What stands out about this relay is its White-Rodgers branding, a name long associated with electrical components.
White-Rodgers Type 91 Power Relay 90-340/91-901 24VAC DPDT 12A 4-Pin
You will find that the White-Rodgers brand on this relay is a detail that brings peace of mind.
I like how the heavy duty housing protects the coil, even the panel sees bumps and knocks sometimes.
