Mersen FR22GG69V32 Ferrule Fuse 22×58 gG 32A 690V F212594

FR22GG69V32 (item number F212594) is a Mersen cylindrical ferrule fuse-link, size 22 x 58 mm, type gG, rated 32 A at 690 V ac / 250 V dc with 120 kA ac and 100 kA dc breaking capacity. It has a ceramic body, silver-plated copper contacts, dissipates 3.7 W at rated current and weighs 54 g.

The 690 V cylinder fuse for motor feeders

The 22 x 58 mm size is the largest cylindrical fuse in the common 10, 14 and 22 mm series, with a range of 2 to 125 A in the Mersen datasheet and voltage ratings of 500 to 690 V ac. Up to 80 A the listed items are rated 690 V; the 100 A and 125 A items are 500 V. The 32 A item is therefore in the 690 V part of the range, making it suitable for 400/690 V motor and feeder circuits.

Mersen states that all cylindrical fuse-links have ceramic bodies and silver-plated contacts, and that the 14 x 51 and 22 x 58 sizes are available with an optional striker to activate an auxiliary contact; the striker range appears separately in the datasheet. This item is the version without striker.

Selection and ordering guide

Catalog number decoding: FR22 (22 x 58 mm) GG (gG) 69V (690 V) 32 (32 A). Neighbours are FR22GG69V25 (25 A) and FR22GG69V40 (40 A). Choose a striker version if you need an auxiliary contact to signal a blown fuse.

Match the fuse holder to 22 x 58 mm and 690 V; many holders for this size are rated to 690 V but some are lower, so check the holder datasheet.

Within the 690 V ratings of the 22 x 58 mm series the datasheet dissipation rises from 0.9 W at 2 A to 7.4 W at 80 A; the 32 A item at 3.7 W is mid-range. The body weight of 54 g is the same for all ratings, so a holder suited to 22 x 58 fits them all, but its current rating must not be below the fuse-link rating chosen.

Installation and operation notes

Insert into a 22 x 58 holder or fuse-switch; check the holder current rating is not below 32 A.

Dissipation of 3.7 W per fuse; 11.1 W for three poles (derived) adds to the enclosure heat load.

Derived check: at 690 V three-phase, 32 A corresponds to about 38 kVA (square root of 3 x 690 V x 32 A). Motor starting current should be checked against the gG time-current curve in the datasheet, or an aM fuse selected instead, since a gG fuse sized for a motor can be larger than the cable needs.

Applications in Oman and the GCC

Motor branch circuits, pumps, compressors, cooling fans and process-skid feeders on 400/690 V systems in oil and gas, petrochemical, water and industrial plants; panels built to IEC practice commonly use cylindrical fuses in fuse disconnectors.

For motor starting currents consider aM fuse-links from the same Mersen ranges.

Ordering tip: the Mersen item number F212594 identifies this 32 A fuse-link, and neighbouring ratings use their own numbers (for example FR22GG69V25 is N212072 and FR22GG69V50 is P214626). Order fuse-links in sets of three for a three-phase circuit and keep spares of the same rating and voltage.

Selection and handling notes

The 22 x 58 mm body needs a holder or fuse disconnector sized for that cylinder and rated for 690 V. At 32 A the fuse dissipates 3.7 W, so allow space and ventilation in the enclosure when many are fitted side by side. Where a blown-fuse signal is needed, choose the striker version listed separately in the datasheet instead of this plain item.
