Compact® NSF and NSJ 150 to 600 A Circuit Breakers

Section 2—General Characteristics

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

Environmental Protection

Suitability for Isolation (Positive Contact Indication)

Compact NS circuit breakers are certified for operation in pollution degree III environments as defined by IEC standard 947 (industrial environments).

Compact NS circuit breakers take into account concerns for environmental protection. Most components are recyclable and parts are marked as specified in applicable standards.

06153037

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.
