How many Micrologic A, P or H trip units can be supplied with an auxiliary power supply 24 VDC ?
That depends on the power supply. The trip unit requires 100 mA @ 24 Vdc.
So a 5 VA power supply @ 24 V (5 VA / 24V = 0.208 A) could supply two trip units.
The Phoenix power supply provided with Columbia switchboards has an output of 2.5 A, and could feed as many as 25 trip units.
