Product details

Active production — what that means for your BOM line

The 3RA2115-1CD15-1AP6: The unit ships as a factory-assembled combination: a 3RT2015-1AP61 contactor, a thermal bimetallic overload relay, a link module (3RA1921-1DA00), and a busbar adapter (8US1251-5DS10) for snapping onto 60 mm busbar systems. Mounting position is vertical.

Motor ratings and trip coordination at line voltages

At 400 V AC-3, the unit is rated for 750 W motor load. At 480 V the full-load current is 2.15 A; at 600 V it is 2.24 A. AC-3 switching voltage is rated up to 690 V maximum, covering 400 V, 480 V, and 600 V line supplies common in North American and European panels.

Panel fit and clearance envelope

Dimensions: 45 mm wide, 200 mm high, 155.1 mm deep. Clearance requirements: 20 mm upward, 10 mm downward, 9 mm at the sides, zero forward or backward. This fits standard S00 feeder spacing on a DIN rail or busbar system. Ambient operating range is -20 to +60 °C; storage range is -50 to +80 °C. Pollution degree 3 means it tolerates conductive dust and humidity typical of industrial control panels without conformal coating.
