R. STAHL LS Miniature Circuit Breaker 8530/1-MCB-STA103-C32-000-3
Article No. 272181
Key Features
- Trennerfunktion according to EN 60947-2
- Energy Limiting Class 3
- Easy replacement or expansion of your system due to modular design
- Simple mounting by snapping onto top-hat rails 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)
Product Overview
The 8530 series miniature circuit breakers from R. STAHL offer good current limitation for short circuits and high switching capacity of 10, 15, or 25 kA. This means less stress on the lines and higher selectivity to upstream fuses. The modules are designed modularly and are available in 1- to 4-pole versions for rated currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).
