## **Solid State Relays Industrial, 1-Phase ZS w. LED Types RS 23, RS 40, RS 48** - **Zero switching AC Solid State Relay** - **Direct copper bonding (DCB) technology in 25A and 40A types** - **LED indication** - **Clip-on IP 20 protection cover** - **Self-lifting terminals** - **Housing free of moulding mass** - **2 input ranges: 4-32 VDC and 18-36 VAC/VDC** - **Operational ratings up to 40 AACrms and 480 VAC** - **Blocking voltage: Up to 1200 Vp** - **Opto-isolation: > 4000 VACrms** - **Integrated snubber network in 25 A and 40 A types** ## **Product De scri tion p** ~~———_—_—_————S a~~ LED indicates the status of the control input. The clip-on cover is securing touch protection to IP 20. Output terminals can handle cables up to 16 mm[2] . The zero switching relay with triac (10 A) or thyristor output (25 A, 40 A) offer a solution for resistive load switching. The zero switching relay switches ON when the sinusoidal voltage crosses zero and switches OFF when the current crosses zero.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 540,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
