# **Data Sheet | Item Number: 740-103** PCB terminal block; 2.5 mm²; Pin spacing 5 mm; 3-pole; CAGE CLAMP®; gray **https://www.wago.com/740-103** 

# Color: r gray Similar to illustration Dimensions in mm L = pole no. x pin spacing . PCB terminal block, 740 Series, gray 

Quick and easy connections are guaranteed with this PCB terminal block (item number 740-103). It offers the flexibility needed for different mounting types. Strip lengths must be between 6 and 7 mm when connecting conductors to this PCB terminal block. This product features one conductor terminal and utilizes CAGE 

# CLAMP®. Our CAGE CLAMP® connection provides a dependable and maintenance-free way to connect all types of conductors. You do not need to prepare the conductor in any way, such as crimping ferrules. The item's dimensions are (15 x 23.3 x 11.1) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is ideal for conductor cross sections ranging from 0.08 mm² to 2.5 mm². 

# The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. THT is used to assemble the PCB terminal block. Insert the conductor at an angle of 0°..
