Circuit Breakers — Product Installation Information
Product Description
Thomas & Betts circuit breakers are molded of a durable thermoset
plastic which is not subject to dielectric breakdown after arcing.
Operating handles are non-breakable plastic. Cases are color coded to
indicate the interrupting capacity of the breaker.
Both Type A, 1/2" per pole, and Type TB, 1" per pole, modules contain
thermal-magnetic trip units which provide fast magnetic-trip protection
against short circuits and time-delay-trip protection against overloads.
The unique side-clip design of Type A 2-pole breakers allows a true
common-trip 120/240 volt device that can be installed in a 1" mounting
space. Factory calibration after assembly assures consistent
performance when installed.

Operating Mechanisms
Breakers are supplied with quick-make, quick-break trip-free
mechanisms, which make it impossible to hold the breaker in the “On”
position against a fault or overload. When the handle is in the “Tripped”
position, midway between “On" and “Off”, it identifies a tripped condition.
Reset the breaker simply by moving the handle to the “Off” position, then
“On”. Factory-assembled two-pole breakers are common trip—one fault
trips all. Movable contact wiping action helps keep contact surfaces
clean when the breaker is operated mechanically. Arc chutes extinguish
arcs on short-circuit interruption and minimize ionized gases, while
exhaust vents guide gases harmlessly into the wiring gutter. Each pole is
individually tested, calibrated and sealed to retain its setting.
