Features

All certification testing performed Connection elasticity and design
with non prepared wires, ensuring strictly controlled to ensure an easy
perfect connections with and safe insertion of both conductor
or without ferrules and screwdriver

The PI-Spring technology has successfully
passed aging tests (30 days temperature rise
test and 14 days heat cycling test)
guaranteeing the perfect long-term contact
quality of our screwless technology
Flat surface of the PI-Spring
makes wire and screwdriver
insertion smoother and easier
Excellent pulling strength
exceeding IEC standard
requirements

Dimensions, coating and shape Stainless steel PI-Spring for
