Why Choose the ABB 1SDA074373R1 E2.2/MTP 2500 MP 4-Pole Earthing Switch?
The ABB 1SDA074373R1 is an E2.2/MTP 2500 MP 4-pole earthing switch with making capacity designed for the ABB SACE Emax 2 air circuit breaker platform. Part of the ABB Emax 2 derived-version range, this withdrawable device provides a dedicated earthing function for compatible low-voltage switchgear installations.
Based on the Emax 2 E2.2 frame size, the 1SDA074373R1 has a rated uninterrupted current of 2500 A and a 4-pole configuration. The MP moving-part construction is designed for use within a compatible withdrawable Emax 2 arrangement, providing a robust solution for earthing duties in industrial and commercial power distribution systems.
The Earth DOWN configuration identifies the version with the earth connection from the lower terminals. Unlike the Emax 2 MT earthing truck, the MTP version is an earthing switch with making capacity, providing the dedicated functionality required for appropriately engineered switchgear earthing applications.

Earthing with Making Capacity for Emax 2 Switchgear
Earthing switches are used in appropriately designed switchgear to connect relevant conductors to earth as part of electrical isolation and safety procedures. The ABB Emax 2 MTP derived version combines the withdrawable Emax 2 architecture with making capacity, distinguishing it from the MT earthing truck and providing a dedicated solution for applications requiring this functionality.
The ABB 1SDA074373R1 combines the E2.2 frame, 2500 A current rating, four-pole construction and lower-terminal earth connection in a withdrawable moving-part configuration. This makes it suitable for compatible Emax 2 installations requiring a purpose-designed MTP earthing device for demanding low-voltage switchgear applications.
Typical Applications
- ABB Emax 2 E2.2 withdrawable switchgear installations.
- Low-voltage main distribution switchboards.
- Industrial power distribution systems.
- Commercial and infrastructure electrical installations.
- Switchgear earthing and electrical isolation arrangements.
- Four-pole systems requiring earthing from the lower terminals.
