Havells DHMGIFPX100

The Havells DHMGIFPX100 is a high-capacity 100A four-pole switch disconnector from the prestigious DHMGI series, specifically engineered for robust circuit isolation in three-phase systems. Unlike standard breakers, this model focuses on providing a secure, manual physical break in the electrical supply for maintenance and safety protocols. Built with high-grade thermoplastic and rated for AC-23A utilization, it excels in handling the demanding switching requirements of inductive loads in commercial and industrial electrical panels.

Quick Answer

The DHMGIFPX100 is a 100A, 4-pole (3-Phase + Neutral) main switch disconnector used for manual circuit isolation in 415V systems. It is best suited for panel boards requiring a reliable primary disconnect point without integrated overcurrent protection.

✓100A High-Current Rated Capacity
✓4-Pole Configuration (Full 3-Phase + Neutral Isolation)
✓AC-23A Utilization Category for Inductive Loads
✓Durable IP40 Rated Thermoplastic Housing
✓Universal DIN Rail Mounting Compatibility

Choose the Havells DHMGIFPX100 if you need a high-quality, branded 100A main isolator for a 3-phase system where upstream or downstream protection (MCBs/MCCBs) is already present. It is the gold standard for pure manual isolation.

✓ Who Should Buy

  • •Industrial panel builders needing a 100A 4-pole primary disconnect.
  • •Facility managers of commercial buildings with heavy 3-phase machinery.
  • •Electrical contractors looking for a reliable, brand-backed isolator for heavy-duty motor circuits.

✕ Who Should Avoid

  • •Residential users looking for a switch that automatically trips during a short circuit.
  • •Single-phase domestic installations (this is a 4-pole 3-phase industrial unit).
Product Overview
Launched as part of Havells' legacy DHMGI series, the DHMGIFPX100 remains a cornerstone for electrical distribution boards. It is designed to act as a master isolation switch, allowing operators to safely cut power to a 3-phase plus neutral circuit simultaneously. The manual toggle mechanism is engineered for high mechanical endurance, ensuring that even under constant use in industrial environments, the switch provides a definitive tactile response and secure connection. The unit is housed in a fire-retardant thermoplastic material that offers an IP40 degree of protection, making it resistant to solid objects larger than 1mm. Its compact architecture allows for easy integration into standard DIN rail setups, while the heavy-duty screw terminals are designed to accommodate large cross-section cables necessary for 100A current throughput, minimizing contact resistance and heat generation.

Engineering Analysis
The technical architecture of the DHMGIFPX100 prioritizes physical separation over electronic sensing. Because it lacks internal overload or short-circuit trip mechanisms, it functions with zero 'nuisance tripping,' making it a reliable point of entry for main power. The four-pole design is critical for modern 'Floating Neutral' prevention; by disconnecting the neutral alongside the phases, it eliminates the risk of potential differences across the neutral line during maintenance. The terminal geometry is optimized for high torque, ensuring that 100A of continuous current does not cause thermal degradation of the screw terminals over time.
