The New ERICO® Power Block SB Series
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
Major diameter of the screw
Diameter of terminal hole= >95%
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.

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.
