Description

SIA-C Relays are Dual & Self powered overcurrent and earth fault Protection Relays, that obtein the energy to power itself tanks to STANDARD CURRENT TRANSFORMES on the lines. Besides, due to the low consumption of this relay, the required burden of the CTs is very low (2.5 VAs for 1 A nominal current or 5 VAs for 1 A nominal current. SIA-C is provided with a really low pick-up level (0.1xIn) and its complete electronic allows to record up to 1024 events and 20 fault reports which are saved with the date and time at the moment of the recording thanks to the internal real time clock (RTC). On the other hand, the SIA-C can be also Dual-powered Relay (working with auxiliary voltage) and offers up to 3 configurable LEDs and up to 3 magnetic indicators to signal the trip. Regarding the communication and depending on model, rear communication (RS485 – Modbus RTU) can be selected. Considering these advantages, SIA-C can be used in multiple applications, and different mechanics have been developed to cover all clients’ requirement. 50_1, 50/51, 50N/G_1, 50/51N/G, 74TCS, PGC, 50_2, 50N/G_2, CLP, 49, 46, 46BC, 50BF, 74CT, 79, 52, SHB, 49 and 68 protection functions. Main Applications: Transformation substations. RMUs and SF6 insulated Switchgears.
