Overview
The Siemens 5SX22 C1 miniature circuit breaker is a single-pole, 1-ampere MCB designed for general-purpose electrical distribution and protection applications. Built to IEC/UL1077 standards, this DIN rail–mounted breaker provides thermal-magnetic trip protection against overloads and short circuits, making it suitable for control circuits, auxiliary power, and light-load applications in industrial and commercial environments.
Key Features
- 1-ampere rated current with Type C trip characteristic (5–10 In instantaneous trip)
- Single-pole (1P) configuration for individual circuit protection
- DIN rail mount for standard 35 mm rail installation
- Thermal-magnetic tripping mechanism ensures fast disconnection under fault conditions
- Compact form factor suitable for crowded electrical panels
- IEC/UL1077 certified for international safety compliance
