(http://phoenixcontact.com/download) 

PCB terminal block, Nominal current: 20 A, Nom. voltage: 400 V, Pitch: 5.08 mm, Number of positions: 3, Connection method: Screw connection with tension sleeve, Mounting: Wave soldering, Conductor/PCB connection direction: 50 °, Color: green 

## Why buy this product 

- Screwdriver axis vertical to the PCB 

- Well-known connection principle allows worldwide use 

- Low temperature rise, thanks to maximum contact force 

- Allows connection of two conductors 

Angled connection enables multi-row arrangement on the PCB 

Integrated protective guide prevents incorrect insertion of the conductor underneath the tension sleeve w The latching on the side enables various numbers of positions to be combined
