## Summary description

Negative battery terminal clamp IWH 019040 with integrated circuit breaker, designed for cars and caravans. Provides a secure negative connection to the vehicle battery while offering overcurrent protection via the built-in breaker. Suitable for standard 12V automotive systems, it simplifies installation and improves safety during maintenance or temporary power disconnection.

## Long description

Negative battery terminal clamp IWH 019040 with integrated circuit breaker is designed for secure connection to 12V vehicle negative battery posts in cars and caravans. The clamp provides a stable electrical contact while the built-in circuit breaker offers overcurrent protection and a convenient manual disconnect for maintenance or temporary power isolation. Constructed for straightforward installation, the clamp adapts to standard automotive battery posts and supports routine vehicle and leisure-vehicle electrical tasks.
Advantages
The combined clamp and circuit breaker reduces the need for separate inline protection and simplifies wiring by integrating overcurrent protection directly at the negative terminal. Its compact design saves space in tight battery compartments and the manual reset capability of the breaker allows quick restoration of power without replacing fuses. Durable materials ensure consistent contact and resistance to vibration common in automotive and caravan environments.
Suitable for
12V car electrical systems requiring a secure negative terminal connection
Caravans and motorhomes where temporary power isolation is needed during maintenance or storage
Situations where integrated overcurrent protection at the battery terminal is preferred
Electrical upgrades or repairs that benefit from a removable negative connection
Key specifications
Designed for standard 12V automotive electrical systems
Negative terminal clamp compatible with common battery post sizes
Integrated circuit breaker providing overcurrent protection and manual reset
Robust construction for vibration resistance and reliable contact
Compact form factor suitable for tight battery compartments
How to use
Park the vehicle on a level surface and switch off all electrical consumers before beginning. Loosen and remove the existing negative terminal clamp, ensure the battery post is clean and free of corrosion, then attach the IWH negative clamp firmly to the negative post. Tighten the clamp connection to secure electrical contact. Connect the vehicle negative cable or ground lead to the clamp’s terminal point following manufacturer torque recommendations. Test the circuit breaker by switching it to the on position; if the breaker trips under fault conditions, reset it manually once the fault has been resolved.
Usage recommendations
Use this clamp in 12V systems only. Inspect connections periodically for corrosion and tightness, especially after off-road use or extended vibration. Replace any damaged cables or terminals before use. If the circuit breaker trips repeatedly, diagnose the underlying electrical fault rather than repeatedly resetting.
