Connections in mobile applications

Oct 24, 2012 | Cables and Accessories

To aid the reliable connection and disconnection of heavy duty power cables, Multi-Contact has introduced its new 21BV connector – a round, single-pole insulated connector that provides reliable operation for as many as 5,000 mating cycles.

Applications include connecting mobile generator sets, standby power units, switchgear, event cabling, test facilities and other uses where copper cables need to be joined together or plugged into panel mounted sockets.

The 21BV has a number of advantages over Multi-Contact’s comparable 30BV connector, being more compact, easier to assemble and with a higher current carrying capacity of 800A.

The 21mm diameter CAT III connector is well suited for external use, providing environmental protection to IP65 and IP68 when mated, with an extended temperature range of -40°C to 120°C. It is IP2X touch protected when unmated. Termination is by crimping or threaded lug.

The rated voltage is 1,000V and conductor cross-sections between 150mm2 and 400mm2 are accepted. Colour marking is provided on the insulation and six mechanical codings are available.

A bayonet locking system simplifies connection and the connectors can be assembled without special tools. A locking pin prevents accidental disconnection and the connector can only be unlocked using a separate tool. An optional panel mount adapter can dress the cable downwards to save space and minimise transverse forces. Strain relief is provided by cable glands available in two sizes.

A remote indication of when the connector is mated can be provided with the optional MS-S21 microswitch, which switches immediately before the locking device engages.
