Accessories

Series G breakers are available with a comprehensive range of
accessories, including shunt trips, undervoltage releases, alarm
lockout and auxiliary switches, multi-wire lug kits, control wire
terminal kits, etc., that are field installable.

Plug-in blocks

Plug-in adapters simplify installation and front removal of circuit
breakers. Plug-ins are available for rear connection applications on
three- and four-pole circuit breakers. Trip-on drawout interlock kits
are included. Stabs for EG, JG and LG plug-ins rotate 90° for flexible
installation. Use terminal shields for IP30 protection.

Flex ShaftE handle mechanism

Flex Shaft handle mechanisms
make installing and operating
enclosure-mounted breakers
easier than ever. Installation and
adjustment of this flange­mounted mechanism can be
accomplished in about 10
minutes or less. Optional early
break auxiliary switch handle is
available. Use for Type 1, 12, 4
and 4X environments.

High-performance handle
mechanism

In addition to its robust design
features, the handle mechanism
has stand-off support that allows
