Siemens SITOP PSE200U 6EP1961-2BA11 Load Protection

Product Overview

The Siemens 6EP1961-2BA11 is a SITOP PSE200U electronic selectivity module for 24 V DC systems.
It distributes power safely while protecting individual load circuits from overloads or short circuits.
Moreover, selective disconnection ensures unaffected loads continue operating during electrical faults.
Therefore, system availability improves significantly in demanding industrial environments.

This module supports multi-channel load separation without using conventional fuses.
In addition, electronic protection enables faster response times and higher operational reliability.
