R. STAHL Circuit Breaker 8530/1-MCB-STA103-C63-000-3

Article No. 267213

Product Description

The R. STAHL 8530 series circuit breakers offer excellent current limitation in case of short circuits and high breaking capacities of 10, 15, or 25 kA. This results in reduced stress on electrical lines and high selectivity with respect to upstream fuses. The modules are designed with a modular structure, available in 1 to 4 pole versions and for nominal currents from 0.5–63 A. The maximum mounting capacity is 4.5 division units.

Key Features:

Disconnecting function according to EN 60947-2
Energy limiting class 3
Simple replacement or expansion of installations due to modular design
Easy mounting via DIN rail clip 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)
