Model: 8530/1-MCB-STA103-C32-000-3

Part Number: 272181

Product Overview

The R. STAHL 8530/1-MCB-STA103-C32-000-3 circuit breaker is designed for systems technology, offering good current limitation in case of short circuits and a high breaking capacity of 10, 15, or 25 kA. This reduces the load on electrical lines and provides high selectivity with upstream fuses. The modules feature a modular structure, available in 1 to 4 pole versions, with nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.

Key Features:

Separator function according to EN 60947-2
Energy limitation class 3
Easy replacement or expansion of installations due to modular design
Simple mounting by clipping onto the DIN mounting rail in Ex e enclosures
Fixed thermal and magnetic trip adjustment
Ergonomic operating lever for safe connection and disconnection
Protection against reconnection during maintenance using padlocks (Accessories)
