  • Page 14: Description

    Product Description Description 1. Description The spring operating mechanism BLG 1002A is intended for operating a circuit- breaker with integrated opening springs. The opening springs are charged automatically by the mechanism on closing of the circuit-breaker, whereby the requisite energy for opening is obtained. Under no circumstances may the mechanism be operated with the spring battery charged, without first being fitted and trimmed with the associated circuit-breaker.

  • Page 15: Normal Operating Mode

    Description Product Description 1.1 Normal operating mode During normal service the circuit-breaker is in the closed position. The opening spring (14) on the circuit-breaker and the closing springs (7) in the operating mechanism are charged. The circuit-breaker is kept in the closed position by the operating mechanism’s opening catch gear (1).

  • Page 16: Opening Operation

    Product Description Description 1.2 Opening operation The latch in the opening catch gear (1) is released on opening of the circuit-breaker (1). The opening spring (14) pulls, via the pull-rod (13), the operating lever (4) to the left. The movement is damped by the opening dashpot (3) at the end position before the operating lever (4) rests against the cam disc (5).

  • Page 17: Closing Operation

    Description Product Description 1.3 Closing operation On closing of the circuit-breaker, the latch is released in the closing catch gear (2). The chain section (17) is released and transfers the closing spring’s (7) energy to the cam disc (5). The cam disc rotates 360° clockwise and pulls the operating lever (4) to the right until the opening catch gear (1) engages.
