R. STAHL LS Leitungsschutzschalter 8530/1-MCB-STA103N-B32-000-4

Art. Nr. 293849

Product Overview

The R. STAHL 8530/1-MCB-STA103N-B32-000-4 is a miniature circuit breaker designed for system technology applications. These circuit breakers offer good current limiting capabilities for short circuits and high breaking capacities of 10, 15, or 25 kA. This results in reduced stress on the connected 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:

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 top-hat rails in Ex e enclosures
Fixed thermal and magnetic trip units
Ergonomically shaped actuating lever for safe switching on and off
Protection against re-switching during maintenance using padlocks (accessory)
