Description
Providing high-capacity overcurrent protection, the Siemens CE3B040 is a 3-pole, 40A current-limiting MCCB. It belongs to the legacy Cordon family, utilizing thermal-magnetic trip units alongside Amp-Trap limiters. This bolt-on breaker fits seamlessly into Siemens P2 and P3 panelboards. It is an ideal exact-match replacement for older facilities, avoiding the need for panel modifications. It is replaced by the CED63B040. The 100kAIC rating at 480VAC ensures excellent downstream protection.Specifications

Product FAQs
5 answersWhat panelboards accept the CE3B040 circuit breaker?
This bolt-on breaker is designed for installation in Siemens P2 and P3 panelboards, as well as compatible Siemens switchboards.
What wire sizes are supported by the terminals on this breaker?
The factory lugs accommodate 8 AWG to 4 AWG conductors and are rated for both copper and aluminum wiring.
Does the CE3B040 provide current limiting protection?
Yes, this CE frame breaker is current limiting. It offers high interrupting capacities, including 100kAIC at 480VAC and 200kAIC at 240VAC, to protect downstream equipment from severe fault currents.
Will I receive an ITE or Siemens branded breaker?
Because this is a legacy C frame MCCB, it may feature either ITE or Siemens branding depending on when it was manufactured. Both versions share the exact same form factor and electrical ratings.
Are the trip settings adjustable on the CE3B040?
No, this breaker utilizes a thermal magnetic trip unit with fixed thermal and fixed magnetic settings for its long-time and instantaneous protection functions.
