Schneider Electric A9V44363 Vigi iC60 3P 63 A 300 mA
Description
A9V44363: Vigi iC60 3P 63 A 300 mA add-on block
The A9V44363 is a Schneider Electric Acti9 Vigi iC60 add-on residual current device in a three-pole version, rated 63 A with 300 mA sensitivity and Type AC detection. It is not a stand-alone breaker. It is clipped to the side of a compatible iC60 miniature circuit-breaker and joined to it by screws, so the breaker keeps its overload and short-circuit duty while the block supplies the earth-leakage function. Seven Star LLC supplies the A9V44363 in Oman and the GCC as an independent supplier based in Muscat.
Reading the title of A9V44363: 3P is the number of poles, 63A is the rated current, 300mA is the leakage threshold and AC type is the waveform class. The datasheet places the device in the outgoer position of a board, with voltage-independent tripping and a trip indicator on the front. It is a natural match for a three-phase load without a neutral conductor, such as a motor feeder or a heater bank, which is the pole count this reference is built around.
Use in Oman and the GCC
Boards in Oman and the wider GCC work in high ambient temperatures, with dust in desert sites and humidity near the coast. The datasheet gives A9V44363 an operating range up to 60 °C, and IP20 protection that rises to IP40 inside a modular enclosure, so the enclosure and its ventilation decide how the block behaves in service. Typical places for a 300 mA block include building services boards, pump stations, workshop feeders and temporary construction supplies, where a leakage threshold for fire risk is wanted in addition to the breaker.

Selection checklist and RFQ details for A9V44363
- Confirm the pole count of the breaker you will pair it with: it must be 3.
- Check that the breaker current is not above the 63 A limit for single terminal iC60 breakers.
- Decide whether 300 mA is the correct sensitivity for the earthing system and the risk being managed.
- Confirm that Type AC suits the loads, or choose a different type for electronic loads.
- Compare the mm width and 91 mm height with the enclosure.
- Check ambient temperature against the -5 to 60 °C operating range.
How the A9V44363 protects: residual current basics
A residual current device compares the current leaving through the live conductors with the current returning. If the difference exceeds the threshold, some current is leaving by another route, typically through an insulation fault to earth or a person, and the device opens the circuit. The this unit uses a 300 mA threshold with no deliberate delay, and the datasheet describes its tripping as independent of the supply voltage.
A 300 mA setting is a level normally chosen to limit fire risk and equipment damage on a feeder, not to protect people from direct contact, which is the job of a 30 mA device. In a graded design the block may sit upstream of finer devices on the final circuits, but the grading and the delay needed for selectivity must be worked out in the design. Type AC covers sinusoidal residual current, so loads that can create pulsating DC leakage need a different type.
Where the A9V44363 suits upper-range outgoers, small workshop or plant feeders
Because the block is 63 A, it is most often found on upper-range outgoers, small workshop or plant feeders. On three-phase equipment without a neutral, such as small motors and resistive heating, it provides earth-leakage monitoring in a compact three-pole stack. The mm width is the figure to check against the free space on the rail.
Terminals accept up to 35 mm² rigid and 25 mm² flexible conductors, so heavier cable can be landed without reducing.
Installation and testing of A9V44363
Mount the paired breaker on the DIN rail, clip the block on and tighten the screw connection between the two. The bottom terminals take a 14 mm strip length and a tightening torque of 3.5 N.m, which should be applied with a calibrated driver. The datasheet lists a trip indicator on the front, and the visual state helps when you inspect a board after a fault.
After installation, operate the device with the local test arrangement and record the result in the commissioning file. A residual current device that has not been exercised is an unknown quantity. Periodic checking by the operator is a normal part of maintenance, and the interval should follow the site procedure.
Breaker pairing for the A9V44363
The datasheet lists compatibility with the Acti9 iC60 miniature circuit-breaker and the Reflex iC60 integrated control circuit breaker, with a current ceiling per breaker family. For this 63 A block those ceilings are single terminal iC60 breakers up to 63 A, Disbo iC60N/H breakers up to 63 A, iC60L MA breakers up to 40 A and Reflex iC60 integrated control breakers up to 63 A. The block must be paired with a breaker that has the same pole count, so a three-pole breaker is required for this unit. A comb busbar can be used at the bottom of the assembly according to the datasheet.
Do not size the pair only by the block rating. The thermal and magnetic characteristic belongs to the breaker, the leakage characteristic belongs to the block, and both have to suit the cable and the load. Check the breaker catalogue number against the ceiling list before ordering.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running.
