Genuine Siemens MD63B700 – 700A 3 Pole Molded Case Circuit Breaker

Designed for robust industrial distribution, this 700A molded case breaker delivers 50kAIC interrupting capacity at 480VAC. The MD6 frame utilizes a thermal-magnetic trip unit with adjustable magnetic settings to fine-tune short-circuit response. It installs seamlessly into Siemens motor control centers, SB switchboards, and FPP panelboards. While currently active, facilities planning future transitions can migrate to the newer 3VA65 series utilizing an approved manufacturer retrofit kit.
