MERSEN FUSE Ind./switch door pos.1.002.643 1.002.643
Mersen T1022988 is a switch door position indicator with a 5 A, 250 V change-over microswitch contact designed for the MULTIBLOC 000.RST8 NH fuse switch disconnector system.
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.

Reliable Switch Position Indication
Position indication accessories allow the mechanical state of electrical switching equipment to be communicated to monitoring and control circuits. A microswitch changes contact state as the associated switch mechanism moves, enabling compatible control equipment to receive an electrical indication of the switch door position.
The Mersen T1022988 is specifically designed for the MULTIBLOC® 000.RST8 three-pole NH fuse switch disconnector. Its change-over contact provides flexible signalling options for compatible auxiliary circuits, making the accessory suitable for industrial switchboards and distribution systems where switch position feedback is required.
Typical Applications
- Mersen MULTIBLOC® 000.RST8 fuse switch disconnectors.
- Switch door position indication.
- Industrial low-voltage distribution panels.
- Electrical switchboards and switchgear assemblies.
- Auxiliary status signalling circuits.
- Industrial control and monitoring systems.
- Panel building and electrical distribution equipment.
