Description

The patented design of ABB's PI-Spring features the benefits of two technologies (Push-in and spring) in one connection.

Main benefits

50% faster connection time with push-in mode,
Reduced effort and conductor preparation time with spring mode,
Ease of wiring thanks to the front entry connection,
Perfect connections with or without ferrules proven by all certification testings,
Connection elasticity and design strictly controlled to ensure an easy and safe insertion of both conductor and screwdriver,
The flat surface of the PI-Spring makes wire and screwdriver insertion smoother and easier.

Main features

Connecting capacity from 0.2 to 25 mm² (26 to 4 AWG),
Stainless steel PI-Spring for high corrosion resistance (>1000 h),
The flat surface of the PI-Spring makes wire and screwdriver insertion smoother and easier,
Dimensions, coating and shape of the linking bar designed to get the lowest and most stable electrical contact value,
Very good electrical contact even in applications where vibration and shock are issues, such as railway.
