Why Choose the Partex RR53/RA M5 Red Right-Angled Ring Terminal?
The Partex RR53/RA is a professional red pre-insulated right-angled ring crimp terminal designed for secure electrical connections to M5 threaded studs and terminal posts. Suitable for 0.5–1.5 mm² copper conductors, this terminal combines a conductive metal ring with durable PVC insulation and a right-angled connection configuration for practical cable termination in electrical equipment and control systems.
As part of the Partex pre-insulated ring terminal range, the RR53/RA features a 5.3 mm ring hole suitable for M5 fastening hardware. Its right-angled design provides an alternative cable connection arrangement where equipment layout, cable routing or terminal access makes a conventional straight ring terminal less convenient.
Supplied in a pack of 100 terminals, the RR53/RA is suitable for electricians, panel builders, equipment manufacturers and maintenance engineers. The combination of red PVC insulation, copper terminal construction and crimp termination makes it a practical solution for reliable bolted electrical connections in industrial and commercial wiring applications.

Reliable Right-Angled Ring Connections for Electrical Installations
Pre-insulated ring terminals provide a secure method of attaching electrical conductors to threaded studs, terminal posts and bolted connection points. The Partex RR53/RA is designed for 0.5–1.5 mm² copper conductors and incorporates a right-angled ring configuration to accommodate installations where the conductor must approach the fastening point from a different direction.
The terminal is attached to a suitably prepared conductor using an appropriate crimping tool. Once crimped, the 5.3 mm ring hole fits over an M5 stud and is secured using the appropriate fastening hardware. The enclosed ring design helps maintain mechanical retention when correctly installed, while the red PVC insulation protects the wire termination area and provides visual identification of the conductor size range.
Typical Applications
- Electrical control panel wiring and assembly.
- M5 terminal stud and bolted electrical connections.
- Industrial machinery and automation equipment.
- Low-voltage electrical distribution assemblies.
- Switchgear and electrical equipment wiring.
- Compact installations requiring right-angled cable routing.
- Electrical equipment manufacturing, maintenance and repair.
