Schneider Electric GVAD1001 TeSys GV2/GV3 1 NC + 1 NO Contact

GVAD1001: 1 NO plus 1 NC block with a normally open fault contact

The GVAD1001 is a Schneider Electric TeSys Deca auxiliary contact for GV2 and GV3 motor circuit-breakers. Like the GVAD0110 it holds one normally open and one normally closed contact, but the fault signal sits on a normally open contact, which is what the datasheet states as fault signal 1 NO. Seven Star LLC supplies the GVAD1001 in Oman and the GCC as an independent supplier based in Muscat.

The practical difference from the GVAD0110 is one of logic. A normally open fault contact closes when the breaker trips, which suits an alarm lamp, a buzzer or a PLC input that is read as true during a fault. A normally closed fault contact does the opposite.

Technical specifications of the GVAD1001

Choosing the NO fault logic of the GVAD1001

Alarm systems fall into two schools. In an energise-to-alarm design the fault contact closes and drives a lamp or a horn directly, which is easy to understand and to test. In a de-energise-to-alarm design the contact opens and the system is supervised against wire breaks. The GVAD1001 serves the first school and the GVAD0110 the second.

Check what your PLC input card or annunciator expects before ordering, because swapping a block later means reopening the panel and re-lettering the terminals.

GVAD1001 selection notes

• Confirm that the fault circuit is meant to close on a trip.
• Check that the second contact, normally closed, matches the status function required.
• Confirm the breaker family against the compatibility list.
• Review the 17 V and 5 mA minimum for low-level inputs.
• Compare with GVAD1010 if two normally open contacts are wanted.

Mounting and electrical ratings of the GVAD1001

The block clips on the left flank of GV2ME, GV2P, GV2L, GV2LE, GV2RT, GV3L and GV3P breakers, as listed in the datasheet. It measures 9.3 mm by 89 mm by 66 mm.

The thermal current is 6 A, the fault contact is rated 2.5 A, and the voltage ranges are 48 to 690 V AC and 24 to 240 V DC. The minimum switching values of 5 mA and 17 V mean that a low-level electronic input is acceptable only above that level.

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.

GVAD1001 applications in Oman and the GCC

Alarm annunciators on pump houses, camp utilities and small process skids typically collect trip signals as closing contacts. The GVAD1001 gives the NO fault contact to feed those channels and a NC contact to show that the breaker is on.

The same arrangement is common on HVAC plant rooms in malls and hospitals, where a BMS counts trips as digital inputs.

Installing the GVAD1001

Isolate and open the breaker, seat the block on the left side, tighten the terminals and label each wire. Test the fault contact by tripping the breaker with its standard test method and observing that the circuit closes.

Any spare breaker panels in a stock room should have the contact block fitted only after the control wiring is confirmed. Adding it later is simple, but the label on the block is the only reminder of its logic.
