The PR Series power relays are ideal multi-voltage input pilot duty relays that mount to existing panels to control loads. External enclosures are not required making them ideal for interfacing loads with building automation control systems. Featuring the highest output in the smallest package, integrated current sensing, and a secure tamper resistant HOA. Highest 20A capacity in the industries smallest package.
- Command contactors
- Control motors
- Isolation
- Device interlocking
- Relay logic
- Lighting load levels
- Great for data centers using Hand Off Auto (HOA) switch
