Schneider Electric GVAD0101 TeSys GV2/GV3 2 NC Contact Block

GVAD0101: discontinued 2 NC side contact block for GV2 and GV3

The GVAD0101 is a Schneider Electric add-on auxiliary contact block for the TeSys Deca GV2 and GV3 motor circuit-breakers. The datasheet title describes it as one fault-signalling normally closed contact plus one normally closed contact, mounted on the side, for GV2 and GV3 except the GV3ME. Seven Star LLC supplies the GVAD0101 in Oman and the GCC as an independent supplier based in Muscat, and because the datasheet carries a discontinuation notice we position it as a spare for installed breakers.

It is the all-normally-closed version of the GVAD family: both contacts are NC, and the one that carries the fault role is also NC. That makes it unusual, since most indication circuits want a normally open contact for a lamp. A normally closed pair fits a loop that must open when the breaker moves.

Technical specifications of the GVAD0101

Lifecycle status of the GVAD0101

The datasheet header states Discontinued on 17 Jul 2023. Anyone who maintains panels built before that date should treat this reference as end-of-range: stocks are finite, and a replacement plan should be written down before the last breaker with this accessory fails.

The practical rule is simple. If the panel already has a GVAD0101, a like-for-like spare keeps the control wiring unchanged. If the panel is new, the active siblings in the same family, such as the GVAD0110, GVAD1001 and GVAD1010, are the sensible starting point, and we can compare the contact patterns with you.

Which breakers accept the GVAD0101

The datasheet compatibility list names the GV2ME, GV2P, GV2L, GV2LE, GV2RT, GV3L and GV3P families, while the title excludes the GV3ME. The block sits on the left flank of the breaker, so the left side must be free of another accessory.

Because the block is only 9.3 mm wide, it adds very little to the footprint of a breaker row. This is why add-on contacts of this style are chosen for compact motor starter feeders.

The block mounts on the left side of the breaker and is 9.3 mm wide, 89 mm high and 66 mm deep, with a net weight of 0.055 kg. The datasheet lists a rated operational voltage of 48 to 690 V AC and 24 to 240 V DC, a conventional thermal current of 6 A, and 2.5 A for the fault-signalling contact. Rated operational power at AC-15 is 720 VA at 230 to 240 V and 850 VA at 380 to 415 V, each with an electrical durability of 100000 cycles; the DC-13 figures include 120 W at 240 V DC.

GVAD0101 checks before ordering

• Confirm the contact pattern: 2 NC, with one of them the fault-signal contact.
• Confirm the breaker model is on the compatibility list and is not a GV3ME.
• Confirm that the signalling circuit stays inside 6 A thermal and 2.5 A fault limits.
• Ask whether the installed breaker is itself still current, since spare accessories are of little use on a stranded breaker.
• Check the minimum switching level: the datasheet gives 5 mA and 17 V for reliable operation.

Fitting and testing the GVAD0101 on site

Switch the breaker off and isolate the feeder first. The block clips to the side of the device and its terminals face the wiring duct, so a labelled ferrule on each wire helps later fault-finding.

After fitting, test both states: close the breaker, confirm the NC pair opens as the circuit requires, then trip it with the test method of the breaker and confirm the fault contact changes state. The mechanical durability is 100000 cycles, so a block that has been through many trip tests deserves attention.

GVAD0101 in Oman and GCC plants

Older motor starter panels at water pumping stations, desalination plants and industrial utilities often still carry GV2 breakers with this class of block. A failed contact block can leave a PLC reading a permanent fault, and a spare on the shelf is the quickest cure.

In dusty or hot panels, check the terminals at each planned shutdown, since screw terminals on auxiliary circuits are easy to forget.
