Description
Built for heavy-duty commercial applications, the CED62B040 is a 40-amp, two-pole current-limiting molded case circuit breaker. It provides exceptional fuseless short-circuit protection by restricting let-through energy, effectively shielding sensitive downstream components. This bolt-on MCCB mounts into Siemens Sentron panelboards. While succeeded by the 3VA series which requires a retrofit, this ED frame remains a direct fit for existing setups, delivering 200kAIC at 480VAC.Specifications

Product FAQs
6 answersWhat panelboards are compatible with the CED62B040 circuit breaker?
This ED frame breaker features a bolt-on connection designed specifically for Siemens Sentron P1, P2, and P3 panelboards, as well as compatible switchboards.
Is the CED62B040 still manufactured, or is there a replacement?
The CED62B040 is part of the legacy Sentron ED frame family, which has been succeeded by the Siemens 3VA series. However, upgrading to a 3VA breaker requires a retrofit kit, making the CED62B040 the preferred direct replacement for existing installations.
What does it mean that the CED62B040 is a current limiting breaker?
As a current limiting breaker, it provides fuseless short-circuit protection by rapidly restricting let-through energy during a fault. This minimizes thermal and magnetic stress, effectively shielding sensitive downstream components.
What size wire is accepted by the lugs on this breaker?
The standard lugs accept 10 AWG to 1/0 AWG copper or aluminum wire. The standard replacement lug kit for this wire range is catalog number LN1E100.
Can the CED62B040 be used in DC applications?
Yes, this thermal magnetic breaker is rated for direct current applications up to 250VDC, with a DC interrupting rating of 30kA.
Does this breaker feature adjustable trip settings?
No, the CED62B040 features a fixed thermal and fixed magnetic trip unit with long-time and instantaneous (LI) trip functions.
