Industrial RLYA25480 Solid State Relay 480VAC 25A

The RLYA25480 is a Philips ECG solid-state relay (SSR) designed for silent, maintenance-free switching of AC loads in industrial controls. It uses an optically isolated input to drive an AC-output switch rated up to 480 VAC and 25 A, configured as SPST normally open. This ECG Semiconductors part belongs to the RLYA family and is intended for panel- or equipment-level control where fast, reliable interruption of mains power is required without the wear and arcing associated with mechanical relays. The 480 VAC, 25 A rating captures the model’s mid-range power handling, making it suitable for applications such as heaters, fans, motors, and other line-powered loads in automation circuits. By separating the control circuitry from the high-voltage load, the SSR helps reduce interference and enhances safety in integrated control systems, while providing long service life due to the absence of moving contacts.
