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.

General Description

A fast operating multi contact attracted armature relay with a high degree of mechanical stability.

Type VAJH 13 relay has hand 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.

Type VAJHM 13 high burden relay with hand reset contact is recommended

where supervision of trip relay coil is desired.

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.

Coil rating

24, 30, 48, and 110 or 220 V DC as standard. 110 or 200 V AC for Vajh13, Vajh23 and VAJS 13. External resistor supplied with type VAJS13 relay for 110V and above.

Voltage Band For Satisfactory Operation

50 to 120% of rated voltage.

Operating Time

10 milliseconds nominal, at rated voltage. (12.5mSec for 24 & 30V models).
