Market Definition
A solid-state relay (SSR) is a semiconductor device that is used to switch electricity to a load when a small external voltage is applied across control terminals. The SSR can be designed to switch either AC or DC to the load. SSRs have no movable contacts. They, however, employ semiconductor switching elements, such as thyristors, TRIACS, diodes, and transistors. The different types through which SSRs can be mounted in a circuit include panel mount, PCB mount, DIN-Rail mount, and others.
The solid state relay ecosystem with a power system includes various electronic components such as a generator, transformers, transmission lines, isolators, circuit breakers, bus bars, cables, relays, instrument transformers, distribution feeders, and various loads. The market is diversified, with more than 30 companies competing across the value chain to sustain their position in the market and increase market share.
