OD3Mag™ Dimensional Info
With the OD3Mag™ breaker, JST combines field proven magnetic actuation with independent pole operation to achieve the first ever single-phase capable substation circuit breaker.
The OD3Mag™ Breaker is designed to help improve utility SAIDI and SAIFI scores. With magnetic actuation, the breaker will reduce O&M requirements, improve performance, and provide consistent, reliable operation across it’s lifetime.
Lifting Provisions
- 1.06” diameter holes
- 4 lifting locations points welded to the roof
Bushings
- 15.5kV, 125kV BIL, Porcelain
- Extra Creep: 25.2″ Top, 18.3″ Bottom
- 1250A: 1 1/4″ – 12 threaded stud
- 2000A: 2 1/4″ – 12 threaded stud
NEMA 2-Hole Ground Pads
- 6 exterior grounding locations
- Roof: Welded, Aluminum
- Enclosure: Welded, Stainless Steel
Instrument Panel (Optional)
Swing open from left or right side
34.25” x 28.00”
The Advantage
In today’s challenging market, the OD3Mag™ offers an opportunity to improve system reliability, faster restoration times and better customer satisfaction.
OD3MAG Design Advantages
- Position Indicators for each pole
- Operation counter can be viewed from outside
- Minimum enclosure penetrations prevent water intrusion
- The welded roof design transfers weight of bushings and CTs to the cabinet side panels thereby reducing roof deflection and reducing water leakage issues
- Innovative gasket system ensures sealing around bushing entrance points under moments of flex from external forces
- Stainless steel door hanger on high voltage cabinet creates automatic grounding point and increases safety during removal and replacement of the door
- Optional Forklift provisions allow more convenient handling and installation of the breaker on site
- Helps utilities improve their SAIDI and SAIFI scores
- Robust cabinet design requires no visual inspections outside of 5 year recommended maintenance cycle
Advantages of Magnetic Actuation
- No lubrication or regular maintenance requirements on the actuator
- Direct drive of push rods eliminates structural torquing of break drive components
- Consistent operating time of the mechanism across entire rated temperature range and min/max operating voltages of the breaker
- Rare earth magnets lose <1 % of flux density over time, requiring no adjustments throughout breaker lifetime
- Actuator controls are self-monitoring and report breaker status at all times
- Quieter actuation compared to traditional spring-spring mechanism
