General characteristics for NFPA handle

The GMX61 NFPA lever handle complies with the
requirements of the North American NFPA79 standard.
This standard requires that the switch disconnector can be
operated without accessories or tools whether the door is
closed or open. In case of operation with an open door, a
device is integrated into the GMX61 NFPA handle to prevent
it from being activated unless a voluntary action is taken to
unlock it.

Certifications and compliance

Certifications obtained: cURus for GMX61 NFPA.
Compliant with standards: IEC/EN 60947-1, IEC/EN 60947-3.
