Product FAQs
6 answersWhich Siemens panelboards are compatible with the ED41B100?
This ED frame breaker is designed for bolt-on installation in Siemens SENTRON P1, P2, and P3 panelboards. It mounts directly to the panel bus using bolted connections.
Can the Siemens ED41B100 replace older I-T-E circuit breakers?
Yes, Siemens acquired I-T-E and continued manufacturing the same ED frame breakers. The Siemens ED41B100 is a direct replacement for the legacy I-T-E ED41B100.
What type of wire can be used with the standard lugs on this breaker?
The factory-installed lugs accept both copper (Cu) and aluminum (Al) conductors ranging from 10 AWG to 1/0 AWG. Ensure proper torque specifications are followed during installation to prevent thermal issues.
Is the ED41B100 suitable for direct current (DC) systems?
Yes, this thermal magnetic breaker is rated for use in DC applications up to 125VDC, providing a 30kA interrupting capacity for DC circuits.
How does the interrupting rating change based on the system voltage?
The breaker provides a 65kAIC rating at 120VAC, but this drops to 22kAIC when applied in a 277VAC system. Always verify the available fault current at the specific installation voltage to ensure compliance.
What precautions should be taken when installing this bolt-on breaker?
Always de-energize the panelboard before installing or servicing bolt-on breakers. Verify that the busbar connections are clean and torque the mounting bolts to the manufacturer specified values to ensure a secure, low-resistance connection.
