Description

This Harmony SSP solid state panel mount 3-phase relay is rated 50A, is controlled with a 18V to 36V 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. 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0

Features

Engineered for high-demand automation, this solid state relay supports a robust 50A per channel across a rated voltage range of 42V to 660V AC, ensuring reliable performance without contact wear. It is the ideal solution for switching heavy resistive or inductive loads in conveyor systems, packaging machinery, and industrial ovens prone to voltage fluctuations.
This 3-phase solid state relay consolidates multi-line switching into a single compact housing, saving significant DIN rail space compared to three individual single-phase units. It ensures simultaneous switching across all three phases, mitigating phase-unbalance risks in heavy industrial motors and heating elements.
Fully compliant with UL, CSA, and CE standards, this Schneider Electric Harmony Solid State series relay features a completely solid-state design with no moving parts, promising millions of trouble-free operating cycles. Its rugged build eliminates the arcing, pitting, and mechanical fatigue common to traditional magnetic contactors.
