Siemens LCE01C303277A Contactor
Coil and Contact Electrical Profile (LCE01C303277A)
The LCE01C303277A is a lighting contactor in Siemens' LCE01C series. Coil power draw is rated at 248VA with a nominal voltage of 277VAC; must-operate threshold is 235.5 VAC, giving approximately 15% pull-in margin. Contact rating is 30A across the full contact set. The contact form is 6PST combining 3NO and 3NC poles in a single package.

Construction and Environmental (LCE01C303277A)
Contact Arrangement
The six-pole configuration (3 Form A + 3 Form B) suits multi-phase lighting loads requiring independent NO and NC monitoring paths. All contacts are encapsulated in a box package. Auxiliary contacts are integrated as a standard feature.
Environmental
Operating temperature range is 25°C to 40°C. This is a relatively narrow band that restricts use to conditioned interior spaces; the contactor is not rated for unheated or outdoor panel environments without supplementary thermal management.
Coils Across the LCE01C303xxx Family
All alternates share the same contact rating, coil power, form factor, and auxiliary-contact feature. Differences are limited to coil voltage. Readers should qualify suitability independently.
| MPN | Coil Voltage | Must Operate |
|---|---|---|
| LCE01C303277A (seed) | 277VAC | 235.5 VAC |
| LCE01C303208A | 200–208VAC | — |
| LCE01C303240A | 230–240VAC | — |
| LCE01C303347A | 347VAC | 295 VAC |
| LCE01C303024A | 24VAC | 20.4 VAC |
| LCE01C303120A | 115–120VAC | — |
| LCE01C303480A | 460–480VAC | — |
| LCE01C303600A | 575–600VAC | — |
The LCE01C308277A shares the seed's 277VAC coil but uses 11PST (8NO/3NC) contacts instead of the 3NO/3NC arrangement. This increases available NO poles for downstream loads while retaining the same mechanical platform and thermal rating.
