High Speed Tripping Relays VAJS13 With (4NO+0NC)

Features
• High speed operation
• High degree of mechanical stability
• Positive action without chatter
• Compact

Application
High speed tripping duties where a number of simultaneous switching operations are required.

Protective relays are precise measuring devices, the contacts of which should not be expected to switch large electrical loads. In some cases, the protective relay may trip a circuit breaker directly, or according to the coil rating and the
number of circuits to be energized, may do so using a VAJ tripping relay. The VAJ relay interfaces the protection to provide the higher contact capacity, additional contacts for tripping multiple circuit breakers, control functions, signalling and
interlocking.A fast operating multi contact attracted armature relay with a high degree of mechanical stability. Type VAJS 13 relay has self reset contacts and is available in two versions high burden and low burden. Type VAJS 13 has self reset contacts and is a low burden relay.The operating current for all versions is in excess of 0.025 amp.and the relays are suitable for operation on D.C supplies fitted with a negative potential biasing device. High burden relays are recommended in high security circuit breaker tripping circuits. The high burden provides immunity against operation due to capacitance discharge currents. Low burden relays are generally used when a number of simultaneous operations are to be initiated by a single protective relay having insufficient contacts of its own and where series connected operation indicators are not used.
