It uses “zero crossover” switching (i.e. it switches when the AC waveform crosses zero to reduce switching noise)

It’s rated for 90 A output current

Input side: 4–32 V DC or 4–16 mA (i.e. can be driven by a DC voltage or current signal)

Output side: 24–600 V AC at 47–63 Hz

Peak Inverse Voltage (PIV) ~ 1600 Vpk

Body-to-body isolation (insulation) ~ 6 kV for 1 minute; input-to-output isolation ~ 8 kV for 1 minute

It has a copper plate of 2 mm thickness (without heat sink) as part of its structure.

It is a solid state relay (SSR) / SCR / analog phase‑angle control SSR made by Unison.
Input: 4‑20 mA (or also 0–10 V option)
Output: 440 VAC, 90 A
The “44” in the code likely refers to “440 VAC” rating.
The “420” may be part of its internal coding for the design or series.
It uses copper (CU2) for conduction / heat paths.
It’s designed in a 45 mm “hockey puck” form factor.
It has some parameters like PIV, isolation etc (for analogous model): e.g. PIV ~1200 Vpk, isolation input-output ~6 kV for 1 min.
