Square D

400 A single meter main

combination service entrance devices

Markets requiring a single main disconnect now have meter main

solutions that complement the current Square D 400 A dual main

products. The 400 A single meter main is available in three meter

socket congurations, including a Class 320 with manual (link)

bypass, Class 320 lever bypass and a K-base conguration.

The Square D 400 A, 120/240 Vac, single phase, three-wine

meter main product line utilizes a single 400 A maximum main

circuit breaker.

The factory-installed 400 A “DG” main circuit breaker service

disconnect has dual load terminations per phase, which can feed

a downstream 400 A panelboard or dual load centers based on

product application requirements. In addition, the device

accommodates an optional circuit breaker mounting kit for eld-

installation of two Q-Frame (200 A maximum) branch circuit breakers

used as mains for two downstream load centers. These devices have

short circuit current ratings for use on systems up to 65 k AIC.

The Type 3R enclosure’s design is ideal for surface mounting,

underground feed or overhead feed with an optional overhead feed

trough. The device can be eld-converted for semi-ush underground

service applications using the ange mounting kit, which offers three

mounting depth options.
