R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103-C50-500-4
Art. Nr. 293905
Product Overview
The R. STAHL 8530/1-MCB-STA103-C50-500-4 miniature circuit breakers offer good current limitation for short circuits and high breaking capacity of 10, 15, or 25 kA. This results in lower stress on conductors and higher selectivity with upstream fuses. The modular design allows for 1- to 4-pole configurations and nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).
Key features include:
- Trennerfunktion according to EN 60947-2
- Energy limiting class 3
- Modular design for easy exchange or expansion
- Simple mounting by snapping onto top hat rails in Ex e enclosures
- Fixed thermal and magnetic trip units
- Ergonomically shaped operating lever for secure switching
- Provision for locking with padlocks (accessories) during maintenance
