Fuses

The 3AB 125-R device is considered an important fuses device in electrical applications. This device can be used to protect circuits against overloading or short circuits in home and commercial applications, such as in buildings, HVAC systems, and air conditioning. It is designed to quickly open the circuit to prevent further damage, which can be caused by a sudden surge in power or overcurrent from electrical sources, or from circuitry that is unstable or faulty.

Application Field

The 3AB 125-R device is designed for use with UL approved industrial and residential circuits that are protected from overcurrent or short circuit conditions up to 125 amperes. It is commonly used in applications such as circuit breakers, motor overload protection, machinery start and stop, and other light industrial or commercial applications. The device also has UL listing and CSA certification for industrial and residential applications. The device is also suitable for standard AC power lines.

Working Principle

The 3AB 125-R device is an electrical fuse device that works by automatically breaking the circuit when there is an overcurrent or short circuit condition. The device contains a small glass capsule that breaks once the electrical current reaches a predetermined level. This causes the device to quickly open the circuit to protect it from further damage. The device also contains a UL-listed indicator that shines when the circuit is open, signaling a potential problem.

The 3AB 125-R fuse is designed to be very reliable and to meet the safety requirements of UL and CSA. It also has an anti-arcing feature that prevents it from re-closing in the event of an intermittent surge. The device is designed to withstand high mechanical stresses during installation and operation, as well as other environmental conditions, such as extreme temperatures, vibrations, shock, and moisture.

The 3AB 125-R fuse is designed to be easy to install and reliable in performance. It can be used in a variety of applications in homes and commercial spaces. It is an important device that helps protect circuits from overcurrent and short circuit conditions, and it is a reliable device that meets the required safety standards.
