Schneider Electric GVAD1010 TeSys GV2/GV3 2 NO Contact Block

GVAD1010: two normally open contacts for breaker status and trip signals

The GVAD1010 is a Schneider Electric TeSys Deca side contact block for GV2 and GV3 motor circuit-breakers with two normally open contacts, one of which acts as the fault signal. It is the right accessory when the control system only needs closing signals and no normally closed loop. Seven Star LLC supplies the GVAD1010 in Oman and the GCC as an independent supplier based in Muscat.

Within the family, the GVAD1010 is the only active reference with two NO contacts. The other three trade one of them for a normally closed contact. So the choice is mostly about the input card that will read them.

Technical specifications of the GVAD1010

Ordering checklist for the GVAD1010

• Both contacts normally open; the fault signal is one of them.
• Match the PLC input type to closing signals.
• Check compatibility of the breaker with the listed GV2 and GV3 types.
• Check that the signal voltage is within 24 to 240 V DC or 48 to 690 V AC.
• Keep the contact function written on the wiring schedule.

GVAD family: the GVAD1010 against its siblings

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

What the GVAD1010 fits and how it is rated

The block mounts at the left of GV2ME, GV2P, GV2L, GV2LE, GV2RT, GV3L and GV3P breakers, as the datasheet states. With 9.3 mm width it keeps a row of breakers compact.

Electrical limits are the same as in the other family members: 6 A conventional thermal current, 2.5 A on the fault contact, 48 to 690 V AC, 24 to 240 V DC, and 5 mA and 17 V as minimum switching 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.

Commissioning notes for the GVAD1010

Fit with the feeder isolated, check continuity at each terminal pair in both breaker positions, and record which terminal is the fault contact and which is the status contact. The datasheet gives mechanical durability as 100000 cycles, so no extra maintenance is needed in ordinary use.

When replacing a block on a running plant, plan the shutdown of the feeder; the block cannot be changed live.

GVAD1010 in Oman and GCC installations

Packaged plant such as chiller skids, fire-water pump panels and compressor starters report their breaker status with closing contacts to the site DCS. Two NO contacts on one block save an extra accessory.

Where panels are built to a standard of closing signals, the GVAD1010 is the usual spare to hold in stock.

Reading the two contacts of the GVAD1010

With both contacts normally open, each one gives a closing signal. One reports the fault condition, the other reports the status of the breaker. Neither carries a supervised loop, so a broken cable shows up as a missing signal and not as an alarm.

If your design relies on loop supervision, specify a block with a normally closed fault contact. If it uses simple lamp or counter inputs, the GVAD1010 keeps the logic uniform: all signals are closing signals.

Information to send with an RFQ for the GVAD1010

• Full reference and quantity required
• Breaker model (GV2 or GV3 type) the block must fit
• Contact logic needed (NO or NC fault signal)
• Signal voltage and the input card that reads it
• Delivery location and timing

Storage, handling and spares for the GVAD1010

Keep the GVAD1010 in its original packaging in a dry, dust-free store until installation, and check the label against the order before fitting. For plants that run continuously, holding one spare unit on site shortens downtime if a replacement is needed during a shutdown or after a fault. Record the reference and installation date in the maintenance log so the next order can be placed quickly.
