Zelio relay Semiconductor relay for mounting on a heatsink or on mounting plate. The low internal voltage drop reduces the heat loss. The load circuit is designed for 3-phase networks in the range of 48-530 VAC and each phase can be switched 25 A. The switching behavior is momentary switching and corresponds to 3 closer contacts. The control voltage takes place with 4-32 VDC and switches all 3 phases. An LED display informs about the control. Ideal for controlling resistive and inductive loads as per data sheet. The internal switching output is also equipped with an RC-wiring and surge protection. To select the separate heat sink, you have to consider heat.This text is machine translated.
