17717479099 | ECS125P ELECTRONIC CENTRIUGAL SWITCHES FOR CAPACITOR START(& RUN)INDUCTION MOTORS Model name：ECS125P operating voltage ：AC 100-120V, 50/60Hz Application：CSIR or CSCR motors (0.18~2.2kW) |
Description
These models are designed for both capacitor start motors and two
(start + run) capacitors motors, For motor operating voltage of 220VAC
Please refer to typical wiring diagram of this datasheet.
Feature
Extended life span of switching contacts
High compatibility with various motor designs
Improved motor starting efficiency
Neither switching noise nor trembling of contacts
Protect auxiliary windings or start capacitors
Return immediately from unwanted reverse motor rotation
Mounted on either inside / outside motor frames
Discharge start capacitors with built-in resistors
Electrical characteristics (typical)
| Parameter | Value | Unit |
| Line voltage, VL | 100~120 | VAC |
| Non repetitive peak current @ half cycle, 50/60Hz | 250 | A |
| Thermal impedance @ 7.4sec, 25A | 2.4 | ℃/W |
| Switch-on delay time @ 50/60Hz | 2.0 | Cycle |
| * Discharge resistance | 12 | KΩ |
**Forced switch-off locked rotor time，60Hz（50Hz） | 7.4(8.8) | s |
| **Maximum Number of successive restarts | 9 | - |
| Forced switch-off starting coil voltage | 200~250 | VAC |
