LS Miniature Circuit Breaker 8530/1-MCB-STA102-B16-000-2

Article No. 293918

Components for System Technology

The R. STAHL LS Miniature Circuit Breakers of the 8530 series offer good short-circuit current limitation and high switching capacity of 10, 15, or 25 kA. This results in low stress on the lines and high selectivity to upstream fuses. The units are modularly designed and available in 1- to 4-pole versions for nominal currents from 0.5–63 A. The maximum installation capacity is 4.5 modules (TE).

Trennerfunktion according to EN 60947-2
Energy limitation class 3
Easy replacement or expansion of your system through modular circuit breaker 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 on and off
Protection against re-switching during maintenance using padlocks (accessory)
