R. STAHL LS Leitungsschutzschalter
Model: 8530/1-MCB-STA102-C1-500-3
Article No.: 267203
Product Overview
The R. STAHL 8530 series of miniature circuit breakers offers excellent current limitation for short circuits and high breaking capacity (10, 15, or 25 kA). This results in reduced stress on conductors and higher selectivity with upstream fuses. The modules are designed for modularity, available in 1- to 4-pole versions, and for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 module widths (TE).
Key Features:
- Trennerfunktion (Isolating function) according to EN 60947-2
- Energy limitation class 3
- Easy replacement or expansion of installations due to modular design
- Simple mounting by snapping onto mounting rails in Ex e enclosures
- Fixed thermal and magnetic trip units
- Ergonomically shaped operating lever ensures safe switching
- Protection against re-closing during maintenance via padlock (accessory)

Technical Drawings and Diagrams
Trip Time Curve (Auslösezeit)
The diagram shows the tripping characteristics for a Type C breaker. It illustrates the relationship between the multiple of the rated current (Vielfaches des Bemessungsstromes I/In) and the tripping time (Auslösezeit) in seconds and minutes. The curve indicates the threshold for tripping from a cold state (Grenzkennlinie aus dem kalten Zustand).
