ABC-1-1/2-R

Fuses are safety devices designed to protect electric circuits from damage due to excessive current. The ABC-1-1/2-R is a type of fuse designed for use in industrial and commercial applications. Its primary purpose is to protect power supplies, motors, starters and other devices from being damaged by excessive overloads.

The ABC-1-1/2-R is a cylindrical, ceramic body cartridge fuse with a threaded base. It has an interrupting capacity of up to 10 kiloamperes and can be mounted in standard fuse boxes. It is rated for 600 volts AC and 250 volts DC. It also has two different types of operating characteristics: the “slow blow” type trips at a current level that is lower than the “fast blow” type but takes longer to open.

The ABC-1-1/2-R works by containing an internal metal wire that is designed to melt and break the circuit under excessive current flow. The wire begins to heat up when the current flow is exceeded and eventually reaches a melting point. This causes the wire to break which in turn interrupts the current flow and thus protecting the circuit from further damage.

The device is usually connected in series with the circuit and thus is not intended for use as a main disconnect device. It should only be used as an overcurrent protection device. It should be sized appropriate for the application to ensure that it can trip at the desired current level without nuisance tripping at lower levels.

The ABC-1-1/2-R is a reliable and cost-effective industrial and commercial fuse with a high interrupting capacity. It should be used in accordance with the manufacturer’s instructions and best practices. It is suitable for a wide range of applications including motor control, power supplies, starters, motor control and other similar applications requiring overcurrent protection.
