Havells Euro II FP 100A

The Havells Euro II FP 100A is a high-performance 4-Pole Switch Disconnector engineered for heavy-duty 3-phase and neutral isolation. Built with flame-retardant thermoplastic and rated for AC-23A utilization, this 100A main switch provides a robust manual break for industrial and commercial distribution boards, ensuring total safety during electrical maintenance without the footprint of a bulky MCCB.

Quick Answer

The Havells Euro II FP 100A is used as a primary isolation point in 415V 3-phase systems, capable of safely switching motor loads or high-inductive circuits up to 100 Amps on a standard DIN rail setup.

✓100A High-Capacity Four-Pole (FP) configuration for complete 3-Phase + Neutral isolation.
✓AC-23A Utilization Category: Optimized for switching motor loads and highly inductive circuits.
✓Flame-Retardant Thermoplastic Housing for superior thermal stability and dielectric strength.
✓IP40 Rated Protection: Safeguards against solid particles larger than 1mm in indoor environments.
✓Universal DIN Rail Compatibility: Designed for seamless integration into modern Euro-series distribution boards.

Choose the Havells Euro II FP 100A if you require a dependable, space-efficient isolation solution for a 100A 3-phase system. Its combination of AC-23A switching capability and Havells' manufacturing reliability makes it the top choice for commercial contractors and panel builders.

✓ Who Should Buy

  • •Electrical contractors installing main distribution boards for commercial buildings.
  • •Industrial facility managers needing a dedicated 3-phase + neutral isolation point for machinery.
  • •Panel builders looking for standardized DIN-rail mountable disconnectors with high thermal resistance.

✕ Who Should Avoid

  • •Users looking for automatic short-circuit or overload protection (this device requires an upstream MCB or fuse).
  • •Direct Current (DC) solar applications, as this unit is strictly rated for 415V AC.
Product Overview
The Havells Euro II FP 100A belongs to the prestigious Euro II series, a benchmark in Indian electrical switchgear since 2015. Unlike standard switches, this disconnector is designed to handle a continuous 100A load at 415V, making it the ideal 'Main Switch' for commercial panels. Its manual toggle mechanism provides a positive contact indication, ensuring that when the switch is OFF, the circuit is physically and reliably air-gapped. Crafted with high-grade thermoplastic, the unit resists tracking and heat deformation, which is critical for high-current applications. As a non-automatic switch, it focuses purely on the integrity of the connection and the safety of the isolation, making it a prerequisite for any multi-pole circuit that requires periodic downstream maintenance.

Engineering Analysis
From an engineering perspective, the Havells Euro II FP 100A excels in its mechanical endurance and contact pressure. The AC-23A rating implies that the internal silver-alloy contacts are reinforced to withstand the arcing associated with switching inductive loads (like large motors or transformers). The screw terminals are oversized to accommodate large cross-section cables (up to 50mm²), ensuring a gas-tight, low-resistance termination that prevents terminal burnout under full load.
