Tyco Electronics has launched the P&B W51 series thermal circuit breaker that doubles as a rocker switch.

The circuit breaker can replace three components in a piece of equipment when specified with its optional indicator lamp, which reduces component count, assembly time and cost, said the company. Applications include industrial equipment, office machines, household products and fitness equipment.

The unit is designed to fit the same cutout as many common power switches, and standard 6.35mm quick-connect tabs are used for wire termination. The trip-free design is rated for 5A to 20A.

The circuit breakers will continuously carry 100 percent of their rated capacity and may trip between 101 percent and 134 percent of capacity, said the company. They are designed to trip within one hour at 135 percent of rated capacity.

Featuring an interrupt capacity of 1kA per UL 1077, the units have a resettable overload capacity of ten times the rated current. Reset is rated at 60s. A 5A circuit breaker is priced at $1.21 each in quantities of 10,000. Lead time is four to six weeks.
