| Fully Automatic Transfer Switch | Thermal Magnetic Switch Transfer System |
|---|---|
| Manufactured according to IEC 60947-3 standards. Low-voltage switching and control devices, Part 3: Switches, disconnectors, disconnectors and fuse combination units. | Manufactured according to IEC 60947-2 standards. Low voltage switching and control devices, Part 2: Circuit breakers. |
| A single housing consists of two 0-I unfused load disconnectors. | It consists of two TMŞ (Total Values) combinations. |
| It does not have thermal magnetic protection features. | It has thermal magnetic protection features. |
| The transfer system does not require any extra accessories. | The transfer system requires a tripping coil, a closing coil, and a low-voltage coil. |
| It has a motor mechanism. | It requires a motor mechanism. |
| It has a mechanical lock. | It requires a mechanical lock. |
| Its position can be observed via a mechanical indicator or LED. | The positions can only be observed mechanically. |
| It has one CO contact each for positions I and II. | The auxiliary contact is available as an accessory. |
| It has positions I-0-II, and a padlock can be attached in all positions. | It has I-II positions, and a padlock is supplied as an accessory. |
| It features a 5x20 250V 10A porcelain fuse that protects the motor and PCB. | They do not have a system to protect their motor mechanisms. |
| With its dip switch, it can switch to 'contactor' mode in a single movement, meaning it remains in that position as long as it receives a signal, and returns to the 0 position if it does not receive a signal. | They do not operate in contactor mode. The system only works in positions I and II. |
| It has a simple control system. | It has a much more complex control system. |
| It has a sliding contact system. The contacts do not stick or overlap. | It has an open contact system. There is a possibility of contacts sticking and system interference. |
| It has breaking capacities of 50kA and 100kA. | They have variable breaking capacities. Generally, they do not have a 100kA breaking capacity. |
| It takes up less space compared to TMŞ (Transformers). | They take up more space compared to transfer switches. |
| Troubleshooting and resolving problems is much easier. | Troubleshooting and resolving the problem is much more difficult. |
| Three poles and four poles have the same length. | Three-pole and four-pole models have different lengths. |
| It's very easy to mount on the panel. | The panel mounting process is very detailed and unforgiving of errors. |
