R. STAHL LS Miniature Circuit Breaker 8530/1-MCB-STA103N-B63-000-4
Art. Nr. 293852
Product Overview
The R. STAHL LS Miniature Circuit Breakers of the 8530 series offer good current limitation for short circuits and high switching capacity of 10, 15, or 25 kA. This results in reduced stress on the lines and higher selectivity to upstream fuses. The modules are designed for modularity and are available in 1- to 4-pole versions for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).
Key features include:
- Disconnector function according to EN 60947-2
- Energy limiting class 3
- Easy replacement or expansion of your system through modular design
- Simple mounting by snapping onto the top-hat rail in Ex e enclosures
- Fixed thermal and magnetic trip units
- Ergonomically shaped operating lever ensures safe switching on and off
- Protection against re-switching during maintenance using padlocks (accessory)
