Products for all switching application from 25A to 3200A
• Applications with 2 interlocked switches Source transfer: manual or automatic switching (ATS) between two sources, either transformer or generating set (ﬁg. 1).
Earthing of equipment such as motors or electrical lines reserved for signalling, whilst isolating them from their power supply in a fail-safe way (ﬁg.2).
Inversion of loads: switching of the power supply from one load to another load in order to ensure that they both age at an equal rate (ﬁg. 3).
Inversion of phases on motors: inversion of the succession of phases supplying a motor in order to modify the direction of rotation (ﬁg. 4).
• Application with 3 interlocked switches UPS ‘BY-PASS’: isolation then bypassing of a secure UPS type power supply using 3 interlocked breaker switches assembled very close together (ﬁg. 5).
• Application with 4 interlocked switches Solution ‘ATS BY-PASS’: upstream and downstream disconnection of an ATS function (automatic switching) while guaranteeing the continuity of the distribution via a ’BY-PASS’ branch. Carried out using a single operating handle, this operation allows the ATS function to be separated for maintenance, in complete safety.
Linked to a switching function, the bypass branch means it is still possible to select the sources in the event of a failure of one of them (ﬁg. 6).
