Overview
The Siemens 5SY4506-6 is a single-pole plus neutral (1P+N) miniature circuit breaker engineered for low-voltage industrial and residential distribution systems. Rated at 230V AC with 6A nominal current and Type B tripping characteristic, this SENTRON-series breaker delivers 10kA breaking capacity to protect circuits from overloads and faults. The compact DIN rail design ensures quick, tool-free installation.
Key Features
- 1P+N configuration: Single-pole protection with neutral continuity for split-phase or single-phase circuits
- Type B tripping: Trips at 3–5 times rated current; ideal for circuits with moderate inrush current such as resistive loads and long cable runs
- 10kA breaking capacity: Rated short-circuit protection per IEC 60898 industrial standards
- DIN rail mount: 18 mm top-hat rail mounting; 70 mm depth for compact panel layouts
- Tool-free removal: Slide-hand operation for fast disconnect from busbar or rail assembly
- Status indicator: Clearly visible switch position (ON/OFF) and data matrix code for quick identification
