serviceklemme

A serviceklemme is a clamp-like electrical connector used to temporarily connect, secure, or bridge conductors or lines during servicing and maintenance. It is employed in several sectors, including electrical engineering, automotive service, and HVAC installations, wherever a quick, non-permanent interface is required between equipment and a circuit or line.

Construction and variants: Serviceklemmen typically consist of metal jaws forming a contact, operated by a spring or screw mechanism, and housed in an insulating body or handle. They come in various sizes to fit different conductor diameters or tubing. Some designs resemble an alligator clip, while others are plug-in terminal clamps that snap onto a terminal or busbar. Many are color-coded or rated for specific voltage and current ranges, and some include insulated handles for safety.

Operation and applications: During maintenance, a technician attaches the clamp to a conductor, terminal, or line to establish a temporary electrical contact, ground, or feed a test instrument. In mechanical or plumbing contexts, a service clamp may secure hoses or pipes temporarily to hold components in place during assembly or service.

Safety and limitations: Serviceklemmen are intended for temporary use and should be selected to match the expected electrical or mechanical load. They should be used according to manufacturer instructions and relevant safety standards; improper use can cause arcing, short circuits, or mechanical damage.
