About Fuses & Switches
Fuses and switches are essential components in electrical protection systems, designed to safeguard equipment, circuits, and personnel from overloads, short circuits, and fault conditions. By providing reliable isolation and fault protection, they help maintain the safety, performance, and continuity of electrical networks across a wide range of applications.
From low-voltage installations to critical medium-voltage power systems, the correct selection of fuses and switching devices is vital for protecting transformers, switchgear, motors, cables, and distribution equipment. These devices are engineered to operate quickly and reliably, minimising damage and reducing downtime during electrical faults.
LPINZ supplies a comprehensive range of general-purpose, medium-voltage, and specialised fuse solutions to suit utility, industrial, infrastructure, and renewable energy applications. Our products are sourced from trusted global manufacturers and designed to deliver dependable protection, compliance, and long-term performance in demanding electrical environments.
