Why Choose the Cembre 2280155 A24B-M10/19 Narrow-Palm Copper Crimp Lug?
The Cembre 2280155, also identified as A24B-M10/19, is a professional narrow-palm copper crimp lug designed for terminating 120 mm² copper conductors onto M10 connection points. Its contained 19 mm palm width makes it particularly suitable for low-voltage circuit breakers and other electrical equipment where conventional terminal palms may be too wide for the available connection space.
Part of Cembre's contained-palm terminal range, the A24B-M10/19 is manufactured from Cu-OF CW008A electrolytic copper tube conforming to UNI EN 13600. The terminal is annealed to provide optimum ductility during crimping and electrolytically tin-plated to help prevent oxidation, providing an effective combination of electrical conductivity, mechanical strength and installation durability.
Designed for 120 mm² class 2 stranded copper conductors, the Cembre 2280155 features an M10 stud connection, a 19 mm palm width, a 15.2 mm internal barrel diameter and an overall length of 60 mm. The barrel incorporates an internal taper to assist conductor insertion and is dimensioned for comfortable positioning between the crimping dies during installation.

Reliable Connections for Reduced-Space Terminal Blocks
Cembre contained-palm copper terminals are specifically developed for applications such as low-voltage circuit breakers where the available terminal-block space is limited. The reduced palm width provides easier access to compact connection points while the carefully engineered copper barrel maintains the electrical conductivity and mechanical strength required for professional power connections.
The A24B-M10/19 combines a 120 mm² conductor capacity with an M10 connection and compact 19 mm palm. Its annealed, tin-plated electrolytic copper construction and internally tapered barrel make it a dependable termination solution for professional switchgear, panel building, power distribution and industrial electrical installations.
Typical Applications
- Low-voltage circuit breakers with reduced-space terminal blocks.
- Electrical control panels and switchgear.
- Power distribution equipment.
- 120 mm² stranded copper conductor terminations.
- Industrial machinery and electrical equipment.
- Panel building and M10 bolted electrical connections.
