Hyundai HGM MCCB 3P 16–100 A 20 kA | Molded Case Circuit Breaker

The Hyundai HGM is a 3-pole 16–100 A molded case circuit breaker with 20 kA breaking capacity and a fixed thermal-magnetic trip unit. It protects main incomers, feeders, motors and distribution boards against overload and short circuit in residential towers, commercial buildings and factories. Several current ratings are available under this listing.

Key features

• Fixed thermal-magnetic protection with factory-set thresholds
• Breaking capacity 20 kA suitable for main and sub-main boards
• Rotary or toggle operation with clear ON/OFF/TRIP indication
• Wide range of accessories: shunt trip, undervoltage release, auxiliary contacts, rotary handles and motor operators
• Front-connected terminals for cables or busbars

Selection and installation tips

Select the MCCB rated current from the design load and cable ampacity, check that the breaking capacity (Icu) exceeds the prospective short-circuit current at the installation point, and choose an adjustable or electronic trip unit when selectivity with downstream breakers is required.

Frequently asked questions

What is the difference between an MCCB and an MCB?

MCCBs cover higher currents (typically 16–1600 A), higher breaking capacities and often adjustable protection, while MCBs are modular devices up to about 125 A for final circuits.

What does Icu mean?

Icu is the ultimate short-circuit breaking capacity – the highest fault current the breaker can safely interrupt.
