E-T-A Circuit Breakers, quality designer and manufacturer of a broad range of electro- mechanical and electronic products for circuit protection, has introduced a new solid-state power relay offering a noiseless relay function together with electronic overcurrent protection in a single unit, thus minimising the space requirements and the number of plug-in components.
Designed for standard 4-pole automotive relay sockets (to ISO 7588), the E-T-A Electronic Standard Relay ESR10-P ISO Maxi is suitable for 12V DC on-board electrical systems, is rated to 50A and offers remote re-setting in the event of an overload trip. The ESR10 is suitable for a wide range of 12V DC systems, for example switching and protecting motors, lamps and magnetic valves in road, construction, agricultural and rail vehicles as well as for work and leisure boats, and for industrial applications in process and automation. The solid-state design of the E-T-A ESR10 relay offers wear-free switching and is unsusceptible to shock, vibration and dust. Silent switching can bring benefits for applications inside a passenger cabin. It also requires a far smaller closed and switching current compared to a standard electromechanical relay. In the event of a trip through short circuit or overload, the type ESR10-P can simply be re-set remotely by switching it off and on, rather like a re-settable fuse. The type ESR10-N ISO Micro is a smaller version solid-state relay offering short circuit protection only and is rated to 30A.The ESR10-P ISO Maxi is packaged in a 30cm x 30cm x30cm housing and complements the long-established E-T-A E-1048-8 which also combines the capability of a remotely controllable electronic load disconnecting relay with self-limiting characteristics, and optimised overcurrent protection similar to that of a high quality circuit breaker. The E-1048-8 is suitable for wide ranging 12/24V DC applications for protection up to 30A where solenoids, motors or lamp loads have to be switched, protected or monitored, including use in vehicles, on land and sea, in telecommunications, and in the process industry.
