Why Choose the ABB E4.2/MTP 3200 MP 4p Earth DOWN?
The ABB E4.2/MTP 3200 MP 4p Earth DOWN, order code 1SDA081797R1, is an earthing switch with making capacity designed for the ABB SACE Emax 2 low-voltage air circuit breaker system. Based on the E4.2 frame size, this four-pole moving part provides a dedicated means of earthing the lower terminals of compatible withdrawable switchgear during maintenance and electrical isolation procedures.
As part of the ABB Emax 2 range, the E4.2/MTP is specifically designed for demanding low-voltage power distribution installations. Unlike a standard maintenance earthing device, the MTP configuration is an earthing switch with making capacity, providing a purpose-designed solution for compatible Emax 2 switchgear where controlled earthing functionality is required.
This version has a rated uninterrupted current Iu of 3200 A, features a four-pole configuration and provides the earth connection from the lower terminals. Its withdrawable moving-part format allows it to be used with the appropriate fixed part in compatible ABB Emax 2 E4.2 installations.

Reliable Earthing for Low-Voltage Switchgear
Earthing switches are used in electrical distribution systems to establish an intentional connection to earth during defined maintenance and isolation procedures. The ABB E4.2/MTP is an earthing switch with making capacity, engineered specifically for compatible withdrawable Emax 2 switchgear and high-current low-voltage distribution applications.
The moving-part design interfaces with the appropriate switchgear fixed part, while the Earth DOWN configuration connects the lower terminals to earth. The four-pole arrangement makes this model suitable for compatible E4.2 installations requiring earthing across four poles.
Typical Applications
- Low-voltage power distribution switchboards.
- ABB Emax 2 compatible withdrawable switchgear.
- Industrial electrical distribution systems.
- Electrical isolation and maintenance procedures.
- Manufacturing and process plant switchgear.
- Commercial and infrastructure power distribution systems.
