Product details

Panel fit and mounting constraints

The 3RA2115-1FA15-1AK6: Snaps onto DIN rail or screws in place with the additional push-in lug — the 45 mm width and 97.1 mm depth fit standard S00 feeder slots without crowding adjacent devices. Mounting position is vertical only; the 20 mm clearance above and 10 mm below are the minimum free air gaps for the bimetallic overload to track ambient temperature correctly.

Motor protection and trip coordination

Thermal bimetallic design, no electronic adjustment drift over temperature; the overload release is self-powered and does not draw from the control circuit.

Supplied components and wiring

Ships with the 3RT2015-1AK61 contactor and the 3RA1921-1DA00 link module pre-assembled — no separate ordering of contactor and overload, and the link module handles the power bus between them.

Environmental and compliance range

Operates from -20 to +60 °C ambient; storage range is -50 to +80 °C, transport range -55 to +80 °C — the wider transport window matters for unheated freight in winter. Pollution degree 3 rating means it is suited for industrial enclosures where conductive dust or occasional condensation is present, not just clean control rooms.

Frequently asked questions

What is the 3RA2115-1FA15-1AK6's width and depth for panel layout?

Width is 45 mm, depth is 97.1 mm — it occupies a single S00 feeder slot on the DIN rail with 20 mm clearance required above and 10 mm below.
