The T9AP1D52-24 is a single pole 30 amp relay with a 24VDC coil for compatible HVAC electric heat, relay, and fan control applications. Warren lists this relay as the alternate replacement for HD1-028D-A30PM2E, making it a common service part for electric heat control circuits.
This relay is commonly used with Warren CRR9 series time delay rectifiers, including CRR9-5, CRR9-9, and CRR9-18. It provides a normally open contact configuration and is used in compatible electric heat kits, air handlers, and HVAC control circuits where a 24VDC coil relay is required.
