rated devices while providing fast, predictable tripping performance. The suffixes in the model naming denote the exact configuration for this device: 5SX22 indicates the two-pole version, D6 specifies the 6 A current rating, and U indicates a specific listing/variant in Siemens' catalog. When selecting this device, verify compatibility with your system voltage (up to 480 V AC) and ensure proper enclosure fit and terminal sizing for safe, code-compliant installation.
