What this part is and what it does
The TeSys Deca LC3D80E7A64 is a pre-wired star delta starter from the TeSys range, designed for motor control under AC-3 utilisation category. It carries three power poles, each configured as 3 NO, and is rated for 80 A with a 48 V AC coil. The IP20 front face protection means the front of the unit is touch-safe inside an enclosure, but it is not rated for washdown or outdoor exposure — it belongs inside a panel. It operates from -40 to 140 °F (-40 to 60 °C) with derating possible up to 158 °F (70 °C), and can be stored from -76 to 176 °F (-60 to 80 °C). The pollution degree 3 rating means it is suitable for industrial environments with conductive or dry non-conductive pollution.
Lifecycle and sourcing reality
The part carries a flame retardance rating of V1 per UL 94 and fire resistance tested to 1562 °F (850 °C) per IEC 60695-2-1, with protective treatment per TH IEC 60068-2-30. These are useful for quality documentation when verifying compliance against legacy panel specifications.
Integration notes for the panel
The star delta starter is pre-wired, which simplifies installation into a motor control centre. The 3 x 3P pole configuration means it handles the six main power connections typical of a star-delta transition. The 48 V AC coil is a control voltage that must match the existing control transformer or PLC output — verify before wiring. Mechanical robustness is specified for vibrations at 2 Gn (contactor open) and 3 Gn (contactor closed) over 5...300 Hz, and shocks at 8 Gn for 11 ms (open) and 10 Gn for 11 ms (closed). This is adequate for most industrial panel environments but should be reviewed if the panel is mounted on a high-vibration machine.
