Schneider Electric C4036E400 MicroLogic 6.3 E Trip Unit 400 A
Description
C4036E400: MicroLogic 6.3 E trip unit, 400 A, three poles
The C4036E400 is a MicroLogic 6.3 E electronic trip unit rated 400 A at 40 °C, three poles with three protected poles, for ComPacT circuit breaker frames. The datasheet range compatibility entry is ComPacT NSX400 and ComPacT NSX630. Seven Star LLC supplies the C4036E400 in Oman and the GCC as an independent supplier based in Muscat.
It is the LSIG unit of its family: long-time, short-time, instantaneous and ground-fault protection, with an LCD display and an energy meter function. The datasheet has no breaking capacity because the breaking capacity belongs to the frame the unit is fitted to.
Fitting and compatibility of the C4036E400
The datasheet range compatibility is ComPacT NSX400 and ComPacT NSX630, so the C4036E400 is intended for those ComPacT frames; the rating 400 A at 40 °C is fixed to this unit. The trip unit is fitted to a basic frame; the frame sets the breaking capacity.
Frames in this group of datasheets include C40F3, C40F4, C40H4, C40N3. The companion trip unit reference C6336E630 covers the 630 A rating.
Operating range of the C4036E400 in Oman and the GCC
The datasheet lists -25 to 70 °C for operation and -40 to 85 °C for storage, with protection IP40 conforming to IEC 60529 and a standard of EN/IEC 60947-2. For Oman, the relevant check is the temperature inside the board in summer, because the rating on this datasheet is tied to a reference temperature of 40 °C.
Typical uses are main and sub-main boards for water plants, industrial processes, substations and large buildings where ground-fault protection and metering are specified.

Protection stages of the C4036E400
Long-time protection has an adjustable pick-up Ir of 160 to 400 A, with an adjustable delay: 15 to 400 s at 1.5 x Ir; 0.35 to 11 s at 7.2 x Ir; 0.5 to 16 s at 6 x Ir. Thermal memory is 20 minutes before and after tripping.
Short-time protection is adjustable from 1.5 to 10 x Ir, with a delay of 0 to 0.4 s with I²t off; 0.1 to 0.4 s with I²t on. Instantaneous protection is adjustable over 1.5 to 12 x In.
Ground-fault protection is adjustable too: Ig is 0.4 to 1 x In for In = 40 A and 0.2 to 1 x In for In > 40 A and the delay tg is 0 to 0.4 s with I²t off; 0.1 to 0.4 s with I²t on. The datasheet lists zone selective interlocking as available, which helps coordination between upstream and downstream boards.
Display, measurement and data of the C4036E400
The front has an LCD display and the measurement type on the datasheet is an energy meter. Local signalling comprises: Flashing LED (green) for ready to operate; LED 105 % Ir (red) for overload; LED 90 % Ir (orange) for overload.
The data the trip unit can communicate is listed as: energy metering; protection and alarm settings; time-stamped histories and event tables; instantaneous and demand values; maintenance indicators; demand current and power; power quality; maximeters/minimeters. Whether these values can be read by a supervisory system depends on the communication accessories chosen, which the datasheet for this reference does not describe.

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. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.

Ordering Schneider Electric products: what we need
Send the commercial reference from the label (for example LC1D18M7 or ATV320U22N4C). For breakers, confirm the rated current, number of poles, breaking capacity and trip unit. For contactors, give the coil voltage. For drives, give the motor power and supply voltage. APC products are listed on their own brand page.
