3RU2936-3AA01

The 3RU2936-3AA01 is a stand-alone assembly support from Siemens' SIRIUS accessory line, designed to mount a compatible 3RU21, 3RB30, or 3RB31 overload relay independently rather than directly onto a contactor. Sized for Size S2 overload relays, it gives installers the flexibility to position the overload relay separately within a panel when direct contactor mounting isn't practical or desired. This purely mechanical accessory does not provide any electrical protection function on its own. The 3RU2936-3AA01 is compatible with Siemens' 3RU21, 3RB30, 3RB31, and 3RR2 overload relay families in the Size S2 frame class, letting you standardize on the same overload relay type whether it's mounted directly to a contactor or installed as a stand-alone device. This flexibility is useful when panel layout, wiring practices, or maintenance access make stand-alone installation preferable to direct contactor mounting. Mechanically, the 3RU2936-3AA01 uses screw-type main circuit terminals and mounts to standard DIN rail, providing a secure base for the overload relay it supports. Built to withstand ambient temperatures from -20°C to 70°C during operation, it's suited for a wide range of industrial and commercial panel environments. This makes the 3RU2936-3AA01 a practical, low-cost accessory for building or reconfiguring motor starter combinations.
