List MD: 23” 2-Row Distribution Cabinet with (39) Load Positions, (9) Battery Disconnect Positions, Low Voltage
Load Disconnect (LVLD) and Low Voltage Battery Disconnect (LVBD)
Features
♦
Single Voltage Distribution (-48V)
♦
Maximum Capacity:
600A @ +40°C;
400A @ +65°C
♦
Bottom Row: (9) Battery Disconnect Positions with LVBD
(15) Load Positions
♦
Top Row:
(24) Load Positions with LVLD
♦
Accepts TPS/TLS-Type Fuses (3 to 100A) or Bullet Nose Type Circuit Breakers (1 to 250A)
Caution: In a +40 °C ambient, 100 A circuit breakers can be used without a space provided the continuous current in
each device does not exceed 64 A. 100 A fuses, 150 A and 250 A circuit breakers do not require a space
adjacent to it.
At or above +65°C, the maximum size circuit breaker used shall be 125 A. The maximum size fuse used shall
be 70 A. Devices rated at 50 A or greater shall have an empty mounting position between it and any other
overcurrent protective device.
System contains a low-voltage load disconnect that disconnects the (24) load positions in the top row. It also
contains a low-voltage battery disconnect.
Restrictions
This Distribution Cabinet can be used in List 12, 13, 17, 22, 23 or 27 only.
The system is designed for a maximum of one (1) Distribution Cabinet. The Distribution Cabinet is assembled immediately
above the power shelf.
Adequate vertical mounting space must be provided above each Distribution Cabinet to accommodate distribution and
battery cabling.
Unless otherwise specified, fuses and/or circuit breakers are mounted from left to right for loads, and right to left for battery,
starting with the highest capacity and working to the lowest capacity.
Maximum size of wire to be connected to a single fuse holder or circuit breaker position is 2 AWG.
If battery disconnects are located outside the Distribution Cabinet, order (1) P/N 549019.
