Interlocking of Circuit Breakers with Toggle Control
Two devices can be interlocked using this system. Two identical interlocking systems can be used to
interlock three devices installed side by side.
Authorized positions:
• one device closed (ON), the others open (OFF)
• all devices open (OFF)
The system is locked using one or two padlocks (shackle diameter 0.19–0.31 in. [5 to 8 mm]). This
system can be expanded to more than three devices.
There are two interlocking-system models:
• one for PowerPact H- and J-frame circuit breakers
• one for PowerPact L-frame circuit breakers
All toggle-controlled unit-mount or plug-in PowerPact H-, J-, and L-frame circuit breakers and
automatic switches of the same frame size can be interlocked. The devices must be either all unit-
mount or all plug-in versions. Interlocking is not available for I-Line constructions.
The toggle interlock system can receive one or two padlocks with diameters of 0.19–0.31 in. (5–8 mm).
Both interlocked circuit breakers must be unit-mount or both plug-in. Two sliding interlocking bars can
be used to interlock three circuit breakers installed side-by-side, in which case one circuit breaker is in
the ON (I) position and the two others in the OFF (O) position. (Kit S29354, not available for two-pole
HD and HG devices.)
Interlocking of Two Devices with Rotary Handles
Interlocking involves padlocking the rotary handles on two devices which may be either circuit breakers
or automatic switches.
Authorized positions:
• one device closed (ON), the other open (OFF)
• both devices open (OFF).
The system is locked using up to three padlocks (shackle diameter 0.19–0.31 in. [5 to 8 mm]).
There are two interlocking-system models:
• one for PowerPact H- and J-frame circuit breakers
• one for PowerPact L-frame circuit breakers
All rotary-handle unit-mount or plug-in PowerPact H-, J-, and L-frame circuit breakers and automatic
switches of the same frame size can be interlocked. The devices must be either all unit-mount or all
plug-in versions. Interlocking is not available for I-Line constructions
The rotary handles are padlocked with the devices in the OFF (I) position. The interlock mechanism
inhibits the two devices from being closed (ON/I) at the same time, but allows for both devices to be
open (OFF/O) simultaneously. (Kit S29369. Not available for two-pole HD and HG devices.)
