LS Miniature Circuit Breaker

Model: 8530/1-MCB-STA102-B20-000-2

Article No.: 293919

Product Description

The R. STAHL 8530 series miniature circuit breakers offer excellent current limitation for short circuits and high breaking capacity of 10, 15, or 25 kA. This results in reduced stress on conductors and higher selectivity to upstream fuses. The components are modularly designed and available in 1- to 4-pole versions for rated currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).

Key Features:

Trennerfunktion (Isolating function) 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 a mounting rail in Ex e enclosures
Fixed set thermal and magnetic releases
Ergonomically shaped operating lever ensures safe switching on and off
Protection against re-switching during maintenance using padlocks (accessory)
