A circuit breaker is an automatically-operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker […]
General Electric’s Spectra RMS Molded Case Circuit Breakers have a digital, solid state, RMS sensing trip system with field installable, front-mounted rating plugs to establish or change the breaker ampere rating. Advanced models feature the microEntelliGuard Trip Unit, the newest and most advanced trip unit available in the Spectra line. The microEntelliGuard platform allows users […]
Lovato Electric’s SM1 Series Motor Protection Circuit Breaker is a modern manual motor protector with thermal and magnetic trip releases and high breaking capacity. Motor control and protection is possible up to 15kW within a thermal trip adjustment range from 0.1 to 32A. The magnetic trip indicator avoids dangerous closing operations during short-circuit […]
ABB’s MS132 Series Manual Motor Protector is a three pole protection device with thermal tripping elements for overload protection and electromagnetic tripping elements for short-circuit protection. They are used to switch motors ON/OFF manually, and their protective features ensure cost and space savings, and quick reactions under short-circuit conditions. The MS132 motor protector features […]
Eaton’s XT family of Manual Motor Protectors feature a pushbutton or rotary ON/OFF manual disconnect, Class 10 adjustable bimetallic overload relay and fixed magnetic short-circuit trip capability in one compact unit. They can be used to fill a role in three different applications: manual motor protectors, motor protective circuit breakers, and individual branch motor applications. […]
Circuit breakers are safety devices designed to protect electrical circuits and equipment from damaged caused by excess current. In typical cases, an overload or short circuit will trip a breaker to interrupt current flow. This is the expected behavior of the breaker, but in some cases it is important to know how to check the […]
Altech’s L Series Miniature Circuit Breaker is the first ever combined branch circuit protector and equipment ground fault protector. These breakers feature dual pole switching (live and neutral disconnect), designed to provide protection against short circuits, overlaods, AC ground faults (residual current faults) and pulsating DC ground faults. Available in both AC and […]
ABB’s S500 Series high-performance Miniature Circuit Breakers offer a compact solution to circuit protection with application-specific trip characteristics to provide maximum circuit protection, tailor-made for the end user’s exact needs. These breakers feature thermal-magnetic trip operation according to B and K trip characteristics. With a high breaking capacity and fast breaking time (2.3 […]
Altech’s TR11 Series Sub-Miniature Circuit Breakers are compact supplementary protectors suitable for use in a wide range of low voltage applications, specifically as circuit breakers dedicated to equipment. These circuit breakers are ideal for protecting control transformers, uninterruptible power supplies, power strips solenoids and others against overload conditions. Units are available in a […]
NTE Electronics’ R59 Series Sub-Miniature Circuit Breakers are remarkably compact circuit protection devices used to replace slow blow glass cartridge fuses. Measuring 0.76 inches square and just over 1.5 inches long, these circuit breakers offer robust circuit protection in applications where space is particularly spare. At 25°C, R59 breakers will continuously carry 100 […]
