Description
Built for heavy-duty commercial and marine applications, this 40A circuit breaker provides dependable thermal-magnetic protection. The three-pole device operates at up to 600VAC to defend against overloads and short circuits. The unit bolts securely into Siemens Sentron panelboards and marine enclosures. Facilities upgrading their infrastructure can replace it with the 3VA5140-6ED31-1AA0 model using a retrofit kit. Calibrated for 50°C ambients, it achieves an impressive 65kAIC at 480VAC.Specifications

Product FAQs
4 answersWhat does the "M" in the HHED63M040 catalog number indicate?
The "M" designates that this breaker is calibrated for a 50°C ambient temperature, which is standard for marine applications and high-temperature environments. Standard Siemens ED frame breakers are typically calibrated for 40°C.
What panelboards are compatible with the HHED63M040?
This bolt-on ED frame breaker is designed for installation in Siemens Sentron panelboards and switchboards that accept 3-pole ED frame devices.
Are the trip settings adjustable on the HHED63M040?
No, this breaker features a non-interchangeable thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) trip functions. Siemens ED frame breakers do not support field-adjustable or removable trip units.
Is there a modern replacement for the legacy HHED63M040?
Yes, Siemens is transitioning from the legacy Sentron ED frames to the newer 3VA series. Facilities upgrading their infrastructure can replace this unit with the 3VA5140-6ED31-1AA0 model, though a specific retrofit kit is required when installing the 3VA breaker into an older Sentron panelboard.
