W52 Rocker-Actuated Circuit Breakers

TE Connectivity's (TE) / Potter & Brumfield W52 Rocker-Actuated Thermal Circuit Breakers/Power Switches provide trip-free cycling, 0.5A to 20A voltage ratings, and a snap-in panel-mount design that simplifies installation. These compact devices snap into the same cutout as many common power switches and are available with an optional indicator lamp. The W52 series offers ratings of 0.5A to 20A, a quick 60s reset time, and a 1000A interrupt capacity per the UL 1077 standard. The robust construction combines circuit protection and power switching in a single unit with an endurance of 6000 switch cycling operations at 100% of rating. The rocker-actuated design features 0.250" (6.35mm) quick-connects, solder terminals, or right-angle PC terminals, and an operating temperature range of 0°C to +50°C or +60°C. These W52 circuit breakers from TE / Potter & Brumfield can be used in a wide variety of applications.
