Product FAQs
6 answersWhat types of enclosures or panels is the HHED63B045 compatible with?
This bolt-on ED frame breaker is designed for use in Siemens Sentron panelboards, switchboards, and motor control centers. It is not compatible with standard residential load centers that require plug-on breakers.
What wire size do the standard lugs on the HHED63B045 accept?
The factory-installed lugs accommodate 10 AWG to 1/0 AWG copper or aluminum conductors. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
What does the "HH" designation mean in the HHED63B045 part number?
The "HH" indicates that this is a high interrupting capacity version of the Siemens ED frame. It provides higher fault current protection compared to standard ED4 or ED6 breakers, making it suitable for commercial and industrial systems with high available fault currents.
Are the thermal and magnetic trip points adjustable on this model?
No, the HHED63B045 utilizes a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be adjusted in the field.
Can the HHED63B045 be used in DC voltage applications?
Yes, this breaker is rated for use in DC systems up to 250VDC. When used in DC applications, it provides a 30kA interrupting capacity.
What is the recommended safety procedure before installing this bolt-on breaker?
Always de-energize the panelboard or switchboard before installing or removing the HHED63B045. Verify that power is completely disconnected using a properly rated voltage sensing device to prevent arc flash and electrical shock hazards.
