Đầu nối chạc khóa không cách điện LSNB
LSNB Non-Insulated Lock Fork Terminals are bare copper terminals for bolted conductor connections. The series includes 14 models across 0.5–6 mm² conductor groups.
- Select by conductor section and the model-specific bolt-hole diameter.
- Compare B, F and L as well as barrel dimensions E, D and d.
- Catalog Imax is 19, 27 or 48 A depending on conductor group.
Tổng quan
LSNB Non-Insulated Lock Fork Terminals are non-insulated copper crimp terminals with a fork tip with inward-curving locking ends for a bolted connection. The source lists 14 models across three conductor groups. Each model has a specified bolt number, bolt-hole diameter and B, F and L dimensions.
Tính năng
- Bare copper contact: the catalog identifies copper construction without an insulating sleeve.
- Model-specific fork geometry: B, F and L dimensions are given per model for the listed bolted connection.
- Group-specific barrel dimensions: E, D and d, material thickness and Imax vary by conductor group.
