Tropicalization Compact
®
NS circuit breakers comply with NF C 63-100 standard level 2 conditions (95% relative
humidity at 45° C or 80% at 55° C, hot and humid climate conditions). The materials used in Compact
NS circuit breakers will not support the growth of fungus or mold.
They also comply with the following standards:
• IEC 68-2-30 damp heat
• IEC 68-2-2 dry heat
• IEC 68-2-11 salt spray
• IEC 68-2-1 low temperatures
Pollution Degree Compact NS circuit breakers are certified for operation in pollution degree III environments as defined
by IEC standard 947 (industrial environments).
Environmental
Protection
Compact NS circuit breakers take into account concerns for environmental protection. Most
components are recyclable and parts are marked as specified in applicable standards.
Suitability for
Isolation (Positive
Contact Indication)
All Compact NS circuit breakers and switches are suitable for isolation as defined in the IEC 947-2
Standard:
• The isolation position corresponds to the O (OFF position).
• The operating handle cannot indicate the OFF position unless the contacts are open.
• Padlocks may not be installed unless the contacts are open
Installation of a rotary handle or a motor mechanism does not alter the functionality of the position
indication system.
The isolation function is certified by tests guaranteeing:
• The mechanical reliability of the position indication system
• The absence of leakage currents
• Overvoltage withstand capacity between upstream and downstream connections
Installation in
Class II
Switchboards
All Compact NS circuit breakers, even when fitted with a rotary handle or a motor mechanism, can be
installed through the door of Class II IEC switchboards (as per IEC 664 Standard). Refer to circuit
breaker installation instructions prior to installing circuit breaker.
Installation requires no special insulation because Compact NS circuit breakers provide Class II
insulation between the front face and all internal circuits.
