Transfer switches and switchgear, stocked in New Zealand.
What do you need to switch?
Telergon covers the full range of low-voltage switching requirements. Start with your application and we'll point you to the right series.
Five series. Every switching requirement covered.
All series are stocked in New Zealand and available with full technical documentation, wiring diagrams, and PAC support.
For main isolation, service switching and feeder protection in switchboards and distribution panels — rated for on-load switching with high short-circuit withstand, 40 A to 6300 A. The most widely specified Telergon product and the default starting point for most isolation duties.
For high-current isolation where Icw performance is the critical spec — BESS, UPS, data centres and utility substations. Industry-leading fault ratings in a compact footprint, 1250 A to 3150 A. (Lower current? The S5 covers most boards.)
For manual I–0–II changeover on generator backup boards, bypass panels and critical load switching. Heavy-duty, with advanced switched neutral and motorisation-ready, 125 A to 3150 A. The widest changeover range.
For everyday generator-backup changeover on standard commercial distribution boards — a practical, cost-effective choice, 200 A to 1250 A, 8,000 cycles. (Heavier duty or switched neutral? Step up to the S5F.)
For automatic failover where power continuity can't rely on manual operation — hospitals, data centres and emergency services. Monitors both supplies and transfers automatically on failure, with LCD programming, RS485 and BMS integration, 63 A to 630 A.
