Zelio SSP3 Solid State Power RelaysSchneider Electric Zelio solid state relays provide a compact and innovative solution for a wide variety of applications with interfacing control and load switching. The SSP Series panel mount relays that offer complete solid-state control and switching solutions. SSP relays offer zero voltage switching for resistive loads and random switching for inductive loads. With single phase and 3 phase options and current ratings ranging from 6 A to 55 A.Easy maintenanceHigh switching frequencyResistance to shock, vibration and contaminationLong life spanSchneider Electric SSP3A250P7TThis Harmony SSP solid state panel mount 3-phase relay is rated 50A, is controlled with a 180V to 280V AC input, has a rated load voltage of 48V to 530V AC with zero voltage switching, ideal for resistive loads. It has a visual indicator showing the status of its input and a alarm output enabling a quick response to unexpected events. It also has a test button for easy debugging, testing and commissioning. It is also silent and reliable thanks to the absence of moving contacts.Schneider Solid State Relays
