Rated Current

Use three numbers to print required current value

between .100 amps minimum and 30.0 amps maximum.

For example, use:

.100 or 2.00 or 10.0

Fourth Decision

Frequency and Delay

50/60Hz short delay

50/60Hz motor start

50/60Hz 125% instant trip

For addition of inertial delay, add an “F” to any

delay numeral. (Not available on units rated at

125VAC).

LEG DECISION TABLES

The ordering code for LEG circuit breakers may be

determined by following the decision steps in the tables

shown here.

The coding given permits a self-assigning part number

but with certain limitations. Special applications may

require a factory-assigned part number. Typical examples

are units with mixed ratings, combinations of styles, or

constructions not listed in the third decision table. With

these, it is suggested that order entry be by description

and/or drawings and a part number will be established.

Additionally, it is standard policy to establish a factory-

assigned part number whenever a descriptive drawing

exists to provide cross reference, traceability and

manufacturing control.

When specifying a circuit breaker for AC motor start

or high inrush applications, the peak amplitude and surge

duration should be specified for factory assistance in

rating selection.

For example, the following is the code for a single

pole, LEG screw type terminal, series unit with auxiliary

switch, designed for operation in a 50/60Hz circuit. It has

a short time delay, a rating of 20 amperes, a black marked

handle and is VDE approved.

To determine the ordering number for your particular LEG

unit, simply follow the steps shown. You may use this

number to place an order or as a reference for further

questions you may have.

Notes:

A. When “A” (metric thread mounting) is specified in the sixth

decision in combination with screw terminal option in the

second decision, metric screw terminals are supplied.

B. LEG, LEGH, LEGS, LEGHS, LEGZX and LEGBX circuit

breakers are designed to meet 8mm creepage and

clearance requirements for installation Category III,

Pollution Degree 3, Case A as measured in IEC 664.

Intended for use in equipment designed to comply with IEC

601 and 950 and VDE 0804 and 0805.
