At Autosport Engineering, E-T-A Circuit Breakers will be displaying a range of electrical circuit protection solutions.

This includes battery-isolation switches, colour-coded, resettable blade-fuse-style circuit breakers, remotely operated power controllers and high-performance circuit breakers.

The benefit of using circuit breakers in competition cars is the ability to rapidly reset the circuit breaker in the event of an overcurrent.

The E-T-A 911 Battery Isolator Switch offers a reliable alternative to key-operated switches, with remote electrical operation, allowing the switch to be placed near to the battery.

A single-pole momentary switch, located near to the driver, permits rapid disconnection in an emergency.

The colour-coded E-T-A 1610 is a miniaturised version, manual reset, blade-type fuse replacement designed specifically for automotive vehicles.

The E-T-A 1170 is a full-feature, manual reset, blade-type fuse replacement.

This has colour coding of the manual release actuator.

Both models are suitable for plug-in mounting in standard automotive blade-type fuse receptacles, or can be fitted to purpose-designed E-T-A six- and eight-way modular mounting bases.

The E-T-A E-1048-8xx Smart Power Relay is a remotely operated electronic power controller that combines the capability of an electronic switching relay with self-limiting characteristics and optimised overcurrent protection.

Plugging directly into standard automotive relay sockets, it is suitable for controlling load currents from 1A up to 25A for resistive, inductive or capacitive loads.

Practically insensitive to shock and vibration, its tripping characteristic is similar to that of a quality circuit breaker, providing added protection and avoiding nuisance tripping.

The load circuit is automatically disconnected under specified conditions and can be reset remotely.

The E-T-A 483 Circuit Breaker for Equipment (CBE) is a single-pole, temperature-compensated thermal circuit breaker.

Offering protection up to 35A, the range starts at 1A.

The slightly larger E-T-A 482 offers protection for higher load currents from 1 up to 50A.

Both feature a push/pull on/off actuator with a tease-free, trip-free snap-action mechanism, suitable for the rugged conditions that may be faced during competition.

The E-T-A 483, E-T-A 482 and E-T-A 4120 offer circuit protection for vehicle wiring and components such as fans, fuel pumps, wipers, ignition systems, lights, motors and data-logging systems.

A high tolerance to sudden current surges is inbuilt, reducing the risk of nuisance operation and enabling close matching of cable size to CBE.

This avoids overspecifying the cable size and using a higher-rated fuse.

ETA Circuit Breakers

E-T-A designs and manufactures a broad range of electro-mechanical and electronic products for circuit protection, control and instrumentation, including the world’s largest range of circuit breakers for equipment (CBEs). E-T-A’s product programme also includes highly innovative electronic devices and systems with switching, protection and control functionality; as well as a range of process sensors for flow and level sensing.

E-T-A equipment is specified and installed by a wide variety of industrial OEMs and end-users, with key markets including air, sea and land transport, process control, computers and communications, medical equipment, domestic appliances, machine tools and robotics.

Founded in 1948 and still in private ownership, E-T-A has established itself as market leader in the design, development and manufacture of circuit breakers for equipment protection. E-T-A is an international company with headquarters in Altdorf, Germany, and production facilities in several other countries, together with marketing, sales and technical operations throughout the industrial world. Its European, North American and Far Eastern markets are served by some 1,500 employees.

Quality Assurance
E-T-A products are safety-critical items: when required to do so they must perform reliably and predictably – to protect property and people. E-T-A Quality Management has always been prominent within the organisation, working with other departments to establish the foundations upon which E-T-A’s reputation is based. The E-T-A mark is recognised today as a symbol of reliability throughout the world.
