Tropicalization

Circuit breakers and accessories in the ABB SACE family of

molded case circuit breakers have been tested in compliance

with the IEC 60068-2-30 Standard, carrying out two cycles at

131 °F (55 °C) with the “variant 1” method (clause 6.3.3). The

suitability of their use under the most severe environmental

conditions is therefore ensured with the hot-humid climate

defined in climatograph 8 of the IEC 60721-2-1 Standards thanks

to:– insulating cases made of synthetic resins reinforced with glass

fibers;– anti-corrosion treatment of the main metallic parts (ambient

C UNI 3564-65);– Fe/Zn 12 galvanization (UNI ISO 2081), protected by a conver

sion layer mainly consisting of chromates (UNI ISO 4520).

The electronic PR211/P, PR212/P and PR221DS

microprocessor-based overcurrent releases do

not undergo any variations in performance as the

temperature varies but, in the case of tempera

tures exceeding 104 °F (40 °C), the maximum setting for protection against overloads, L, must be

reduced, as indicated in the derating graphs on page 3/28. to take into account the heating phe

nomena which occur in the copper parts of the circuit breaker passed through by the phase current.

For temperature above 158 °F (70 °C) the circuit breaker performances are not guaranteed.

Electromagnetic compatibility

With the use of the SACE PR211/P, PR212/P and PR221DS

electronic microprocessor-based releases and the SACE RC211.

RC212. RC221 and RC222 electronic residual current releases,

operation of the protections is guaranteed in the presence of inter

ferences caused by electronic apparatus, atmospheric distur

bances or electrical discharges. No interference with other

electronic apparatus near the place of installation is generated

either. This is in compliance with the IEC 60947-2 Appendix F

Standards and European Directive No. 89/336 regarding EMC

electromagnetic compatibility.
