Voltage Operated Auxiliary Relay Voltage Operated Auxiliary Relay with SR Contracts
Features :
Contacts conforms to IS : 3231. Duty : 1250VA. Attracted armature type compact design with positive action. Din Standard size compact cabinet. SR contacts are available (with or without flags). Two independent coils in one cabinet. Application :
High speed tripping duties. Low burden sensitive relay. To multiply the contacts, for Protection Relay.
Operation :
There are two independent relay elements in same cabinet. The coil of each element is directly brought on
terminals 9, 10 (element A) & 29, 30 (element B). After applying the energizing voltage at these terminals, the relay
operates and NO contact closes and NC contact opens. The Contacts are available as Self Reset (SR) type only.
Relays are available with or without flags and AC or DC coil.
