New bat­tery mas­ter switches from Narva

Motor Equipment News - - NEWS -

From time to time, power iso­la­tion may be needed in some ve­hi­cles and equip­ment for main­te­nance and re­pair pur­poses, or even in an emer­gency sit­u­a­tion.

Rather than man­u­ally hav­ing to dis­con­nect bat­tery ter­mi­nals, a much faster and ef­fi­cient way of iso­lat­ing power is by fit­ting a bat­tery mas­ter switch.

Narva has a wide se­lec­tion of bat­tery mas­ter switches avail­able, with the range of switches hav­ing re­cently grown with the ad­di­tion of four new vari­ants suit­able for both 12 and 24V ap­pli­ca­tions.

New to the range is a ro­tary bat­tery mas­ter switch with re­mov­able keyed knob. Com­pact in size with a di­am­e­ter of just 45mm at its widest, this switch only re­quires a 29mm di­am­e­ter open­ing for fit­ting and also fea­tures an easy-turn knob. The keyed knob is also avail­able in the al­ter­na­tive in­sert colour in white.

Its com­pact di­men­sions make this switch ideal for pas­sen­ger cars, light trucks and sta­tion­ary en­gines and it can han­dle cur­rent loads of 1000A at 12V for five sec­onds, 500A at 24V for five sec­onds, 100A at 12V con­tin­u­ous load max­i­mum and 50A at 24V con­tin­u­ous load max­i­mum.

The sec­ond ad­di­tion to the line-up is a heavy duty dual pole bat­tery mas­ter switch with re­mov­able metal key – this one fea­tures dual cir­cuits for ve­hi­cles run­ning sin­gle or dual bat­ter­ies.

This unit can han­dle loads of 2,500A at 12V for five sec­onds, 1,250A at 24V for five sec­onds, 250A at 12V con­tin­u­ous load max­i­mum and 125A at 24V con­tin­u­ous load max­i­mum.

If ad­di­tional se­cu­rity is needed at the switch, a new Mas­ter Switch Lever type with Lock-out vari­ant has also been in­tro­duced. It fea­tures a fixed lever with in­te­grated lock­ing fa­cil­ity that can be se­cured with a pad­lock (not in­cluded) and has an IP66 rat­ing.

This switch comes with red bat­tery and yel­low starter on/off de­cal discs to suit the ap­pli­ca­tion, along with three rub­ber boot colours (black, red and yel­low) for eas­ier iden­ti­fi­ca­tion.

The last of the new ad­di­tions is a Dual Pole vari­ant of the Lever type with Lock-out switch. It fea­tures all the same great ben­e­fits but with the dual pole func­tion­al­ity for equip­ment with more than one bat­tery.

Both of the Lock-out switches are ready for loads of 2500A at 12V for five sec­onds, 1250A at 24V for five sec­onds, 250A at 12V con­tin­u­ous load max­i­mum and 125A at 24V con­tin­u­ous load max­i­mum.

The lat­est ad­di­tions sees Narva’s range of bat­tery mas­ter switches now num­ber 15 vari­ants – they’re avail­able from lead­ing au­to­mo­tive, trans­port, four wheel drive and marine out­lets na­tion­wide.
