Hager HHA100Z 3-Pole 100A MCCB

The Hager HHA100Z is a 3-pole, 100A moulded case circuit breaker (MCCB) with a fixed thermal-magnetic trip unit, built for sub-main feeder and incoming circuit protection in UAE commercial and industrial distribution boards. It handles higher fault currents than a standard MCB, making it the right choice for main and sub-main protection on three-phase supplies.

Key Features

  • 3-pole, 100A rated current for three-phase incoming/feeder protection
  • Fixed thermal-magnetic (TM F/F) trip unit, fixed front DIN-rail mounting
  • Breaking capacity: Icu 25kA @ 400V AC / 35kA @ 240V AC (IEC 60947-2)
  • Service breaking capacity: Ics 25kA @ 230V AC / 20kA @ 400V AC
  • Rated operational voltage (Ue): 220–415V AC, 50–60Hz
  • IP4X protection, compact frame (130 × 75 × 68mm)
  • Rated for 20,000 mechanical and 10,000 electrical operations
  • Genuine Hager, Made in France, compliant with IEC 60947-2

FAQ

  • What's the difference between an MCB and an MCCB?
    An MCB (miniature circuit breaker) is typically rated up to 100A with a fixed, non-adjustable trip and lower breaking capacity, used for final circuits. An MCCB (moulded case circuit breaker) like the HHA100Z is built for higher currents and fault levels — up to 25kA breaking capacity here — and is used for main incomers, sub-mains, and feeder protection where an MCB's rating or breaking capacity would be insufficient.
  • When do I need an MCCB instead of an MCB?
    Use an MCCB where the prospective fault current or load current exceeds what an MCB is rated to handle safely — typically at the main incomer or major sub-main level of a commercial or industrial distribution board, rather than on individual final circuits.
  • How many poles do I need?
    The HHA100Z is a 3-pole device for three-phase circuits without a switched neutral, suited to three-phase feeders and main incomers on a 3-wire supply.
  • Can I install this myself?
    No. MCCBs are installed in distribution boards and panels by a licensed electrician, in line with UAE wiring regulations.
