FOR CURRENT INFORMATION
Special Magnetic or Thermal Calibration (20% Price Adder)
Magnetic:
The magnetic trip ranges for standard circuit breakers are listed in the Square D Digest. Requirements outside this range are best accommodated by
selecting another standard circuit breaker. In some cases where this is not practical, a circuit breaker may be ordered with special magnetic calibration.
Special magnetic calibration is not possible in all cases. Circuit breakers with special magnetic calibration and an adjustable magnetic trip range are not
UL Listed; those with a fixed magnetic trip setting are UL Listed. Consult Square D/Schneider Electric sales office for more information.
50 Degrees C:
UL 489 Listed molded case circuit breakers are calibrated for 40 degree C ambient temperature. To meet requirements of higher ambient conditions,
circuit breakers can be factory calibrated for a 50 degree C ambient temperature. Circuit breakers with special thermal calibration are not UL Listed. To
order, place the suffix "35" after the catalog number (e.g., KAL36225-35). No other special thermal calibrations are available.
Visi-blade Circuit Breakers (20% Price Adder)
Visi-blade construction is a modification to the cover of a thermalmagnetic circuit breaker, a molded case switch, or a MAG-GARD® circuit
breaker which provides a "window" through which the position of the
movable contacts can be verified. Luminescent paint is applied to the
movable contact arms to clearly indicate their position. Gases produced
during high level interruption may cause clouding of the Visi-blade
window. Visi-blade circuit breakers listed below are UL Listed except for
FH circuit breakers. Visi-blade construction is not available on circuit
breakers not included in table below.
Add suffix letter 'V to the circuit breaker catalog number, i.e., FAL
36100V.

Moisture and Fungus Resistant Treatment for Circuit Breakers (20% Price Adder)
This treatment covers the application of moisture and fungus resistant varnish to circuit breakers and molded case switches.
• The varnish meets Military Specification MIL-V-173C VARNISH, MOISTURE AND FUNGUS RESISTANT.
• The treatment meets military Specification MIL-T-152E TREATMENT, MOISTURE AND FUNGUS-RESISTANT, OF COMMUNICATIONS, ELECTRONIC, AND ASSOCIATED ELECTRICAL EQUIPMENT.
The treatment of circuit breakers in accordance with said specifications is intended to protect them against the moisture and fungus condition encountered in service by retarding the absorption of moisture and inhibiting the growth of fungi.
To order, place the suffix "FT" at the end of the circuit breaker catalog number, e.g., FAL36100 becomes FAL36100FT.
This treatment is not available on KD circuit breakers.
EDB, FDA, and GJL circuit breakers are inherently fungus resistant and need no further treatment.
Short Handle for LA/LH Circuit Breakers (No Additional Charge)
Certain applications of the LA/LH circuit breakers (as mains in particular panelboards) require the use of a slightly shorter operating handle. For ordering
information refer to the chart below.
