OD3MAG Outdoor Substation Breaker
The JST Power Equipment OD3MAG is a 15.5 kV outdoor substation circuit breaker with recloser functionality for utility substations and solar and wind distribution, sold and supported in Texas and Oklahoma and on data center projects nationwide by Ryan Sales.
- 15.5 kV max
- 1250 A / 2000 A
- 31.5 kA sym / 43 kA asym
- 82 kA peak withstand
- BIL 125 kV
Overview
The OD3MAG is billed as the first medium voltage substation breaker with configurable single-phase or three-phase operation, blending the ratings and durability of a circuit breaker with the functionality of a recloser. Rated 15.5 kV, 1250/2000 A, 31.5 kA symmetrical with 125 kV BIL and 3-cycle interruption, it uses field-proven magnetic actuation with independent pole actuators in a NEMA 4 / IP55 enclosure rated -40 to +50 C. A welded roof, lift-out breaker design, and swing-door control panel simplify maintenance in utility yards.
