Page 2: Safety Information
SPD50K Safety Information Important Information Read these instructions carefully and look at the equipment to become familiar with the device before trying to install, operate, service or maintain it. The following special messages may appear throughout this bulletin or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure. - Page 3 SPD50K Precautions DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH • Apply appropriate personal protective equipment (PPE) and follow safe electrical work practices. See NFPA 70E, NOM-029-STPS or CSA Z462. • This equipment must only be installed and serviced by qualified electrical personnel. •...

SPD50K Storage The device should be stored in a clean, dry environment. Storage temperature is -67 °F to +149 °F (-55°C to +65°C). All of the packaging materials should be left intact until the device is ready for installation. Identification Nameplate The identification nameplate is located on the side of the unit. -
Page 6: Equipment Performance
SPD50K Equipment Performance To obtain optimum surge suppression, locate the SPD as close as possible to the circuitry being surge-limited to minimize the wire length. Minimizing the wire length reduces the impedance between the circuitry and the SPD. Refer to the Voltage Protection Rating (VPR) values on the SPD nameplate. These VPR values were obtained by testing the SPD with six-inch long leads (per UL1449). -
Page 7: Voltage Rating
SPD50K Dimensions (in./mm) (L-BRACKET IS INCLUDED) Electrical DANGER HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH • Confirm the surge protective device voltage rating on the module or nameplate label is not less than the operating voltage. Failure to follow these instructions will result in death or serious injury. Voltage Rating Prior to mounting the SPD, verify that the device has the same voltage rating as the power distribution system in which it is installed. - Page 8 SPD50K Table 1: Model SPD50K Service Voltages Surge Protective Device 50kA Rating Per Phase Voltage Codes 10S – 120V/240V 10Y – 208Y/120V 27Y – 480Y/277V 24D – 240V Delta 48D – 480V Delta 34Y – 600Y/347V 60D – 600V Delta System Reference Configuration...
- Page 9 SPD50K Location of Surge Protective Device (SPD) UL 1449 Type 1 SPDs have been designed and approved for line side applications prior to the main service dis- connect without supplemental overcurrent protection. Type 2 SPDs must be installed on the load side of the main Overcurrent Protective Device (OCPD).
