Vibration
PowerPact H-, J-, and L-frame devices resist mechanical vibration.
Tests are carried out in compliance with standard UL 489 SA and SB for the levels required by
merchant-marine inspection organizations (Veritas
®
, Lloyd's
®
, etc.):
PowerPact H-, J-, and L-frame circuit breaker meet IEC 60068-2-6 for vibration:
— 2.0 to 25.0 Hz and amplitude +/- 1.6 mm
— 25.0 to 100 Hz acceleration +/- 4.0 g
Excessive vibration may cause tripping, breaks in connections or damage to mechanical parts.
Electromagnetic Disturbances
PowerPact H-, J-, and L-frame devices are protected against:
•
overvoltages caused by circuit switching
•
overvoltages caused by an atmospheric disturbances or by a distribution-system outage (such as
from failure due to lightning)
•
devices emitting radio waves (radios, walkie-talkies, radar, etc.)
•
electrostatic discharges produced directly by users
PowerPact H-, J-, and L-frame devices have successfully passed the electromagnetic-compatibility
tests (EMC) defined by the following international standards:
•
IEC/EN 60947-2: Low-voltage switchgear and controlgear, part 2: Circuit breakers:
— Annex F: Immunity tests for circuit breakers with electronic protection
— Annex B: Immunity tests for residual current protection
•
IEC/EN 61000-4-2: Electrostatic-discharge immunity tests
•
IEC/EN 61000-4-3: Radiated, radio-frequency, electromagnetic-field immunity tests
•
IEC/EN 61000-4-4: Electrical fast transient/burst immunity tests
•
IEC/EN 61000-4-5: Surge immunity tests
•
IEC/EN 61000-4-6: Immunity tests for conducted disturbances induced by radio frequency fields
•
CISPR 11: Limits and methods of measurement of electromagnetic disturbance characteristics of
industrial, scientific and medical (ISM) radio-frequency equipment.
These tests ensure that:
•
no nuisance tripping occurs due to electromagnetic disturbances
•
tripping times are respected
Tropicalization
The materials used in PowerPact circuit breakers will not support the growth of fungus and mold.
PowerPact circuit breakers have passed the test defined below for extreme atmospheric conditions.
Dry cold and dry heat:
— IEC 68-2-1–dry cold at -55°C
— IEC 68-2-2–dry heat at +85°C
Damp heat (tropicalization)
— IEC 68-2-30–damp heat (temperature + 55°C and relative humidity of 95%)
— IEC 68-2-52 level 2–salt mist
