Class 9421 Type L Circuit Breaker Mechanisms
Type L door-mounted, variable-depth operating mechanisms feature heavy duty, all metal construction
with trip indication. All can be padlocked in the “OFF” position when the enclosure door is open. Further,
the handle assemblies can be locked “OFF” with up to three padlocks, which also locks the door closed.
(The 3" handle accepts one padlock.)
Complete Kits
Complete kits are rated for NEMA Type 1, 3R and 12 enclosures, and a door-drilling template is supplied to
ease installation. They include a handle assembly, operating mechanism, and shaft assembly.
q Mounting depth measured from circuit breaker mounting surface (control panel) to outside of enclosure door in inches.
j Types LT1, LT4, LX1, and LX4 include an 8” handle rather than a 6” handle.
Component Parts
Component parts kits are rated for NEMA Type 1, 3, 3R, 4, 4X, and 12 enclosures. All handle assemblies
are painted (the handle is flat black and the base ring is silver).
c Mounting depth measured from circuit breaker mounting surface (control panel) to outside of enclosure door in inches.
NEMA Type 3 and 4 Handle Assemblies
t Due to gasketing, NEMA Type 3 & 4 handle assemblies are NOT trip indicating.
