FAQ of AM2SE Protection Relay

How to set the CT and PT ratio of the protection device?

The protection device can set the CT and PT ratio through the fixed value menu. For example, the current transformer is 75/5 and the voltage transformer is 10/0.1, then the CT ratio is set to 15 and the PT ratio is set to 100.

For AM4, if you want to place a circuit line protection and transformer protection, how to distinguish the model?

AM4 is suitable for circuit protection and transformer protection. No need to distinguish between models when placing orders

When the voltage is three-phase three-wire system, does the current have to be connected with 2CT?

The voltage wiring mode and current wiring mode of the protection device can be set independently, and can be connected freely.

How to confirm whether the anti-trip function is configured?

If the circuit breaker is equipped with anti-trip, the device does not must be equipped with anti-trip; if the circuit breaker does not have anti-trip, you need to configure the AM5-FT anti-trip module. (If DC48V is selected as the operating power supply, the anti-trip box is not optional, and the circuit breaker must be equipped with anti-trip function; if you choose AC anti-trip, please note that AC and DC general anti-tripping)

How to purchase suitable protection devices?

Before ordering, it is recommended to consult related engineers, select the appropriate protection model,

and then fill in the corresponding selection table, and place the order after confirmation by the engineers.
