What type of component is this?
This is a PE through-type terminal intended for front mounting as an accessory for 3LD3 load disconnectors and switch disconnectors.
What is a PE through-type terminal used for?
A PE through-type terminal provides a protective earth connection point within a compatible switch disconnector assembly, helping route the protective conductor through the installation.
Which switch disconnector range is it designed for?
It is designed as an accessory for the Siemens SENTRON 3LD3 range of load disconnectors and switch disconnectors.
Is this component front mounted?
Yes. The product data identifies it as a front installation accessory, meaning it is intended to be mounted from the front of the compatible 3LD3 device or assembly.
What conductor sizes can it accept?
The terminal accepts coded conductor sizes from AWG 14 to AWG 6. In metric terms, the product data lists solid or stranded conductors at 1 x 2.5 to 16 mm², and finely stranded conductors with core end processing at 1 x 2.5 to 15 mm².
What tightening torque is recommended for the terminal connection?
The recommended tightening torque for the terminal connection is 3 N·m.
Is it part of the SENTRON range?
Yes. The product data lists the brand family as SENTRON, which is Siemens’ range covering low-voltage switching and protection devices.
Is this an auxiliary contact?
No. This item is a PE through-type terminal. Auxiliary contacts are separate accessories within the 3LD3 accessory range.
Is this the same as an N terminal?
No. This is a PE terminal for protective earth conductors. N terminals are neutral terminals and are listed separately in the 3LD3 accessory range.
What should be checked before fitting it?
Before fitting, check that the main device is from the compatible 3LD3 switch disconnector range, that the conductor size is within the permitted range, and that the terminal is tightened to the specified 3 N·m torque.
