HEX Narrow Palm Circuit Breaker Lugs & Long Palm Long Barrel Copper Lugs

Circuit-breaker terminals often leave little room for a standard lug. HEX narrow palm circuit breaker cable terminal ends (HNP, 35–300 sq mm) have a slim palm that fits MCCB and ACB terminals, and HEX long palm long barrel cable terminals (HCPB, 16–630 sq mm) combine a long flat palm with a long crimp barrel. Both are tinned E-copper. Made by HEX, the brand of Brass Copper & Alloy (I) Ltd., Mumbai — an ISO 9001 company whose products are tested by CPRI (India), UL (USA), KEMA (Netherlands) and SIRIM (Malaysia).

• Economy range — the same job for 35–1000 mm² where a lighter lug is acceptable.
• Bell mouth — flared entry for fast insertion of flexible or fine-stranded conductors.
• Without inspection hole — sealed barrel for damp or outdoor locations.
• Long barrel, 2-hole or 4-hole — longer crimp or anti-rotation palm for heavy terminations.
• 33 kV terminals — for HV cable terminations.
