Catalog 1308242 Issued 3-03 P&B KUL series 10 Amp Magnetic Latching Relay File E22575 File 15734 Users should thoroughly review the technical data before selecting a product part number. It is recommended that users also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. Coil Data Features * Single or dual-wound DC coils or single-wound AC coils. * Contact arrangements to 3PDT. * Reset occurs by reversing polarity in a single coil relay or by energizing the reset winding in dual coil relays. * Uses same sockets as other KU relays. * Well suited for applications such as alarm systems, machine tools, battery chargers and process controls.

On standard dual coil relays, the latch and unlatch voltage must be the same. For unlike voltages, please contact your sales representative. ** Diodes and resistors included inside relay with 1 and 2 Form C contacts. For 3 Form C relays, the customer must furnish and wire diodes and resistors externally. 15% for AC coils. Operate Data @ 25C Must Operate Voltage: DC Coils: 75% of nominal voltage. AC Coils: 85% of nominal voltage. Operate Time : 25 milliseconds maximum at nominal voltage. Release or Reset Time: 25 milliseconds maximum at nominal voltage. Initial Dielectric Strength Between Open Contacts: 500V rms. Between Adjacent Contacts: 1,500V rms. Between Contacts and Coil: 1,500V rms. Environmenal Data Coil Data @ 25C Duty Cycle: Continuous. (Latch and reset not to be energized simultaneously). Initial Insulation Resistance: 100 megohms, minimum. Initial Breakdown Voltage: 1500V rms, 60 Hz. between all elements. Temperature Range: Storage: -45C to +105C. Operating: Single Coil AC & DC: -45C to +70C. Dual Coil DC: -45C to +50C. Mechanical Data Note: On single coil AC models one terminal is common. Latch/Reset function is accomplished by input in series with a diode to provide the correct polarity to the coil. To perform either function, the terminal not being used (Latch or Reset) must be open or isolated with no other path to common or ground. Dimensions are shown for 908 reference purposes only. Dimensions are in inches over (millimeters) unless otherwise specified. Termination:.187" (4.75mm) quick connect/solder terminals. Sockets are available. Enclosure: Clear plastic polycarbonate heat and shock resistant case. Weight: 3.4 oz. (96g) approximately.
