The Harmony SSP3 series includes solid state relays with 3 phases and is designed for use in mechanical engineering, the packaging and textile industries, HVAC, low/medium voltage switchgear or in buildings. This solid state relay is zero voltage switching and therefore ideal for resistive and inductive loads. The load circuit is designed for 3-phase networks in the range of 42-660V AC and 50 A can be switched per phase. The control voltage is 18-36V AC and switches all 3 phases. The solid state relay switches silently, reliably and has a longer service life because it has no moving contacts. An LED display provides information about the control. The factory-fitted heat dissipation foil enables quick, easy and clean installation because no thermal paste or pads are required. The low internal voltage drop reduces the power loss heat. A heat analysis must be carried out to select the separate heat sink. Suitable for international use due to the large number of existing product standards and certifications.
