K8AK-AS1-phase control Single-phase current relay These single-phase current relays monitor over- and undercurrents.Manual resetting and automatic resetting are supportedby one relay. The start-uplock and operating time can be set separately. The relay warning status is easily monitoredwith the LED indicator. • Single-phase current relay • In 22.5 mm wide industrial housing • Under or over control • Supply voltages: 24 VAC/DC, 100 to 240 VAC • Easy wiring with ferrules Ordering information Measuring currentSupply voltage Order code 2 to 20 mA AC/DC, 10 to 100 mA AC/DC, 50 to 500 mA AC/DC 0.1 to 1 A AC/DC, 0.5 to 5 A AC/DC, 0.8 to 8 A AC/DC 10 to 100 A AC, 20 to 200 A AC 24 VAC/DCK8AK-AS1 24 VAC/DC 100 to 240VACK8AK-AS1 100-240VAC 24 VAC/DCK8AK-AS2 24 VAC/DC 100 to 240VACK8AK-AS2 100-240VAC 24 VAC/DCK8AK-AS3 24 VAC/DC 100 to 240VACK8AK-AS3 100-240VAC Accessories Current transformerInput range Applicable relayOrder code 10 to 100A AC, 20 to 200 A AC K8AK-AS3 K8AC-CT200L Note:The K8AK-AS3 is designed to be used in combination with the K8AC-CT200L (direct input not possible) Specifications Ambient operating temperature –20 to 60°C (with no condensation or icing) Storage temperature –25 to 65°C (with no condensation or icing) Operating voltage range85% to 110% of rated operating voltage Rated power supply frequency 50/60 Hz±5 Hz (AC power supply) Output relays (1 × SPDT, normally closed operation) Resistive load 5 A at 250VAC or at 30 VDC Maximum contact voltage250VAC or 30 VDC Maximum contact current5 A Maximum switching capacity1,250 VA, 150 W Mechanical life 10,000,000 operations Electrical life 50,000 operations at 5 A, 250VAC or 30 VDC Degree of protection Terminal section: IP20 Case materialPC and ABS WeightApprox. 150 g Operating power Isolated power supply2.0 VA/1.1 W max. at 24 VAC/DC, 4.6VA max. at 100 to 240 VAC Operate (SV)Operating value setting range 10% to 100% of maximum measuring current Operating value 100% operation at set value Reset (HYS.)Hysteresis5% to 50% of operating value Resetting method Manual reset/automatic reset (switchable) Manual reset: Turn OFF operating power for 1 s or longer Operating time (T)0.1 to 30 s Operating power ON lock (LOCK) 0 to 30 s (The startup lock timer starts when the input has reached approximately 30% or more of the set value.)
