03 / CONSTRUCTION
FRONT ACCESS.
ROOM FOR YOUR PROJECT.
Standard metal sections for wall or free-standing installation. Cable connections are made from the front through the dedicated cable-way.
MODULARITY
Space for every function.
Ten equipment modules per section and two auxiliary modules, one at the top and one at the bottom.
EXTENSION
Ready to expand on both sides.
Sections designed for extension to the left and right, for both main busbars and auxiliary circuits.
CONNECTIONS
Cables from above or below.
Incoming and outgoing cables can be arranged from the top and/or bottom. The base provides cable openings and fixing holes.
Frame and finish
Sendzimir-galvanised steel frame. Front and enclosure panels are degreased and finished with epoxy-polyester powder coating. Top lifting eyebolts assist handling.
Natural ventilation
A ventilation duct and openings in the front, internal partitions and roof provide natural heat dissipation.
Protective-circuit continuity
Self-bonding nuts and bolts earth the structure. A copper protective bar runs the full length of the switchboard and is sized for the prospective fault current.
Live parts can only be reached after removing metal barriers or insulating screens.

07 / TECHNICAL FAQ
PROJECT QUESTIONS.
PRECISE ANSWERS.
Answers to support selection and prepare your technical discussion with ICEL.
Let’s discuss your plant ↗LPB or LMCC: which switchboard is right for distribution and motors?
LPB is designed for low-voltage power distribution. LMCC is designed for centralised motor control. Both families share a modular structure, with compartments accommodating circuit-breakers or motor starters to suit the project.
Do you manufacture LPB switchboards for photovoltaic inverter paralleling?
Yes. ICEL builds LPB configurations for power collection and distribution in photovoltaic plants. Selection starts with the number and characteristics of the inverters, single-line diagram, protection and connections. Voltage, current, apparatus and dimensions must be checked against the project configuration and this catalogue.
What electrical ratings does the range offer?
Rated assembly current is up to 2,500 A, with Ue up to 690 V AC or 750 V DC. Rated short-time withstand current is up to 50 kA for 1 s, with peak withstand current up to 105 kA. Voltage ratings depend on the installed equipment and ratings apply to the project configuration.
Does LPB / LMCC use fixed or withdrawable units?
LPB / LMCC is ICEL’s fixed-unit switchboard family. The catalogue provides for fixed or removable apparatus: moulded-case circuit-breakers for LPB and motor-control equipment in individual compartments for LMCC. The device arrangement is distinct from the compartment structure.
Can I specify ABB, Siemens or Schneider components for LPB / LMCC?
Yes. ICEL can integrate these brands in its low-voltage range. Equipment selection for LPB / LMCC must suit the required functions, compartment dimensions and configuration characteristics. The catalogue’s dimensional tables are indicative; the combination is defined and checked during project engineering.
Can the switchboard be installed against a wall?
Yes. Access and cable connections are from the front; the catalogue allows installation against a wall or in the centre of a room. The installation drawing shows a front aisle greater than 1,000 mm and an example with two back-to-back rows. Actual clearances must be checked against the project drawings.
Which forms of internal separation are available?
The catalogue identifies form 2b for version M and form 4a for version S. Version S uses compartments separated by metal partitions. Separation, equipment and module dimensions are defined together during project engineering.
Which motor-starter arrangements are listed?
The 380 V table lists direct-on-line, reversing and star-delta starters, with fuses or a circuit-breaker. Listed motor powers range from 11 to 160 kW. C dimensions are indicative and refer to the combinations in that table; they must not be extended automatically to other voltages or equipment.
Can the switchboard be extended, and where do cables enter?
Sections are designed for extension on both sides, for both main busbars and auxiliary circuits. Incoming and outgoing cables can be arranged from the top and/or bottom. The cable-way is accessible from the front.
What information is needed to size LPB / LMCC and request a quotation?
Selection starts with the electrical diagram, currents, motors and selected devices. The catalogue provides indicative compartment dimensions and standard sections; usable height HC varies with busbar current. Final dimensions, thermal loading and connection space are checked during project engineering.
