RT16-00C NH00C 40A gG fuse

This ceramic square tube fuse provides line protection for industrial and commercial circuits. It carries a 40 A gG rating and operates at 500/690 V with a 100/50 kA breaking capacity. The knife shaped contact ensures reliable insertion into compatible fuse bases. Suitable for new installations or direct replacement in existing switchgear.

Installers needing 40 A gG protection at 500/690 V

This fuse suits electricians and maintenance teams specifying NH00C size devices for general purpose line protection. It is not intended for applications requiring a different current rating, voltage class or breaking capacity. Buyers who need a smaller or larger frame size must select an alternative series.

40 A gG rating at 500/690 V

The 40 A gG characteristic defines the overload and short-circuit response for cables and conductors. The 500/690 V rating sets the maximum system voltage. The 100/50 kA breaking capacity confirms the fuse can interrupt high fault currents safely. These three figures together determine whether the device matches the circuit design.

Questions about this item

What fuse holder or base accepts the NH00C size and knife-shaped contact of this 40 A gG fuse?

This fuse is built to the NH00C form factor with knife-shaped contacts, so it fits standard NH00C fuse bases or disconnectors rated for 500/690 V.

How is the RT16-00C fuse installed, and what common error should be avoided?

Switch off the circuit, remove the old fuse, and press the new fuse firmly into the NH00C base until the knife contacts seat fully; the frequent mistake is leaving a gap that creates resistance and heat.

When should this 40 A gG ceramic fuse be replaced after a fault?

Replace it after any over-current event that causes it to blow — the ceramic body and 100/50 kA breaking capacity are single-use, so a new fuse is required to restore protection.
