Why Choose the Partex RR32/RA M3 Red Insulated Ring Terminal?
The Partex RR32/RA is a red insulated M3 ring crimp terminal designed to provide secure electrical connections between stranded copper conductors and screw or stud terminals. Featuring a closed-ring connection and an insulated crimp barrel, this terminal is suitable for professional electrical installation, control panel wiring and industrial equipment assembly.
As part of the Partex insulated ring terminal range, the RR32/RA provides a practical and reliable solution for electricians, panel builders and maintenance engineers. Its ring-shaped connection is designed to fit an M3 fixing stud or screw, helping retain the terminal securely when the connection is correctly tightened. The red insulation provides convenient identification and helps protect the crimped conductor entry.
Designed for use with small stranded copper conductors, the RR32/RA features the standard red insulated terminal size designation, commonly associated with a 0.5–1.5 mm² conductor range. Supplied in a pack of 100, these M3 ring terminals are ideal for electrical wiring, equipment maintenance, terminal connections and professional cable assembly applications.

Ring terminals provide a secure method of connecting electrical conductors to screw or stud-mounted connection points. The Partex RR32/RA features a closed-ring design intended for M3 fixings, allowing the terminal to be retained beneath the fixing head or washer. Unlike open-ended fork terminals, a ring terminal normally requires the fixing to be removed before the terminal can be disconnected.
The insulated crimp barrel is designed to accommodate a suitably sized stranded copper conductor. When the conductor is correctly stripped and compressed using an appropriate crimping tool, the terminal provides a mechanically secure connection. The red insulation helps identify the terminal size range and provides additional protection around the conductor entry.
The RR32/RA uses the standard red insulated terminal colour designation, commonly associated with conductors of 0.5–1.5 mm². For dependable installation, the correct conductor size, crimping tool and fixing arrangement must be selected. The electrical current capacity of the completed connection depends on the terminal rating, conductor size, connection hardware and operating conditions. All connections should be tightened according to the equipment manufacturer's requirements.
Typical Applications
