Why Choose the Mersen M1023442 MZHD Switch-Door Position Indicator Set?
The Mersen M1023442 is a set of three MZHD switch-door position indicators designed for use with compatible Mersen MULTIVERT® NH vertical fuse-switch disconnectors. These compact signalling accessories detect the position of each switch operating cover, allowing the open or closed status of the fuse-switch poles to be communicated to an external monitoring or control circuit.
Designed for MULTIVERT® 160 A size 00 fuse-switch disconnectors with three individually switched poles, the M1023442 includes one position indicator for each pole. The set is intended for MULTIVERT installations mounted on standard 185 mm busbar systems, providing a manufacturer-matched solution for switch-position monitoring.
Each indicator provides one normally open contact and one normally closed contact, rated at up to 5 A at 250 V. This changeover signalling arrangement supports integration with indicator lamps, relays, programmable logic controllers and building or industrial monitoring systems.
Key Advantages
- Provides reliable switch-door position monitoring.
- Supplied as a set of three indicators for three individually switched poles.
- Designed specifically for compatible Mersen MULTIVERT® equipment.
- Each indicator includes one normally open and one normally closed contact.
- 5 A, 250 V contact rating supports common signalling circuits.
- Suitable for connection to PLCs, relays, alarms and status indicators.
- Compact construction simplifies installation within switchboard assemblies.
- Helps improve equipment-status visibility and maintenance safety.

- Three indicators supplied.
- Designed for MULTIVERT® 160 A size 00 fuse-switch disconnectors.
- Suitable for three individually switched poles.
- Compatible with MULTIVERT equipment for 185 mm busbar systems.
- One normally open contact per indicator.
- One normally closed contact per indicator.
- 5 A maximum contact rating.
- 250 V maximum switching voltage.
- Designed for electrical status indication and interlocking applications.
Reliable Switch-Position Monitoring
The Mersen M1023442 allows the operating-cover position of a compatible MULTIVERT fuse-switch disconnector to be incorporated into an electrical monitoring system. When a switch cover changes position, the corresponding indicator contact changes state, providing a clear electrical signal that can be used for local indication, remote monitoring or control-system logic.
Because each indicator includes normally open and normally closed contacts, the set can support a variety of circuit arrangements. Typical functions include confirming that fuse-switch covers are closed, generating an alarm when a pole is opened or preventing associated equipment from operating until the required switch position has been confirmed.
Typical Applications
- Industrial low-voltage switchboards.
- MULTIVERT fuse-switch disconnector assemblies.
- Remote switch-position monitoring.
- PLC and automation-system inputs.
- Electrical safety interlocking circuits.
- Alarm and status-indication systems.
- Cable distribution cabinets and feeder pillars.
- OEM switchboard and panel manufacturing.
