IER’s 5kV and 15kV Load Interrupter Switchgear has been constructed with an integrated assembly of switches, bus, and fuses designed for meidum voltage circuit protection. Our medium voltage Switchgear provides reliable, safe switching and fault protection for circuits rated from 2.4kV to 15kV. IER’s Switchgear is ideal for applications where high-duty cycle operation is not required.
The quick-make, quick-break mechanism carries full-load current-interrupting capabilityies while current-limiting fuses provide accurate, premanently calibrated short-circuit detection and interrupting capacities. Blade position visibility greatly improves safety by assuring electric circuit de-energization.
