XSSR-H Series Modular DIN Rail Mounted Single-Phase AC Solid State Relay
DIN-rail modular SSR for compact control-cabinet installation
XSSR-H Series Modular DIN Rail Mounted Single-Phase AC Solid State Relay is part of XURUI’s public solid-state relay and voltage-regulator portfolio. The page is structured around control signal, output/load type, current, mounting, thermal design and protection. Exact ratings must be confirmed against the current model datasheet and heat-sink calculation.
Final ratings, dimensions and approvals must be confirmed against the exact model code and current controlled documents.

XSSR-H Series FAQ
How should this SSR be sized?
Start with load voltage, load current, resistive or inductive behavior, switching frequency, ambient temperature and heat-sink conditions. Do not select only from nominal current.
What thermal information is required?
Provide ambient temperature, enclosure ventilation, duty cycle, mounting and allowed heat-sink size.
Can XURUI review a replacement model?
Yes. Send the existing SSR model, control signal, load, wiring diagram, panel space and required approvals.
