Electrical Connectors
What is a Connector?
A connector is an electromechanical device used to join two electrical parts together, generally this would be connecting a cable to a system or cable to another cable within an electrical circuit. There are many different types of connectors that can accomplish this. They can be used to connect power, data and fibre and can come in different shapes, sizes and materials. They can also be waterproof, dustproof and heat proof to various industry ratings. Our sales team is ready to help you with any queries.
What Do We Supply?
We offer a broad range of electrical connectors, including:
Appliance couplers
Hazardous area connectors
'Buccaneer' sealed connectors
General purpose connectors and accessories

Schurter Three-Terminal Fuses (STTP) for Battery Systems
Intelligent Fuse Solutions for Battery Systems
Ultra-Low Contact Resistance for High Efficiency
High Contact Reliability for Low Signals
Enhanced Wear Resistance for Long‑Term Contact Integrity
Supports Miniaturization and High‑Power Density Design
The Schurter three-terminal fuses STTP 9550 combine conventional overcurrent protection with an actively triggered overcharge protection function, providing an additional layer of safety for lithium-ion battery systems.
In addition to current-dependent interruption, the integrated trigger terminal enables controlled activation in critical operating conditions. This allows reliable disconnection of charge and discharge paths even in the event of protection IC or FET failure.
Gold-plated terminals ensure low and stable contact resistance, high signal integrity, and excellent corrosion resistance. The compact package supports high-power-density battery pack designs ranging from 1 to 24 cells.
Applications: Typical applications include energy storage systems, power tools, UPS equipment, e-bikes, e scooters, and automated guided vehicles (AGVs). Supported by UL approvals and designed for redundant protection architectures required by modern battery safety standards, three-terminal fuses provide a robust and intelligent protection solution for advanced energy systems.
Schurter PPTC Resettable Fuses: Compact Protection for Maximum Reliability
PPTC: Compact Protection for Maximum Reliability
The new PPTC series PFTA, PFTB, PFTC and PFTL provide reliable resettable overcurrent protection for modern electronic applications. In the event of a fault, the polymer PTC device automatically increases resistance to effectively protect systems against overloads and short circuits — without replacing fuses.
The portfolio includes radial leaded and SMD versions with current ratings from 0.05 to 5 A and voltage ratings up to 72 V. UL-compliant flame-retardant materials and compatibility with automated assembly processes make these series ideal for industrial high-volume applications.
Applications: Typical applications include energy storage systems, power supplies, industrial electronics, consumer electronics, automotive systems, wearables, SSDs and Li-ion batteries. The compact PFTL SMD series additionally enables space-saving designs with high integration density.
