3WL9211-1AB10-0AA1 SIEMENS

The 3WL9211-1AB10-0AA1 is a guide frame accessory designed for use with Siemens 3WL series circuit breakers, specifically size I breakers ranging from 630A to 1000A. It is engineered to support breakers with a short-circuit breaking capacity of up to 66kA in a 3-pole configuration. This guide frame facilitates front connection of the breaker, with a dual-hole design for both top and bottom connections, ensuring secure and reliable electrical connections. The accessory is equipped with one auxiliary plug connector, enabling the integration of additional control or monitoring circuits. However, it does not include auxiliary current plug connectors, simplifying the wiring configuration for certain applications. Furthermore, this model is designed without a position signaling switch, which may be suitable for applications where remote position indication is not required. The guide frame also omits a shutter mechanism, focusing on core functionality and ease of installation. This accessory enhances the breaker's stability and connection integrity within electrical panels and switchboards. It is crucial for maintaining safe and efficient power distribution.
