Product details

Panel fit and mounting constraints

The 3RA2150-4EA35-0AP0: The fastening method accepts screw fixing or snap-on mounting to two parallel 35 mm DIN rails, and the unit can be mounted vertically or horizontally. Clearance requirements around the starter: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, and zero backwards. These gaps must be free for cooling airflow and arc-fault containment.

Motor protection and switching duty

The supplied contactor is a 3RT2035-1AP00, a standard SIRIUS frame for this current class.

Environmental limits and compliance

Operating temperature range is -20 to +60 °C with temperature compensation active across the same band. Storage and transport limits are -50 to +80 °C.
