Details on the Relay are:
Low Voltage Thermostat circuit .210A at 18V AC
240V. 60 Cy. 25A Non-Inductive
3.0 HP Switch SPST NO (Single Pole Single Throw - Normally Open)
I’m sorry, I found nothing to replace the HWC-23 Relay.

I believe that might be referred to as a “dry contact input relay”. Stated differently, a relay designed to allow control of an AC line-powered device from another such as the old Honeywell mercury-switch thermostats. In the form pictured, it’s tech that’s probably at least 20 years out of fashion.
Agreed with Rhonda on not finding a decent replacement to offer among our listings. Depending on the specific circumstances, consulting with a local electrician or HVAC technician may be advisable.
