Model Description
Note ①: Depending on the current and starting mode, the ZSEEC1D series can be equipped with various specifications of external operating handles. Refer to the table of handle models and appearances at the end of the sample. Please confirm the specific handle specifications and model with the commercial department before ordering.
- Rated Current Values: 16, 25, 32, 40, 50, 63, 80, 95, 110, 150, 180
- Starting Mode: Star-delta start marked as Z, single direct start not marked
- Control Power Voltage:
- 16~95: 127, 220 (not marked), 380
- 110~180: 110, 220 (not marked), 380
- Manual Mechanism Auxiliary Contact Description: 16~180 default configuration is 2 normally open, 2 normally closed
- Contactor Auxiliary Contact Description: 16-95 products have one normally open and one normally closed switch; other currents do not include auxiliary contacts. For configuration with side-mounted auxiliary contacts, refer to the table below.
| Start Mode | Current Range | Auxiliary Contact Model | Contact Type | Description |
|---|---|---|---|---|
| Single Direct Start | 16-180 | F11 | 1NO 1NC | Optional F8-11 auxiliary module, can be factory pre-installed or self-assembled |
| Single Direct Start | 16-180 | F22 | 2NO 2NC | Optional F8-11 auxiliary module, can be factory pre-installed or self-assembled |
| Star-delta Start | 16-180 | F22 | 2NO 2NC | Optional F8-11 auxiliary module, can be factory pre-installed or self-assembled |
| Star-delta Start | 16-180 | F44 | 4NO 4NC | Cannot be self-assembled, must be factory pre-installed |
Note: If a single direct start contactor is selected, F11 is pre-installed by default on the right side; if a star-delta start contactor is selected, the auxiliary contacts should be equipped with one set for each of the two switches, with F22 pre-installed by default in the middle of the mechanism.
Example of Selection:
-
32A single direct start external operation, 220V control voltage, selected with one normally open and one normally closed side-mounted auxiliary contact model: ZSEEC1D-32/3JF11
-
