1. What does TP+N mean on this isolator switch?
TP+N stands for Three Pole + Neutral, meaning the switch simultaneously disconnects all three phases (L1, L2, L3) and the neutral conductor, providing complete isolation for three-phase systems.
2. What are the typical applications for a 32A 4-pole isolator?
Ideal for isolating three-phase machinery, small distribution boards, sub-mains feeders, HVAC units, pumps, compressors, and commercial equipment requiring complete disconnection for safe maintenance.
3. Why choose a metal isolator switch over plastic?
Metal enclosures offer superior durability, impact resistance, and compliance with fire safety regulations (Amendment 3), making them ideal for commercial and industrial environments where robust construction is essential.
4. What cable size should I use with this 32A isolator?
With 16mm² terminal capacity, suitable cable sizes include 4mm², 6mm², or 10mm² depending on run length and installation method. For 32A, 6mm² is typically recommended for standard installations.
5. Can this switch be used as an emergency stop device?
Yes, as a 4-pole isolator, it can function as an emergency switching device for three-phase equipment, providing rapid disconnection of all live conductors in emergency situations.
