Fuse Load Break Switch FLBS

Introduction

ETI product serie

Our FLBS product line offers a range of core models and complementary accessories to meet diverse application requirements.

FBLS is manually operated 3 pole fuse combination switch in range 125 to 630A. It makes and breaks on load and provides safety isolation and protection against overcurrent for any low voltage electrical circuit. FLBS have been designed, qualified and tested according to the criteria defined by standards: IEC(EN) 60947-3, IEC 60269-1, IEC 60269-2. 

Application

ETI’s FLBS fuse load-break switch unites an NH fuse link with a three-pole load breaker, so a single module both isolates and protects.

• Motor circuits: Rated for AC-23 duties up to 630 A, the FLBS can make or break motors under load, and its NH fuse cartridges limit prospective faults to 100 kA rms, giving reliable short-circuit and overload protection.
• Protection of Industrial cabinets: Designed for panel or bus-bar mounting, it offers double-break isolation per pole, IP2X finger safety, and a dedicated TEST position that keeps control wiring live while the main conductors are open—perfect for maintenance without shutting down the whole board.
