Abstract
A multi-phase vacuum contactor occupying a minimal space envelope. The contactor features a housing; a carriage; an electromagnetic actuator fixed to the housing and having a reciprocating armature connected to the carriage; and a plurality of vacuum interrupters each having a reciprocating stem for the actuation thereof, wherein the vacuum interrupters are fixed to the housing and circumferencially arranged about the electromagnetic actuating mechanism such that longitudinal axes of the vacuum interrupters are substantially parallel to a longitudinal axis of the electromagnetic actuating mechanism, and wherein the stem of each vacuum interrupter is connected to the carriage.
Claims7
A multi-phase vacuum contactor, comprising:
- a housing;
- a carriage;
- an actuating mechanism having a reciprocating actuating arm, wherein the actuating mechanism is fixedly mounted to the housing and the actuating arm is connected to the carriage;
- a plurality of vacuum interrupters, each having a reciprocating stem for the actuation thereof, wherein the interrupters are fixedly mounted to the housing and the stems are connected to the carriage such that the stroke of said actuating arm and the strokes of the stems are orientated in substantially parallel directions;
- and
- a resilient member disposed between the body of the actuating mechanism and the carriage for biasing the vacuum interrupters in the open position.
