Switching and protection integrated in single breaker

10 August 2005 Switches, Relays & Keypads

Tyco Electronics' W51 series is a thermal circuit breaker that doubles as a power rocker switch. When specified with its optional indicator lamp, a single Tyco Electronics W51 circuit breaker can replace three components in a piece of equipment, permitting a reduction in component count, assembly time and cost.

The compact, trip-free, rocker-actuated design is rated for 5-20 A. It is suitable for a wide range of applications in household goods, fitness equipment, office machines and industrial equipment.

The W51 is designed to snap into the same cutout as many common power switches. Standard 6,35 mm quick connect tabs are used for wire termination. The breakers can carry 100% of their rated capacity continuously and will trip between 101% and 134% of capacity. At 135% of rated capacity, the W51 is designed to trip within one hour.

Tyco's W51 circuit breakers have an interrupt capacity of 1 kA per UL 1077 and have a resettable overload capacity of 10 times the rated current. Reset time is 60 seconds.
