Product FAQs
8 answersWhat enclosures and panelboards are compatible with the HND63B120?
This 1200A breaker is designed for use in Siemens P4 and P5 panelboards, as well as Siemens switchboards and Sentron enclosures. It utilizes a unit mount, feed-thru connection.
What wire sizes and materials are accepted by the lugs on this breaker?
The factory lugs accept four 250 to 500 kcmil copper or aluminum conductors per phase. Ensure proper torque specifications are followed during installation as outlined by Siemens.
How does the trip unit function on the HND63B120?
This breaker features a thermal magnetic trip unit with fixed thermal and adjustable magnetic settings. It provides long-time and instantaneous (LI) protection functions for the circuit.
Are the trip settings adjustable on the HND63B120?
Yes, the magnetic (instantaneous) trip setting is adjustable, allowing you to fine-tune short-circuit protection. The thermal (long-time) setting is fixed at 1200A.
Can this breaker be used in DC applications?
Yes, the HND63B120 is rated for DC systems. It provides an interrupting capacity of 50kA at both 250VDC and 500VDC.
What is the difference between the HND63B120 and the ND63B120?
The HND63B120 is the high-interrupting version of the standard ND63B120. While they share the same physical footprint and 1200A rating, the HND63B120 offers a higher interrupting capacity of 65kA at 480VAC compared to the standard 50kA rating of the ND63B120.
What is the difference between the HND63B120 and the HNXD63B120?
The HND63B120 features an interchangeable trip unit, while the HNXD63B120 is built with a non-interchangeable trip unit. Both are 1200A, 3-pole breakers with the same physical dimensions and high interrupting capacity.
What frame size is the HND63B120?
This breaker belongs to the Siemens ND frame family, specifically the HND frame type, which designates its high interrupting capacity. It shares the same physical footprint as other ND-frame breakers.
