LBV Switch-Disconnectors
40A - 1600A, TP or TPSN

Each compact frame size, up to 1600A, is enclosed in a moulded,
insulated housing which provides protection against the ingress of dust and foreign bodies. This housing also supports the fixed contact assembly ensuring that each contact is isolated from the operating mechanism when in the ‘OFF’ position. Visual indication of contact separation is provided.

Efficient operation and extended contact life results from the switch operating mechanism and the clip and blade wiping action, fixed and moving contact design.

The fixed contacts form part of the incoming and outgoing terminals which are of the box clamp type up to 63A and tinned copper lugs from 125 to 1600A ratings.

The moving contact assembly rigidly supports each pair of moving contacts and ensures simultaneous action of each contact pair during switching operations. Each moving contact pair consists of two silver plated copper contacts, spring assisted to ensure efficient contact.This spring assistance also compensates for repulsion stresses developed under normal operating conditions or when the switch is subject to high electro-dynamic forces. Each pole houses separate arc shutes to ensure arc extinguishment during operation.

Manually independent operating mechanisms are of the “stored energy” type. Operation of the handle loads the mechanism up to a point that the stored energy in the spring system is sufficient to change the position of the moving contact train ensuring quick make and break operation.

Handles and 'ON-OFF' Position Indication
Black moulded handles (IP54) and operating shafts are supplied with each switch for door mounting. Handles may be padlocked in the ‘OFF’ position and incorporate a door interlocking facility which may be defeated by a competent, authorised operator.

‘ON-OFF’ position indication is threefold being shown on the operating handle base, the switch housing and, via a window in the switch housing, on the moving contact assembly.

Applications
The LBV range of switches is suitable for AC operation up to 690V single phase or three phase.

DC operation up to 250V (= 15ms max) may be achieved by series connection of three pole devices as shown in table 6.

Switch Ratings
The load break switch range has been tested to the following specifactions:
BS EN 60947–3 & IEC 60947–3.
