Why Choose the ABB E2.2/MT 2000 MP 4p Earth DOWN?
The ABB E2.2/MT 2000 MP 4p Earth DOWN, order code 1SDA081787R1, is a dedicated Emax 2 earthing truck designed for compatible E2.2 withdrawable switchgear installations. Rated for 2000 A and configured with four poles, it provides an engineered means of connecting the lower side of the associated power circuit to earth during defined switchgear procedures.
The MT configuration is part of ABB's Emax 2 derived-device range and is intended for applications where controlled earthing of the power circuit is required during maintenance, isolation and servicing. This specific version provides its earth connection on the lower side, distinguishing it from corresponding E2.2/MT Earth UP configurations.
With its E2.2 frame size, 2000 A rated uninterrupted current, four-pole construction and withdrawable execution, the 1SDA081787R1 is designed to interface with the compatible fixed part of an Emax 2 installation. Its dedicated construction makes it suitable for switchboards requiring a purpose-designed ABB device for controlled circuit earthing.

Controlled Earthing for Emax 2 Switchgear
An earthing truck provides a dedicated means of intentionally connecting part of a compatible withdrawable switchgear power circuit to earth during defined isolation and maintenance procedures. Unlike a conventional Emax 2 circuit breaker used for normal switching and protection, the MT derived version is specifically configured to perform an earthing function within the compatible switchgear system.
The ABB 1SDA081787R1 provides an Earth DOWN arrangement for compatible four-pole E2.2 installations. Its 2000 A rating, withdrawable construction and dedicated Emax 2 mechanical interface make it suitable for industrial and infrastructure switchboards where controlled lower-side earthing is required.
Typical Applications
- ABB SACE Emax 2 E2.2 withdrawable switchgear.
- Lower-side power-circuit earthing.
- Four-pole low-voltage distribution systems.
- Switchgear maintenance and isolation procedures.
- Industrial and infrastructure power distribution switchboards.
- Compatible 2000 A Emax 2 installations requiring a dedicated earthing truck.
