Wide range of cross-sections of aluminum or copper conductor connection possibilities – UL


Time saving and reliability>95% fill ratio

• Allows for conductor connection with or without ferrule.

• High fill ratio will help the set screw to provide a good

electrical connection between the cable and the copper

block, and reduce the chance that cable strands will

escape the connection.

• The connection contact surface is optimized and

providing excellent electrical contact and mechanical resistance.

Easy fixing – all models

•2 positions (open/close)

•Clips onto DIN rail or mounts to panel with screws

IP 20

• All models provided

standard with IP20 cover

• Finger Safe

Flat conductors direct connection

•SBFXX models can be connected with flat conductor

like ERICO® FLEXIBAR® or IBSB/IBSBR Power Braid

with screw compression system.

•No tools needed to punch or drill ERICO FLEXIBAR.

* Refer to UL File E198301 for conditions of acceptance.

ERICO Power Blocks have

been Tested and Certified

according to IEC 60947-7-1 &

UL 1059, and have very high

short circuit current

resistance.

Assembly manufacturer, Panel

builders, OEM’s, machine

builder needs to ensure that

the necessary contact

pressure corresponding to the

current rating and the short-

circuit strength of the

apparatus and the circuit is

maintained.
