The SIEMENS 3RU2946-3AA01 is a mounting adapter specifically developed for the independent installation of thermal and electronic overload relays from the 3RU21, 3RB30, and 3RB31 series. This accessory allows these relays to be mounted separately from contactors, providing more flexibility in control cabinet design and improving thermal separation.

Key Features:

• Compatible with: 3RU21, 3RB30, 3RB31

• Enables standalone mounting without direct coupling to contactors

• DIN-rail mountable for simplified panel integration

• Ideal for decentralized or remote installation of relays

• Improves heat dissipation by physical separation of components

• Compact and durable industrial-grade construction

• Supports flexible and space-efficient panel layout
