R. STAHL LS Miniature Circuit Breaker 8530/1-MCB-STA103-C32-500-4
Article No.: 293903
Product Overview
The R. STAHL 8530/1-MCB-STA103-C32-500-4 is an LS Miniature Circuit Breaker designed for robust performance and safety. It offers good short-circuit current limitation and high switching capacity of 10, 15, or 25 kA, ensuring minimal load on lines and high selectivity with upstream fuses. The modular design allows for 1- to 4-pole configurations and nominal currents from 0.5–63 A, with a maximum installation capacity of 4.5 module widths (TE).
- Trennerfunktion (Isolating function): according to EN 60947-2
- Energiebegrenzungsklasse (Energy Limiting Class): 3
- Modular Design: Enables simple replacement or expansion of installations.
- Easy Installation: Snap-on mounting onto top-hat rails in Ex e enclosures.
- Fixed Thermal and Magnetic Trip Units
- Ergonomic Actuating Lever: Ensures secure switching on and off.
- Padlockable: For protection against unintentional re-engagement during maintenance (accessory required).
