Product FAQs
5 answersHow does the PBF31600PRF achieve its 200kA interrupting rating at 600VAC?
This breaker utilizes 1600PBPR30 replaceable current limiters. These limiters act in series with the breaker contacts to safely interrupt extremely high fault currents up to 200kA across all AC voltage levels, preventing catastrophic equipment damage.
Can the trip settings on this 1600A breaker be modified in the field?
The thermal element for long-time overload protection is fixed at 1600 amps. However, the magnetic instantaneous trip function is adjustable, allowing electricians to coordinate the short-circuit response with downstream devices.
Which Eaton and Westinghouse enclosures accept this PB frame breaker?
The unit mount design is engineered for installation in legacy Eaton and Westinghouse switchboards, motor control centers, and Pow-R-Line panelboards that are configured for PB frame insulated case circuit breakers.
What happens if the breaker clears a massive short-circuit fault?
If a fault exceeds the interrupting capacity of the standard breaker contacts, the 1600PBPR30 current limiters will blow to clear the fault. These limiters must be physically replaced before the breaker can be safely placed back into service.
Is this insulated case breaker suitable for DC power systems?
Yes, it is rated for use in 250VDC applications with a maximum interrupting capacity of 100kA. Ensure your specific DC panelboard or switchgear is designed to accommodate the physical dimensions and lug configuration of a PB frame unit.
