Why Choose the ABB OMZC004 Bridging Bar Set?
The ABB OMZC004 is a purpose-designed four-piece bridging bar set for compatible four-pole ABB OTM40 motorised change-over switches. Identified by ABB order code 1SCA121325R1001, the set provides a manufacturer-matched solution for creating parallel connections between the upper or lower terminals of compatible OTM40 switching assemblies.
The OMZC004 uses finger-protected connection bars designed specifically for the four-pole OTM40F4C_ platform. The bars accommodate additional cable connections with conductor capacities of 2.5–25 mm² for a single conductor or 2 × 2.5–16 mm² for two conductors, providing flexibility when integrating the change-over switch into a distribution or automatic transfer system.
Supplied as the required four bridging bars for a four-pole OTM40 installation, the OMZC004 provides a coordinated ABB connection solution for switchboards, transfer-switch panels and OEM power-control assemblies.
