APPLICATIONS ▪ Command contactors ▪ Control motors ▪ Isolation ▪ Device interlocking ▪ Relay logic ▪ Lighting load levels PRU1 Series Pilot Relays 10A 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 PRU1CSPDT10-30VAC/DC, 120VAC10ASmall PRU1CMSPDT10-30VAC/DC, 120VAC10AN.O. 1A @ 30VAC/DC, 0.3A TRIPSmall PRU1SSPST N.O.10-30VAC/DC, 120VAC10A Medium PRU1SMSPST N.O.10-30VAC/DC, 120VAC10A N.O. 1A @ 30VAC/DC, 0.3A TRIPMedium Hinged HOA cover with screw retention minimizes tamperingHigher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 23 Higher Reliability, Faster Installation, Superior Accuracy | Sense the difference | 23 CURRENT Pilot Duty Relays CONTACT RATINGS(PRU1C) 10 Amp Resistive @ 277 VAC 10 Amp Resistive @ 28 VDC 480 VA Pilot Duty @ 240-277 VAC 480 VA Ballast @ 277 VAC Not rated for electronic ballast 600 Watt Tungsten @ 120 VAC (N.O.) 240 Watt Tungsten @ 120 VAC (N.C.) 1/3 HP @ 120 VAC (N.O.) 1/6 HP @ 120 VAC (N.C.) 1/4 HP @ 277 VAC (N.O.) 1/8 HP @ 277 VAC (N.C.)
