Product Features

Under normal condition, the working principle of main thermostic bimetal in FTB1 SMCB is the same to the usual circuit breakers, it is used for overload tripping. when there is a short-circuit on a branch circuit breaker, the magnet core in the main current path would tilt the moving contact away from the fixed contact to break the circuit,thus producing the electric arc, and limiting the short-circuit current effectively.

In the maintime,the short-circuit current flow to the supplementary current path, a selective resistor and a selective bimetal are connected in series of the supplementary curret path, limiting the short-circuit current to a few hundred amps.

When the downstream circuit-breaker has tripped because of a short-circuit, the contact tips reclose automatically through a simple spring-type system,ensuring other unaffected branch circuits continue in operation.If a short-circuit occur between the FTB1 and the downstream circuit-breaker, another bimetal release enables short-time delayed tripping,ensuring the contact tips remain in the open position enabling isolating.

We’re looking to build a fighting game scene in the Valley. Ever since Family Fun Arcade in Granada Hills closed in 2012, the Valley FGC scattered. We’re already hosting Skullgirls casuals/tournaments every Friday night, and have met recently hosted the Air Dashers (Guilty Gear Xrd –Revelator-, Guilty Gear XX Accent Core Plus R, Vampire Savior: Darkstalkers 3, Skullgirls, CVS2, and etc.).

We would like to reach out to the Street Fighter and Marvel communities, as Street Fighter V is still very new, and Marvel vs Capcom Infinite is coming out later this year. We’re confident we can be the next hang-out spot in the Valley!

We already have 6 PS4 set ups, 4 PS4 Mad Catz TE2+ Arcade Fightsticks, stream station with 2 mics, and a room in the store dedicated toward FGC event. For non-event days, we will have two PS4s set up with 4 PS4 Mad Catz TE2+ Arcade Fightsticks, ready for use (excluding days where the store is hosting special events). Our store features 3,000 sq. ft. with air conditioning and plenty of parking in the rear. With your support, we aim to go even bigger and even hold a major!
