FAQs
Q: Why should I use C45N pin terminals instead of standard ring terminals for circuit breakers?
A: Circuit breakers like the DZ47/C45 series have deep, narrow insertion slots. Ring terminals are too wide to fit. Our C45N pin/needle design is specifically shaped to enter these slots and provide maximum contact surface with the breaker’s internal clamp.
Q: Are these terminals compatible with both aluminum and copper cables?
A: These terminals are made of T2 copper with tin plating, optimized for copper-to-copper connections. While the tin plating helps mitigate galvanic corrosion, we recommend them primarily for high-quality copper wiring to ensure the best electrical performance.
Q: Do I need a special crimping tool for the C45 series?
A: Yes. For the best result, we recommend using a professional hexagonal or point-pressure crimping tool suited for copper tube terminals. This ensures the T2 copper tube is compressed into a solid mass around the wire strands for a gas-tight seal.
