Schneider Electric ComPact NS Circuit Breakers 630b to 3200 A Catalogue 2020 – PDF Manual

Description

Schneider Electric ComPact NS Circuit Breakers and Switch-Disconnectors – Catalogue 2020

The Schneider Electric ComPact NS range is the international reference in molded-case circuit breakers, and this 190-page catalogue brings together the full technical and commercial documentation for devices rated from 630b to 3200 A. Whether you are specifying a new switchboard, replacing a trip unit, planning a source-changeover scheme, or ordering accessories for an existing installation, this document gives you the original manufacturer data in one place. It covers fixed and withdrawable versions, manual and electrical operation, N/H/L/LB breaking capacities, and the complete Micrologic control unit family.

This is not a generic circuit-breaker overview. The document walks through the complete ComPact NS630b to 3200 range with the level of detail a panel builder, electrical engineer, or maintenance technician actually needs when working on a live project. You get the full breaking-capacity tables, the trip-unit selection logic, the insulation and safety clearance rules, the pole-pitch and bar-sizing data, and the wiring schematics for voltage releases, communicating modules, and source-changeover controllers.

The Micrologic section alone covers the 2.0, 5.0, 6.0 and 7.0 families along with the A (ammeter), E (energy) and P (power meter) measurement variants. Protection functions are broken down by threshold and delay: long-time, short-time, instantaneous, earth-fault and earth-leakage, with the front-panel adjustment dials and setting ranges described. The catalogue also documents the optional external sensors used for neutral protection, source ground return earth-fault protection, and residual earth-leakage protection, including CT ratings and compatible circuit-breaker sizes.

For anyone working on switchboards, the installation chapter gives the safety clearances for fixed and withdrawable devices, the minimum distances to panels, bars and adjacent protection devices, and the ambient-temperature derating tables for every connection type. Power dissipation and pole-resistance figures are included so you can calculate heat build-up inside an enclosure before you commit to a design. The dimensions and connection chapter provides front, rear and mixed connection drawings with drilling dimensions, spreader details, cable-lug adapter geometry, and vertical-connection adapter dimensions.

The communication and smart-panel content covers the Enerlin’X system, the IFE Ethernet interface, the IFM Modbus-SL interface, the I/O application module, and the FDM121 and FDM128 display units. Wiring diagrams show how the ULP cords and 24 V DC supplies are connected for fixed and withdrawable devices, and how the BCM ULP module fits behind the Micrologic trip unit. For projects involving generator sets, the motor-protection section details type 1 and type 2 coordination with contactors and the selection of trip units for motor feeders up to 750 kW.

Source-changeover systems are covered in their own section: manual systems with rotary-handle or keylock interlocking, remote-operated systems using the IVE unit, and automatic systems using the BA or UA controllers. The catalogue explains the mechanical interlocking options (connecting rods, cables, keylocks) and the electrical interlocking that prevents simultaneous closing of the normal and replacement sources. This is the kind of information that is hard to assemble from individual datasheets, and having it in one document saves significant engineering time.

Beyond the technical data, the catalogue includes the full order-form structure with catalogue numbers for circuit breakers, switch-disconnectors, trip units, chassis, connections, indication contacts, voltage releases, locking systems, rotary handles, motor mechanisms, communication modules, and test equipment. The spare-parts listings at the back give individual part numbers for replacement items, which makes it straightforward to identify exactly what is needed for a repair or retrofit without ordering a complete device.

Why This Manual Matters

Working on a ComPact NS circuit breaker without the manufacturer’s own selection and installation data means guessing at clearances, trip-unit compatibility, connection torque values, and communication wiring. This catalogue removes the guesswork. It tells you which Micrologic control unit fits which frame size, what the long-time rating plug options are, how the neutral protection is set on three-pole and four-pole devices, how the ZSI (zone selective interlocking) wiring is run, and what the cascading and current-limiting performance looks like at 400/440 V and 660/690 V.

For anyone maintaining or upgrading an existing installation, the electrical diagrams chapter is particularly valuable. It shows the terminal-block marking for indication contacts, the wiring for MX shunt releases and MN undervoltage releases, the carriage-switch connections for withdrawable devices, and the 24 V DC external power supply arrangement for the Micrologic trip unit. The diagrams are shown with circuits de-energised and devices in the normal position, which is the standard reference state for commissioning and troubleshooting.
