2857.0 - Insulated Industry & DIN Standard : 4 AWG : 25 mm²
Original Industry Standard Ferrules
Ferrules ensure reliable electrical connections when terminations standard wire in terminal block, circuit breakers, or other control devices. Insulated ferrules prevent conductor breakage due to bending, wire stress, or vibration while facilitating wire insertion into the terminal clamp. Altech's insulated ferrules are color-coded by conductor size for identification. To ensure efficient clamping, select the smallest ferrule diameter that fits the wire & use professional crimping tools.
