APPLICATIONS ▪ Command contactors ▪ Control motors ▪ Isolation ▪ Device interlocking ▪ Relay logic ▪ Lighting load levels PR24 Series Power Relays 20A range resistive rating Hand Off Auto switch option Current run-status confirmation option DESCRIPTION The PR Series pilot 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. Convenient and cost-effective control ▪ Current sensor run status option ▪ LED indicator ▪ Multi-voltage coil input ▪ Hand-Off-Auto switch option Compact enclosure mounts externally for easy installation ▪ Nipple mount to any electrical enclosure ▪ Flexible tinned stranded wire… fits easily in tight spaces and provides secure connections to wire nuts Concealed HOA switch with screw secured cover prevents tampering ▪ Versions with Hand Off Auto (HOA) switch feature with secure screw cover door to prevent tampering ▪ Eliminates costly system override related service calls Run status confirmation ▪ True current sensing provides proof of load feedback that pilot device relay coil is powered FEATURES APPLICATIONS ▪ Command contactors ▪ Control motors ▪ Isolation ▪ Device interlocking ▪ Relay logic ▪ Lighting load levels MODELCONTACTCOIL INPUTCONTACTHOACURRENT RUN STATUSENCLOSURELED PR2401BSPDT24-30VDC, 24VAC, 120VAC20ASmall PR24BMSPDT24-30VDC, 24VAC20AN.O. 1A @ 30VAC/DC, 0.3A TRIPSmall PR2401SBSPST N.O.24-30VDC, 24VAC, 120VAC20A Medium PR2401SBMSPST N.O.24-30VDC, 24VAC, 120VAC20A N.O. 1A @ 30VAC/DC, 0.3A TRIPMedium Hinged HOA cover with screw retention minimizes tamperingHigher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 21 TYPICAL WIRING CURRENT Power Relays CONTACT RATINGS(PR2401B/PR24BM) 20 Amp Resistive @ 277 VAC/30VDC NO/NC 1HP @ 120VAC NO/NC 2HP @ 277VAC NO/NC 20A @ 120/277VAC STANDARD BALLAST NO 1100VA Pilot Duty @ 277VAC Not rated for electronic ballast 10A @ 120VAC TUNGSTEN NO PR2401BPR2401SB White/Yellow Common COMM Wht/Yel Blue N.C.
