What’s the Earth loop impedance value Zs for the GV3 range of MPCB's?

Search FAQs

The charts below detail the Earth Loop impedance (Z_s) for the GV3 range of Motor Protection Circuit Breakers (MPCB) for any TN system based on the British Standard BS7671:2008+A3:2015

Two documents are also attached:
1) Sheet with Zs charts of Tesys motor protection circuit breakers:

Tesys GV2
Tesys GV3
Tesys GV4
Tesys GV7
Tesys U

2) Explaination of the calculation of the maximum Earth Loop Impedancee

This also includes additional information about:

Motor Rated devices
Ambient Temperature
