Over-Voltage Protection 2 (OVP2)

• Over-Voltage Protection: Provides over-voltage protection for applications such as isolation joints, including protection against lightning and AC fault current.
• AC and DC Isolation: Provides AC and DC isolation for voltages below the selected voltage blocking level and an effective grounding (or coupling) path whenever voltage attempts to exceed the blocking level.
• Automatic Reset: Instantly switches to the shorted mode when voltage exceeds the selected threshold, providing over-voltage protection. After the event is over, the device automatically switches back to the blocking mode.
• Solid-State Design: Uses proven solid-state components with an instantaneous response to voltage, initiating voltage clamping immediately when voltage attempts to exceed the selected blocking level.
• Fail-Safe and Maintenance-Free: If failure occurs due to AC fault current or lightning impulse current, the device fails in the shorted mode, maintaining an effective grounding path. The OVP2 is completely maintenance-free.

• Blocking Voltage Ratings: Standard: -2 V/+2 V; optional: -3 V/+1 V and other lower blocking voltage combinations.
• AC Fault Current Ratings (Amps AC-RMS Symmetrical, 50/60 Hz): 1 cycle: 2,100 A at 1.2 kA, 5,300 A at 2 kA, 6,500 A at 3.7 kA and 8,800 A at 5 kA; 3 cycles: 1,600 A, 4,500 A, 5,000 A and 6,800 A, respectively; 10 cycles: 1,400 A, 3,700 A, 4,200 A and 5,700 A, respectively; 30 cycles: 1,200 A, 2,000 A, 3,700 A and 5,000 A, respectively.
• Maximum Voltage During AC Fault Current: Less than 10 V AC under the maximum fault current ratings.
• Impulse Current Withstand Rating: Standard: 100 kA crest, 8 × 20 microseconds for all models; optional Class N: 50 kA crest, 10 × 350 microseconds for the 5 kA model.
• DC Leakage Current: Normally less than 10 mA at maximum blocking voltage at 20°C and less than 100 mA at 65°C. Under normal cathodic protection voltage, typically well under 1 mA.
• Enclosure: Molded, non-metallic enclosure; IP68 rated to 2 m depth; suitable for indoor or outdoor use in submersible and non-submersible applications.
• Temperature Range: -45°C to +65°C (-49°F to +149°F).
• Electrical Connection: Polarity-marked positive and negative terminals. The negative terminal connects to the more negative structure or structure with cathodic protection; the positive terminal connects to the grounded or more positive structure.
• Mounting: Multiple mounting options available. Optional stainless steel mounting bracket (MTG-OVP2) must be ordered separately.
• Energy Requirements: None. The device is totally passive.
• Number of Operations: Virtually unlimited under rated lightning or AC fault current conditions, provided operations are not immediately repetitive.
• Certifications: Class I, Division 2, Groups A, B, C and D; Zone 2, Group IIC. UL and C-UL certifications for the Class and Division system; ATEX, IECEx and UKEx for the Zone system.
