Schneider Electric GVAD0110 TeSys GV2/GV3 1 NO + 1 NC Contact

GVAD0110: 1 NO plus 1 NC block with a normally closed fault contact

The GVAD0110 is a Schneider Electric auxiliary contact for the TeSys GV2 and GV3 motor circuit-breakers, with one normally open and one normally closed contact and a fault signal on a normally closed contact. It clips onto the left side of the breaker and carries state information to the control system. Seven Star LLC supplies the GVAD0110 in Oman and the GCC as an independent supplier based in Muscat.

The four GVAD references on the market differ in which contact is the fault contact and whether it is NO or NC. For the GVAD0110 the datasheet says auxiliary contacts operation is a fault signal on 1 NC, and the pole composition is 1 NO + 1 NC. The pairing is typical for a fail-safe control circuit that monitors a healthy loop.

Technical specifications of the GVAD0110

Compatibility and ratings of the GVAD0110

The compatibility list in the datasheet is GV2ME, GV2P, GV2L, GV2LE, GV2RT, GV3L and GV3P. The block fits the left side, which means no other left-hand accessory can be used at the same position.

It is rated for 48 to 690 V AC and 24 to 240 V DC, with a thermal current of 6 A and 2.5 A on the fault contact. For logic-level signals the minimum is 5 mA and 17 V, so very small PLC inputs need a check against that threshold.

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.

How the fault contact of the GVAD0110 is used

A normally closed fault contact is a monitored loop: as long as the breaker is healthy the loop is closed, and an open circuit, whether from a trip or a broken wire, is read as an alarm. That is why safety-minded designs ask for the NC type.

The second contact, normally open, gives a plain run or closed indication. With both in one block, a single accessory feeds a motor-status lamp and an alarm input of a PLC from the same breaker.

GVAD family: the GVAD0110 against its siblings

The four references below share the same left-side mounting and ratings and differ only in contact pattern and lifecycle status.

Specifying the GVAD0110 correctly

• Contacts: 1 NO + 1 NC, fault signal on the NC.
• Breaker: one of the listed GV2 or GV3 families.
• Control circuit: voltage within 24 to 240 V DC or 48 to 690 V AC, current within 6 A.
• Alternatives: GVAD1001 puts the fault signal on a NO contact, and GVAD1010 gives two NO contacts.
• Document the contact meaning in your wiring schedule, because the datasheet label and the physical block carry only the code.

Wiring and verification of the GVAD0110

After isolating the breaker, push the block into the side seat, wire the terminals and verify continuity in the closed and tripped positions with a meter before restoring power. The block has a net weight of 0.055 kg.

Record the result in the commissioning sheet. A normally closed fault loop should read closed with the breaker on and open when tripped; if the readings are reversed, the wrong variant has been installed.

GVAD0110 uses in Oman and the GCC

Motor feeders for pumps, fans and conveyors in utilities and process plants use GV2 breakers with contact blocks to report status to a PLC or a DCS. The normally closed fault loop is common in oil and gas skids where wire breaks must raise an alarm.

Heat inside the starter panel is the main environmental stress in the region; the datasheet lists a normal environment rating, so keep the cabinet ventilated.
