Why Choose the ABB E2.2/MT 2000 MP 3p Earth DOWN?
The ABB E2.2/MT 2000 MP 3p Earth DOWN, order code 1SDA081786R1, is a dedicated Emax 2 earthing truck designed for compatible E2.2 withdrawable switchgear installations. Rated for 2000 A and configured with three poles, it provides an engineered means of connecting the lower power terminals of the associated switchgear circuit to earth.
The MT earthing-truck configuration is derived from ABB's Emax 2 platform and is intended for use in switchgear where safe and controlled earthing of the power circuit is required during maintenance and operational procedures. This version provides its earth connection from the lower terminals, distinguishing it from the corresponding upper-terminal E2.2/MT configuration.
With its E2.2 frame size, 2000 A rated uninterrupted current and three-pole arrangement, the 1SDA081786R1 is designed for withdrawable Emax 2 systems. Its dedicated mechanical configuration allows it to interface with the compatible fixed part in place of the normal withdrawable circuit breaker when the specified earthing procedure is required.

Controlled Earthing for Emax 2 Switchgear
An earthing truck is used in compatible withdrawable switchgear to establish an intentional earth connection on the power circuit during defined maintenance and safety procedures. Unlike a standard Emax 2 circuit breaker, the MT derived version is specifically configured for earthing rather than normal circuit protection and switching duties.
The ABB 1SDA081786R1 provides the earth connection through the lower terminals of a compatible E2.2 installation. Its 2000 A, three-pole configuration makes it a dedicated accessory for Emax 2 systems requiring controlled earthing of the lower side of the switchgear circuit.
Typical Applications
- ABB Emax 2 E2.2 withdrawable switchgear.
- Lower-terminal power-circuit earthing.
- Industrial low-voltage distribution switchboards.
- Switchgear maintenance and isolation procedures.
- Commercial and infrastructure power distribution systems.
- Compatible three-pole 2000 A Emax 2 installations.
