Product FAQs
6 answersWhat does the "M" in the ED63M050 catalog number indicate?
The "M" designates a 50 degree Celsius ambient temperature calibration. This makes it suitable for industrial or marine applications with higher ambient temperatures, serving as a direct substitute for the standard 40 degree Celsius calibrated ED63B050.
Which panelboards accept the ED63M050 circuit breaker?
This ED-frame breaker mounts into Siemens Sentron panelboards, including the P1, P2, P3, P4, and P5 series, as well as compatible Siemens switchboards designed for bolt-on branch devices.
Are lugs included with this breaker, and what wire sizes do they accept?
Yes, it includes load-side lugs that accommodate 10 to 1/0 AWG copper or aluminum wire. Because it is a bolt-on breaker, the line side connects directly to the panelboard bus without requiring line-side lugs.
Can the ED63M050 be reverse fed?
Yes, this thermal-magnetic circuit breaker features reverse feed capability, allowing flexibility during installation in compatible enclosures.
Can I use the ED63M050 in direct current applications?
Yes, this breaker is certified for DC systems up to 500VDC. When installing in DC environments, ensure your enclosure and bus system are appropriately rated for the direct current interrupting capacity.
Can this breaker replace older I-T-E ED-frame breakers?
Yes, Siemens acquired I-T-E, and the ED63M050 is a direct replacement for legacy I-T-E 50A, 3-pole ED-frame breakers with matching specifications.
