4. 5 Circuit Breakers
All panels utilize two-pole, thermal magnetic cir-
cuit breakers. Panels ordered with selective
coordination may include an electronic trip ele-
ment added to the primary and/or secondary
main circuit breakers to achieve 0.1 second sys-
tem coordination.
The primary and secondary (where applicable)
main circuit breakers are sized to protect the
transformer coil. The primary main circuit
breaker is sized at 125% of rated current. Any
supplied secondary main circuit breakers are
sized at rated coil ampacity.
The quantity and rating of branch circuit breakers varies by panel:
• MIP and MIE series: Provided with sixteen (16) factory-installed 20 A
branch circuit breakers (unless otherwise stated).
• MIC series: Quantity and ampacity of branch circuit breakers is provided
according to project documents. The maximum allowed is twelve (12).
The logic for simultaneously energized branch circuits is configured at the
factory per project specifications.
• MID series: Output voltage 1 (designated as the “low side”) is provided
with sixteen (16) factory-installed branch circuit breakers. Output voltage
2 (designated as the “high side”) is provided with either one (1) or two (2)
factory-installed branch circuit breakers. Ampacity is per project specifica-
tions
NOTE: To maintain compliance with UL 1047, branch
breakers must not exceed 60 A.
