Product FAQs
5 answersWhich enclosures are compatible with the HMD63B700 circuit breaker?
This unit-mount MCCB is designed for direct installation in Siemens P4 and P5 panelboards, as well as Siemens switchboards and motor control centers that accept Sentron MD-frame devices.
What size wire do the standard lugs on the HMD63B700 accept?
The included factory lugs accommodate up to three copper or aluminum conductors per phase. The acceptable wire range for these terminals is 1/0 AWG to 500 kcmil.
How is the trip unit adjusted on this model?
The HMD63B700 uses a thermal-magnetic trip unit with an LI function profile. The thermal element for long-time overload protection is fixed, while the magnetic element for instantaneous short-circuit pickup is adjustable via a dial on the breaker face.
How does the HMD frame differ from the standard MD frame breaker?
The H in the HMD designation indicates a high-interrupting capacity. This model offers a 65kAIC fault clearing rating at 480VAC, which provides greater short-circuit protection than standard MD frame breakers.
What safety procedures must be followed before replacing or installing this MCCB?
Always disconnect, lock out, and tag out all power sources feeding the switchboard or panelboard. Confirm the equipment is fully de-energized with a properly rated voltage meter before removing any covers or handling the breaker.
