Main Distribution Boards (MDB)

TECO GROUP designs and manufactures main distribution boards (MDB) that serve as the primary power intake and distribution point for commercial buildings, hospitals, factories, hotels, and infrastructure facilities. Every MDB is engineered, assembled, and factory tested in our own production facility — delivering type tested assemblies to IEC 61439-2 with ratings up to 6300A and short-circuit withstand up to 100kA, suitable for the most demanding electrical installations.

Our main distribution board capabilities include:

• Type tested assemblies to IEC 61439-2 and IEC 60439-1, with internal arc compliance to IEC/TR 61641.
• Rated current up to 6300A and rated operational voltage up to 690V AC.
• Short-time withstand current up to 100kA for high fault-level installations.
• Forms of separation from Form 1 through to Form 4b — tailored to project requirements for safety and maintainability.
• Robust, modular, and compact construction with front access, suitable for wall mounting.
• Ingress protection up to IP 54 to IEC 529.
• Integration with bus couplers (BC) for redundant supply configurations and source changeover.
• Custom panel widths (400–1200 mm), depths (600–800 mm), and heights (2000–2200 mm) to suit any electrical room layout.
