50A Insulated Puncture Wire Clip 400V T-Shaped Terminal

The 50A Insulated Puncture Wire Clip is a compact, heavy-duty T-shaped terminal connector designed for fast, secure wire tapping without cutting or stripping. Rated at 400V / 50A, this break-proof clip delivers a solid, insulated connection every time — ideal for automotive, marine, household, and low-voltage electrical projects.

Constructed from a durable plastic + metal composite, the clip features a puncture-style design that pierces the wire insulation to make direct contact — no need to expose bare wire. The T-shaped form factor allows a branch wire to tap off a main line quickly and cleanly, making it a go-to solution for splicing or extending circuits.

Frequently Asked Questions

Q: What wire sizes are compatible with the 50A Insulated Puncture Wire Clip?

A: This T-shaped terminal clip is designed to work with wire sizes ranging from 1 to 6mm² square wire, making it suitable for a wide range of low- to medium-current electrical applications.

Q: How does the puncture wire clip work?

A: The clip uses insulation-piercing teeth to make direct metal-to-metal contact with the conductor inside the wire — no stripping required. Simply press the clip onto the main wire, insert the branch wire into the T-port, and secure the locking cap for a tight, insulated connection.

Q: Is this wire clip safe to use in automotive applications?

A: Yes. Rated at 400V and 50A, and made with a break-proof insulated housing, this clip is well-suited for automotive, marine, and other 12V–48V DC systems. Always verify your specific circuit's current and voltage requirements before installation.

Q: What is the clip made of?

A: The 50A Insulated Puncture Wire Clip is constructed from a combination of durable plastic and metal components, measuring 2.6 × 2.1 cm. The plastic housing provides insulation and mechanical protection, while the metal contacts ensure a reliable electrical connection.
