SENTRON 3WA ACB Auxiliary Contact for Status Indication, Signaling and Control Circuit Applications – 3WA91110AD05

Product Description

🔹 Siemens SENTRON 3WA ACB Auxiliary Contact – 3WA91110AD05 (Status Indication & Control Application)

🔹 Product Description

The Siemens 3WA91110AD05 is a closing coil / shunt release (also referred to as auxiliary control accessory) designed for use with the SENTRON 3WA air circuit breaker (ACB) system. It is used for remote switching, control circuit operation, and status signaling functions in low-voltage power distribution systems.

This accessory plays an important role in automatic and remote operation of the ACB, enabling operators to close or trip the breaker electrically without manual intervention. It is commonly used in industrial power distribution panels, MCCs (Motor Control Centers), data centers, and critical infrastructure systems where remote control and system automation are required.

The device operates with a control supply voltage of 110–127V AC or 110–125V DC, making it suitable for continuous-duty applications. It ensures reliable switching performance and supports integration into PLC-based control systems and SCADA monitoring setups.

In SENTRON 3WA systems, this type of accessory enhances system availability, operational safety, and remote energy management capability, making it essential for modern intelligent power distribution networks.
