Section 1: General information
Front-mounted standard terminal block kits are
available for standard frame fix-mounted circuit
breakers, as well as certain standard frame
drawout cassettes.
Kits 2A10885G36–G33 add front-mounted
terminals to three-pole breakers (IEC), and
three-pole cassettes (IEC only). G36 is used
on 800–1250A units, G32 on 1600–2500A units,
and G33 on 3200A units.
Kits 2A10885G46–G43 add front-mounted
terminals to four-pole breakers (IEC), and four-pole
cassettes (IEC only). G46 is used on 800–1250A
units, G42 on 1600–2500A units, and G43 on
3200A units.
Two front-mounted terminal kits are required for
IZM63 and IZM99 breakers 4000–6300A.
