Siemens LEN00H003600A Contactor
This Siemens LE-series contactor is designed for chassis-mount industrial power-control applications, typically installed in motor-control centers or heavy-load distribution panels. The 830VA holding power rating is specified at the nominal coil voltage.
Contact Ratings and Configuration
| Spec | Value |
|---|---|
| Contact Form | 3PST-NO (3 Form A) |
| Contact Rating | 400 A |
| Coil Voltage | 575–600 VAC/DC |
| Coil Power | 830VA |
| Mounting | Chassis Mount |
| Operating Temperature | 0°C–40°C |
| Encapsulation | Box |
| Features | Auxiliary Contacts |
The 400A continuous rating places this in the high-current contactor class, suitable for main power switching rather than auxiliary control duties.
Coils for Siemens LE 400A Family
The seed is one voltage variant in a Siemens LE contactor series sharing 400A contacts, 830VA coils, and chassis-mount form factor. All variants use identical contact arrangements and auxiliary-contact complements.
| MPN | Coil Voltage | Similarity |
|---|---|---|
| LEN00H003600A | 575–600VAC/DC | — |
| LEN00H003480A | 440–480VAC/DC | 1.0 |
| LEN00H003240A | 220–240VAC/DC | 1.0 |
| LEN00H003277A | 240–277VAC/DC | 1.0 |
| LEN00H003208A | 200–220VAC/DC | 1.0 |
| LEN00H003120A | 110–127VAC/DC | 1.0 |
| LEN00H003024A | 23–26VAC/DC | 1.0 |
Voltage selection for new designs should match available control circuitry; coil power remains 830VA across the family.
Third-Party Alternatives
Siemens 3RT series contactors offer different form factors (chassis plus DIN rail mounting) and current ratings within the same voltage range.
| Spec | LEN00H003600A | 3RT12666AT36 | 3RT1065-6AP36 |
|---|---|---|---|
| Contact Rating | 400 A | 300 A | 265 A |
| Coil Voltage | 575–600 VAC/DC | 575–600 VAC/DC | 220–240 VAC/DC |
| Coil Power | 830VA | 700W | 650W |
| Mounting | Chassis | Chassis, DIN Rail | Chassis, DIN Rail |
| Operating Temp | 0–40°C | 25–60°C | 25–60°C |
Reader must qualify peers independently for specific application fit.
- 3RT12666AT36 shares the 575–600VAC coil voltage and auxiliary contacts; lower 300A rating and DIN-rail mounting option broaden panel mounting flexibility.
- 3RT1065-6AP36 offers DIN-rail mounting and a lower coil power draw, but steps down to 265A contacts at 220–240VAC, narrowing voltage compatibility.
