A combined single pole circuit breaker and 'on/off' switch provides simultaneous switch function and motor and transformer protection in office equipment and electrical tools.
The E-T-A Series 3131 is a combined single pole circuit breaker and ON/OFF switch available from Aerco that is designed to provide function control and circuit protection in a single unit. Designed primarily to provide simultaneous switch function and motor and transformer protection in boats and caravans, they will also be highly suitable for construction vehicles, household appliances, office equipment, electrical tools and medical equipment. Both aesthetically pleasing and functional, the rockers have a highly tactile, soft-touch actuation and are available in either black or blue with legends that cover most of the common functions likely to be required such as 'pumps', 'showers', 'lights' and 'wipers'.

Both switches and breakers can be specified with blue or yellow LED illumination and the switches can be provided with dim illumination when circuit is off and bright when active.

The switches are available in two and three position, either momentary or latching.

Although in most applications the integration of circuit breaker and function switch will simplify panel design, switches without the breaker facility can also be supplied.

The Series 3131 meets the requirements of circuit breaker standard EN 60934 and is sealed to IP66 rated front of panel splash protection.

Voltage rating is 24V AC or 28V DC with a current capability of up to 20A.

The operating temperature range is -20 to +60 deg C and lifetime is 30,000 operations.
