nVent RAYCHEM NGC-40-SLIM limiters are used for temperature limiting of
electrical heaters in industrial and potentially explosive atmospheres. The
RAYCHEM NGC-40-SLIM is a safety temperature limiter. RAYCHEM NGC-40-SLIM
units are approved for use in non-hazardous areas. Where needed the temperature
sensor of the unit can be placed in Zone 1, Zone 2, Zone 21 and Zone 22 when the
sensor is hazardous area approved.
1�8 Safety instructions
During operation, do not leave this Instruction Manual or other objects inside
the enclosure. Use the limiter only for its intended purpose and operate it only in
