ABB Bolt On Miniature Circuit Breakers

Wide range of miniature circuit breakers (MCBs) used to provide electrical safety during current overload and short-circuit conditions. Feature two tripping mechanisms: one for overload protection and the second for short circuit protection. IEC, UL & CSA listed design

ABB S203 Series miniature circuit breakers provide fast action current limiting protection to electrical appliances such as panelboards, switchboards, busway plug-in units and combination starters. These miniature breakers feature a dual tripping mechanism with thermal-magnetic trip unit for providing both instantaneous and time-delayed protection and DIN rail mounting for easy installation. They also allow reverse feeding and come equipped with finger-safe / multi-functional terminals with a bus-type network for secure connection. Choose from a wide range of these circuit breakers, available in 0.2A to 63A current ratings with 240VAC or 480VAC voltage options on Raptor Supplies.

ABB T3 Series circuit breakers are designed for protection of electrical equipment against short-circuit and overload occurrences. These UL-listed breakers feature a bolt-on mounting design to ensure ease-of-installation in compact spaces and a thermal-magnetic trip for delivering LI (Long-time and Instantaneous) current limiting functions. They are capable of delivering interrupting capacities of 25kA at 480V and 35kA at 480V and are available in triple-pole configuration on Raptor Supplies.

ABB T2 Series circuit breakers are designed for limiting let-through currents to protect downstream components in power distribution applications. These molded case circuit breakers feature line & load side lug terminals for eliminating loose connections while ensuring hassle-free wiring. They are equipped with a non-interchangeable thermal magnetic trip that provides both instantaneous & long time trip functions for reacting against severe short-circuits at once while avoiding tripping on mild overloads. They have bolt-on design for ease-of-installation. These triple pole circuit breakers are available in amperage ratings ranging from 15 to 100A on Raptor Supplies.

ABB miniature circuit breakers are designed for limiting let-through currents to protect downstream components in power distribution applications. These UL-listed, supplementary protectors feature DIN rail mounting design & finger safe terminals for ease-of-installation & user safety and lug terminals for eliminating loose connections while ensuring hassle-free wiring. The thermal magnetic trip provides both instantaneous & long time trip functions for reacting against severe short-circuits at once while avoiding tripping on mild overloads. These double pole, bolt on circuit breakers are available in amperage ratings ranging from 0.2 to 63A on Raptor Supplies.

ABB T5 Series molded case circuit breakers safeguard electrical circuits and equipment from overcurrents, preventing damage and ensuring safety. They have a stable and secure electrical infrastructure, enhancing operational efficiency and minimising downtime in electrical distribution systems, industrial plants and commercial buildings. These MCCBs are designed with double insulation, enhancing safety and minimising risks associated with electrical faults. They feature positive operation, ensuring precise positioning of moving contacts through their toggle mechanism. These Tmax MCCBs can be installed horizontally or vertically in panels & switchboards without any performance derating.

ABB T4 Series circuit breakers are designed to provide electric circuit protection against damages caused by overload and short-circuit conditions. These devices feature an electronic trip unit for delivering short-time, long-time and instantaneous current limiting functions and a solid-state protection system for electronically controlling the current flow. They are further integrated with a bolt-on mounting facility for quick and easy installation and line- & load-side lug terminals for a secure wiring configuration. Choose from a wide array of these circuit breakers available in interrupting capacities of 100kA at 480V, 25kA at 480V, 35kA at 480V and 65kA at 480V on Raptor Supplies.
