Product details

S00 frame, 24 V coil — the panel-fit constraints

The 3RT2015-1BB42: The screw terminals are the standard choice for panel wiring where ring or fork terminals are preferred over spring cages.

Switching duty and thermal envelope

The AC-4 ceiling is the limiting factor for high-duty-cycle reversing or jogging applications. The 85 °C span between storage extremes covers most warehouse and transport conditions without special handling. These numbers define the DC switching capability for control circuits — the current drops sharply above 60 V, so confirm the load current at the actual control voltage.
