Rated 25kAIC at 480VAC, the Siemens ED63B030 is a 3-pole, 30-amp molded case circuit breaker built for demanding industrial environments. It installs into Siemens P1, P2, and P3 panelboards, as well as standard switchboards, utilizing a secure bolt-on mounting style. The breaker features a non-interchangeable thermal-magnetic trip unit for reliable long-time and instantaneous protection.
Which panelboards are compatible with the Siemens ED63B030?
This breaker is designed for use with Siemens P1, P2, and P3 panelboards, as well as standard Siemens switchboards.
Do I need a separate mounting kit to install this breaker in a Siemens panelboard?
Yes, installing an ED-frame breaker into a Siemens panelboard requires the correct ED-frame mounting kit based on your specific panel configuration and whether it will function as a main or subfeed breaker.
What is the difference between the Siemens ED43B030 and ED63B030?
The primary difference is the maximum voltage rating. The ED43B030 is rated for a maximum of 480VAC, while the ED63B030 is rated for up to 600VAC. Both are 30A, 3-pole Sentron ED-frame circuit breakers.
Is the trip unit on the ED63B030 adjustable?
No, it features a non-interchangeable thermal-magnetic trip unit with fixed long-time (thermal) and fixed instantaneous (magnetic) trip settings.
What does the LI trip function code indicate for this breaker?
The LI designation means the breaker provides Long-Time (thermal) protection against continuous overloads and Instantaneous (magnetic) protection against short circuits.
Can the ED63B030 be used in DC electrical systems?
Yes, this breaker is rated for direct current applications, providing an interrupting capacity of 30kAIC at 250VDC.
Are mounting lugs included with the ED63B030?
Yes, the breaker includes standard mechanical lugs that accommodate 14 to 10 AWG copper or 12 to 10 AWG aluminum conductors.
Can the Siemens ED63B030 be reverse fed?
Yes, this breaker uses a standard thermal-magnetic trip unit without line and load markings, making it suitable for reverse-feed installations.
Is the ED63B030 HACR rated?
Yes, this circuit breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment.
