Product FAQs
7 answersWhat equipment is the SPCB2000 insulated case breaker designed to fit?
It is engineered for installation in legacy Westinghouse Pow-R-Gear switchboards and motor control centers.
What does the LSIG designation mean on the SPCB2000 trip unit?
LSIG indicates that the electronic trip unit provides adjustable Long-Time, Short-Time, Instantaneous, and Ground-Fault protection. This allows electricians to precisely coordinate the breaker with other protective devices in the system.
Are Eaton, Cutler-Hammer, and Westinghouse SPCB2000 breakers interchangeable?
Yes. Eaton acquired the Westinghouse electrical distribution business, so the SPCB2000 Systems Pow-R Breaker may be found with Westinghouse, Cutler-Hammer, or Eaton branding. They share the same physical frame and mounting dimensions.
How is the SPCB2000 physically installed into a switchboard?
This specific configuration is a unit mount design that bolts directly to the busbar connections within the switchboard or motor control center.
Does the SPCB2000 provide ground-fault protection for industrial systems?
Yes, the integrated electronic trip unit includes a dedicated ground-fault function. This is essential for protecting heavy-duty equipment and meeting safety requirements in 480V and 600V applications.
Can the trip curve parameters be modified in the field?
Yes, the electronic trip unit is fully adjustable. Panel builders can modify the pickup and delay settings for the long-time, short-time, and ground-fault functions to match the specific load requirements of the facility.
What breaker family does the SPCB2000 belong to?
The SPCB2000 is a 2000A frame from the legacy Systems Pow-R Breaker (SPB) family, which features an insulated case design for high-capacity industrial power distribution.
