Why Choose the Mersen T1022988 MULTIBLOC Switch Door Position Indicator?

The Mersen T1022988 is a dedicated switch door position indicator designed for the Mersen MULTIBLOC® 000.RST8 NH fuse switch disconnector system. Also identified by Mersen catalogue number 1.002.643, this accessory uses microswitches to provide electrical indication of the operating position of the switch door.

The T1022988 incorporates a microswitch with one change-over contact rated at 5 A, 250 V. This allows the mechanical position of the compatible MULTIBLOC® switch door to be communicated to an external indication, monitoring or control circuit, providing useful status feedback within industrial electrical installations.

Designed specifically for the MULTIBLOC® 000.RST8, a size 000, three-pole NH fuse switch disconnector for busbar installation, the T1022988 is supplied as a set of three pieces. The accessory has a listed weight of approximately 0.1 kg and provides a manufacturer-designed solution for adding switch position indication to compatible Mersen equipment.
