Introduction of VAA11 Alstom Auxiliary Relay
VAA11 relays are voltage worked relays. The relays are drawn in armature units of minimized plan with positive action and a high degree of mechanical stability. The relays can be supplied with self, or hand reset contacts and changeover contacts. Standard contacts are of copper/silver alloy. They are shaped and positioned to guarantee a solid and low opposition normally open or regularly shut contact. Standard VAA 11/21 relays are appropriate for ac/dc supply and standard VAA11 relays are suitable for dc supply only. Assistant relays with delay on getting or drop off can be provided on explicit solicitation. Essentially relays with attractive victory contacts can likewise be provided on explicit solicitation.
Features Of VAA11 Alstom Auxiliary Relay
VAA11 relays are Simple and robust construction
VAA11 relay have high mechanical stability
VAA11 relays are Heavy duty
In VAA11 relays reset is available in ac/dc version
Application Of VAA11 Alstom Auxiliary Relay
VAA11 relays are applicable in Control, alarm, indication and other auxiliary duties in ac or dc systems
Alstom Auxiliary Relay can withstand 5 million operations without servicing
VAA Plug-in-relays is specially designed for industrial control duties requiring respective switching operations.
VAA relays can withstand an operation of up to 600 per hour.
Conclusion
The capacity of Auxiliary Relays isn’t simply restricted to the stagger of the harmed circuit. For instance, in the event of stumbling happens, there is still some legitimate setting, yet at times when the issue is extreme, in that circumstance just reset-start the framework can make it serious, so here we really want total lockdown. Presently again by consistent when the hand-off contact is shut which is exceptionally light for quicker reaction it doesn’t have the option to disengage the vigorously stacked excursion circuit.
