Condition: New
The Supplementary Protector 100A, 480Vac 3P (B1E3P100) is a three-pole circuit protection device built to safeguard electrical equipment and branch circuits from overload and fault conditions. Rated for 100 amperes and designed to operate within 480 volts alternating current three-phase systems, this supplementary protector delivers dependable interruption of excess current before it can damage connected loads or wiring. Its three-pole configuration allows it to monitor and protect all three phases simultaneously, making it a practical choice wherever balanced three-phase power distribution is in use.
Because it is engineered specifically as a supplementary protector rather than a primary branch-circuit breaker, the B1E3P100 works well as an added layer of defense downstream of main protective devices, reducing nuisance trips at the panel level while still shutting down power to a specific piece of equipment when a fault occurs. This 100A, 480Vac 3P unit is well suited for motor control centers, machine tool panels, HVAC equipment, and other industrial or commercial applications where three-phase loads need dependable overcurrent protection. Specifying a supplementary protector rated for the correct amperage and voltage helps installers avoid downtime caused by unexpected equipment failures or wiring damage.
This 100A, 480Vac 3P supplementary protector is best suited for electricians, panel builders, and facility maintenance teams who need a reliable component for upgrading, repairing, or building out three-phase control panels and equipment enclosures. For anyone sourcing a B1E3P100 supplementary protector to match existing system specifications, this device offers the amperage and voltage rating required to keep three-phase circuits protected and operational.
