Customizable 3-Pole Electric Type Circuit Breaker with Overcurrent Protection

Basically, it's a 3-pole vacuum circuit breaker that handles overcurrent and overload situations by using a sensor to trigger a tripping coil, which releases a spring-driven mechanism to separate the contacts fast—arcs get snuffed in vacuum chamber, not in open air.

The unit measures 73mm x 72mm x 80mm, so it's compact for high-speed electric operation breaker, and the drawout contact arm means you can slide it in and out of the mounting base without messing with wiring—pretty handy for maintenance.

We've got CE and RoHS certs on file, and the silver-plated copper contacts are a nice touch for conductivity and oxidation resistance, though if you're looking for a standerd thermal-magnetic breaker for a residential panel, this isn't it—it's built for heavier, 3-phase indutrial setups.

Lead time is usually 2-4 weeks, give or take, and the MOQ is typically 10 units or so, but our company can adjust if you're ordering more—just confirm stock before placing a big batch since we run through these pretty fast.

The vacuum interrupter is the core component here, and it's what makes it relaible over thousands of cycles—no oil or gas to leak, just a sealed chamber that does its job until the contact wear eventually limits its life, which is usually 30,000 operations or more.

Also, the tripping coil activation takes about 30 milliseconds form fault detection, which is tighter tolerance than most electromechanical breakers, so if you're protecting sensitive downstream gear, that speed matters more than the raw interrupting capasity.
