General ■ YGLR Series fuse group of
isolation switch ( hereinafter short for switch) is multi-pole and manual operation switch, whose housing is made of glass fiber reinforced unsaturation polyester, it has merits of high dielectric property, guard capacity and reliable operation.
■ The operation mechanism, it is accelerate mechanism of spring energy s torage, in stantaneous release, it is also a mechanism that is instantaneous making and breaking multi-breakpoint contact. It is no related with the speed of operation handle, t hus, it e xtremely improves each electric performance and mechanical performance.
■ Fuse group of isolation switch can makes sure making and br eaking cir cuit with load, and it has r eliable over current or short-circuit breaking protection.
■ Obviously saw the breaking state.
■ With strong hot and humidity proofing.
■ Because the switch owns the merits of graceful appearance, novel, simple, small volume and complete function, it is best selection among the same products .
Model description 
Note: don't note if the function in the box is not necessary.
F-NC or NO auxiliary contact,
S-NO+ NC S type auxiliary contact,
U- U type auxiliary contact.
Example for lecto type : rated current 160A, 3 poles,
side face operation in the cabinet

YGLR-63~1250A / I Type Fuse Group of Isolation Switch It makes sure making and breaking circuit with load, with reliable over-current and short-circuit breaki ng prote ction, a lso obviously saw the breaking state.Own two poles, three poles, four poles ( three poles+ switch neutral pole). The fuser can be divided into 23 sp ecs from 63A to 1250A.
Structure and operation mode ■ Direct operation on front face: the handle is installed on the front face of switch.
■ Direct operation on side face: the handle is installed on the right of switch ( it is noted separately if the handle is installed on theleft of switch).
■ Front face operation outside of cabinet: the handle is installed on the front face outside of the distribution cabinet door.
■ Side face operation outside of cabinet: the handle is installed on the right of distribution cabinet outside. ( it is noted separately if the handle is installed on the left)
