The series SGL load isolation switch applies at the distribution equipment of rate voltage up to AC 660V or DC 440V and conventional heat current up to 3200A and SOHz to make or break unfrequently the circuit or perform the electric isolation, wide used atthe fields, e.g. building,electric power, petrochemistry, etc.

The SGLC side operation load isolation switch is such one to add a side operating mechanism to the SGL load isolation switch, appliedfor side.

The SGLC side operation load isolation switch is such one to add a side operating mechanism to the SGLing the electric isolation by theside operation.

The SGLZ load-switchover isolation switch, consisting of two SGL load isolation switches that are of vertical or horizontal connection, applies for the switchover of the dual power supplies or the conversion of two load devices and secure isolation.

The switch meets the standard IEC60947-Sand GB14048.

The switch features pleasant appearance, novel and compact structure, smalldimension and completefunction, leading thecounterpart.

The switch adopts the module design, proper for making or breaking the circuit or performing the electric isolation. The switch of 1000A and above is only for electric isolation.

The switch adopts such a quick making mechanism that accumulates the energy by the spring and releases instantaneously and such acontact structure that simultaneously makes or breaks the double contacts that are of parallel connection, greatly improving the electrical and mechanical performance of the product.

The BMC and hand operating handle for the switch could provide very high dielectric performance, protection capacity and reliable operating security.

The switch has three poles odour poles (three poles+neutral pole with allowable making or breaking).

The switch front is fitted with the mark window to learn the making&breaking state of the contact, and it is possible to provide the rear window to direct observe the making& breaking state of the contact to assure the switch operation interms of reliability and security.

The handle could direct be fitted at the switch for operation (for short inside-cabinet operation), alternatively, itis possible to perform the operation outside the distribution cabinet via lengthened shaft (for short outside-cabinet operation), which would make the operation more convenient. It is possible to provide normally-open &-close auxiliary contact and install the special base plate and use the panel-front&-rear wiring mode to meet the various demand of the client.

In case of being at the breaking position "0", it is available to use two to three locks to lock the handle to prevent the misoperation.
