Type 1 Surge Protective Device, 480Y/277 VAC, Three Phase WYE
P3277-YB
P Series Type 1 Surge Panel, 480Y/277 VAC, Three Phase WYE, Max Surge Current Rating of 25kA per Mode/50kA per Phase, 200kA Short Circuit Current Rating (SCCR), 20kA I-nominal (ln) Rating, NEMA 4X Rated Enclosure, Thermally Protected MOVs, VPR Performance Data = L-N: 1200, L-G: 2500, N-G: 1000, L-L: 2000, Maximum Continuous Operating Voltage (MCOV): 350V/700V, Plastic Enclosure, LED Status Monitoring, Audible Alarm, UL 1449 Listed, Approximate Lead Length = 16"
- Leviton surge protective devices (SPDs) divert damaging voltage transients, or surges, away from electronic equipment
- Designed for RESIDENTIAL AND LIGHT COMMERCIAL APPLICATIONS, the P Series provides protection in single, split or three phase configurations
- Code Compliant – in 2020, Article 230.67 of the National Electrical Code® (NEC) updates required all services supplying dwelling units to be provided with a surge protective device (SPD), as an integral part of equipment or located immediately adjacent. The SPD must be a Type 1 or Type 2 SPD. The 2023 code expanded the requirements to dormitory units, guest rooms and guest suites of hotels and motels, and areas of nursing homes and limited-care facilities used exclusively as patient sleeping rooms

Max Surge Current Rating (Surge Capacity)
- The maximum amount of current the device is capable of diverting to ground during a single surge event without performance degradation of more than 10%
- Higher values are better
Nominal Discharge Current Rating (In)
- The amount of current the device can divert to ground 15 times under specific test conditions and maintain performance levels
- Higher values are better
Voltage Protection Rating (VPR)
- The maximum voltage a surge protector will let through to connected devices
- Lower values are better
Short Circuit Current Rating (SCCR)
- The maximum current a device or system can safely withstand for a specified time, or until a specified fuse or circuit breaker opens and clears the circuit
Maximum Continuous Operating Voltage (MCOV)
- Maximum line voltage (or V rms) that may be applied to the SPD without damaging the MOV
- A lower MCOV rating allows for a lower VPR, but decreases the life of an MOV
Modes of Protection
- A mode is a path that has an SPD component between two electrical points
- More modes is better
- 7-Mode example:
- L1-N, L2-N, L3-N, L1-G, L2-G, L3-G, N-G
