Description
Operating at up to 600VAC, this 50A Sentron series breaker delivers extra-high interrupting capacity for industrial power systems. The three-pole device utilizes a non-interchangeable thermal-magnetic trip unit for precise fault response. Installation is straightforward, as the breaker bolts into Siemens P1, P2, and P3 panelboards. It is succeeded by the 3VA series, which requires a mounting kit. A key advantage is its marine-duty certification and 50°C calibration for hot environments.Specifications

Product FAQs
6 answersWhat does the "M" in the HHED63M050 part number indicate?
The "M" signifies that this breaker is calibrated for a 50 degrees Celsius ambient temperature. Standard Siemens ED frame breakers, which typically feature a "B" in the catalog number, are calibrated for 40 degrees Celsius.
Does the HHED63M050 come with both line and load lugs?
Standard Siemens ED frame breakers are supplied from the factory with load side lugs only. If line side lugs are required for your installation, they must be sourced separately or ordered under a part number with an "L" suffix.
Which Siemens panelboards accept the HHED63M050 breaker?
This breaker is compatible with Siemens P1, P2, and P3 panelboards, as well as Siemens switchboards and motor control centers. Proper strap kits or mounting hardware will be required based on the specific enclosure.
Is the Siemens HHED63M050 suitable for reverse feeding?
Yes, standard Siemens ED frame circuit breakers can be reverse connected. This allows power to flow from either the line or load terminals without affecting the breaker's protective functions.
Can the trip unit in the HHED63M050 be swapped out for a different amperage?
No, this breaker is built with a non-interchangeable thermal-magnetic trip unit. The long-time and instantaneous trip settings are fixed at the factory and cannot be adjusted or replaced.
What frame size is the HHED63M050?
This breaker belongs to the Siemens ED frame family. It shares the same physical dimensions and mounting requirements as other ED frame breakers like the ED4, ED6, and HED4, but the HHED6 series provides an extra-high interrupting capacity.
