Why Choose the Partex BS37N/RA Blue Insulated Narrow Spade Terminal?
The Partex BS37N/RA is a blue insulated narrow spade terminal (fork terminal) designed for electrical conductor termination using compatible M3.5 screw connections. Its narrow fork configuration makes it particularly useful where terminal space is restricted or a standard-width spade terminal may not fit the available connection area.
Part of the Partex insulated spade terminal range, the BS37N/RA combines a practical open-fork connection with an insulated crimp termination. The fork design allows the terminal to be fitted beneath a compatible loosened screw head without completely removing the screw, helping simplify wiring installation, servicing and replacement.
Featuring an M3.5 nominal mounting size, narrow fork profile, blue insulation and a pack quantity of 100 terminals, the BS37N/RA provides a convenient connection solution for electrical contractors, control-panel builders, machinery manufacturers and industrial maintenance engineers.

Narrow Fork Terminals for Electrical Control and Automation Wiring
Spade terminals provide a convenient method of connecting electrical conductors to suitable screw terminals. Unlike closed-ring terminals, their open-fork design allows the connection to be positioned beneath a loosened screw head. This can be useful when replacing wiring or carrying out maintenance on electrical equipment designed to accept fork-type terminals.
The Partex BS37N/RA differs from a standard-width fork terminal through its narrow M3.5 connection profile. This makes it a practical option for compatible terminal arrangements where the available connection width is limited. The blue insulated sleeve surrounds the conductor entry, while the crimp termination provides a method of attaching the terminal to the selected conductor.
For reliable installation, the conductor cross-section, screw size, fork dimensions, electrical ratings and permitted terminal type must be checked before use. The connection should be crimped using a suitable tool and tightened according to the receiving equipment manufacturer's instructions. Narrow fork terminals should only be used where the terminal arrangement provides adequate retention and electrical contact.

Frequently Asked Questions
What is the Partex BS37N/RA used for?
The Partex BS37N/RA is a blue insulated narrow spade terminal used to connect appropriately sized electrical conductors to compatible M3.5 screw terminals. Its narrow fork profile is particularly useful where the available terminal connection width is restricted.
What is the difference between the Partex BS37N/RA and a standard M3.5 spade terminal?
The BS37N/RA features a narrow fork profile, whereas a standard M3.5 spade terminal has a conventional fork configuration. Both are intended for compatible M3.5 screw connections, but the narrow version is designed for applications where a reduced fork width is required. Exact dimensional compatibility should be checked before installation.
What screw size does the Partex BS37N/RA fit?
The BS37N/RA has an M3.5 nominal mounting size and is intended for compatible M3.5 screw-terminal connections. The receiving terminal must also accommodate the narrow fork profile and provide suitable mechanical retention.
How many terminals are supplied in a pack of Partex BS37N/RA?
Each pack contains 100 blue insulated narrow spade terminals, suitable for electrical installation, control-panel assembly, equipment manufacturing and maintenance applications.
How is the Partex BS37N/RA narrow spade terminal installed?
The conductor is stripped to the appropriate length and inserted into the terminal barrel before being secured using a suitable crimping tool. The narrow M3.5 fork is then positioned beneath a compatible loosened screw head and tightened according to the equipment manufacturer's instructions. The conductor size and terminal compatibility must be verified before installation.
