## Summary description

Auto reset circuit breaker BLOW 3767# rated at 40 A for automotive electrical protection. Designed to protect wiring and electrical components from overloads by interrupting and automatically restoring the circuit when fault conditions clear. Compact in-line design suitable for cars, trucks, boats, and other 12V/24V vehicle systems where repeated resettable protection is required.

## Long description

The BLOW 3767# Auto Reset Circuit Breaker is a compact, in-line protective device rated for 40 A and designed for automotive electrical systems operating at 12 V or 24 V. It interrupts current flow when an overload condition occurs and automatically restores the circuit after the fault clears and the device cools. The unit provides repeatable trip-and-reset protection for wiring runs, accessories and electrical components in cars, trucks, boats and other mobile applications where space is limited and reliable resettable protection is required.
Advantages
This auto reset circuit breaker offers thermal-magnetic protection without the need for manual replacement after a trip, reducing downtime and maintenance. Its compact in-line form factor allows installation directly in wiring harnesses or near protected loads, saving panel space. The device is suitable for repeated trip cycles and provides consistent performance for overload protection of alternators, auxiliary circuits, lighting, pumps and other vehicle electrical equipment.
Suitable for
 Automotive accessory circuits (lights, audio, chargers)
 Truck and commercial vehicle electrical protection
 Marine and boat 12 V/24 V systems for bilge pumps and navigation equipment
 Off-road and recreational vehicles with exposed or extended wiring runs
Key specifications
 Rated current: 40 A
 Operating voltage: designed for 12 V and 24 V vehicle electrical systems
 Protection type: auto-resetting thermal overload breaker
 Form factor: compact in-line design for wiring harness installation
 Reset behavior: automatic restoration of circuit after cooldown when overload condition is removed
How to use
Install the circuit breaker in series with the load you intend to protect, ensuring correct wire size and secure terminal connections. Mount the unit in a location protected from direct water spray and excessive heat but accessible for inspection. When an overload occurs the breaker will open the circuit; after the protected circuit is cleared and the device cools, it will automatically reset and restore power. Verify compatibility with the vehicle's system voltage and typical operating currents before installation.
Usage recommendations
Use appropriate gauge wiring and corrosion-resistant terminals for the rated 40 A current to maintain reliable operation. Avoid installing the device in locations with continuous high ambient temperatures or direct engine heat sources. If tripping occurs repeatedly under normal expected load, investigate the circuit for faults or excessive current draw rather than relying on repeated auto-resets.
