Product details

Panel fit and mounting constraints

The 3RT2448-1AP60: Physical envelope: 152 mm deep, 70 mm wide, 140 mm high. These spacing figures govern the minimum panel cutout and adjacent device placement for arc flash and heat dissipation.

Auxiliary contact ratings and wiring

This contactor ships with an integrated auxiliary switch block (screw-type terminals for the magnet coil).

Environmental and switching characteristics

Power factor at rated load is 0.36 at 50 Hz and 0.4 at 60 Hz — relevant for sizing upstream protection and calculating real power draw.
