The ‘SLB’ switch disconnectors have been designed according to standard EN-IEC 60947-3 for its use in low voltage civil and industrial installations. Moulded case design with frame parts of non - flammable glass fibre reinforced polyester with high mechanical and electrical track resistance and with low water absorption. Excellent thermal and dielectric properties of insulating materials adjacent to current carrying parts: Dielectric strength, electrical track resistance and dimensional stability at high temperatures.

‘ON-OFF’ POSITION INDICATION ‘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.

TERMINAL SHROUDS A SLB switch can be completed with finger safe terminal shrouds. They can be mounted on either the incomming, outgoing or all terminals.

Changes, errors and misprints reserved.
