The SIEMENS EBF1 is a 1-inch filler plate designed to cover unused breaker slots in compatible Siemens EB-series loadcenters and electrical panels. This blank filler keeps open knockouts covered, maintaining the enclosure's integrity and helping meet NEC requirements for closed electrical panel openings. At 0.309 pounds and measuring approximately 2.756 inches long by 0.787 inches wide by 0.787 inches tall, it is a compact, single-slot cover sized for standard 1-inch breaker positions. Electricians use this filler when a panel position is not occupied by a circuit breaker and must be sealed against accidental contact and debris.
This filler plate is used in residential and light commercial electrical panel installations wherever an EB-series Siemens loadcenter has an unused single-pole breaker slot. It is a standard maintenance and installation item that keeps panels code-compliant after circuit changes, upgrades, or when a breaker position is left unused following a service call.
Designed as an OEM-style filler for Siemens EB-series loadcenters with standard 1-inch breaker slot openings. No additional compatible model numbers were specified in the available product data.
Installation is performed by a licensed electrician. Always de-energize the panel and verify zero voltage with a meter before working inside any loadcenter. Insert the filler plate into the unused slot opening per panel manufacturer guidance. Ensure all unused openings are covered before closing the panel door to maintain compliance with NEC requirements for enclosed electrical equipment.
