Providing essential electrical safety, the Siemens E63B030 is a 3-pole, 30A molded case circuit breaker delivering precise long-time and instantaneous (LI) trip responses. This legacy E-Frame component features a unit-mount design tailored for Siemens P1, P2, and P3 panelboards. It serves as an exact fit for older infrastructure and is officially succeeded by the ED63B030. Capable of interrupting 65kA at 240VAC, it meets rigorous industrial standards and is HACR rated for HVAC circuits.
Which panelboards are compatible with the Siemens E63B030?
This legacy E-frame breaker is designed for use with Siemens P1, P2, and P3 panelboards. Verify your specific panel interior accepts E6 frame bolt-on breakers before installation.
How does the E63B030 mount into the panel?
This is a unit-mount, bolt-on circuit breaker. It requires bolted connections directly to the panelboard bus, providing a secure, vibration-resistant installation typical in commercial and industrial environments.
What size wire is required for the lugs on this breaker?
The factory lugs on the E63B030 are sized specifically to accept 10 AWG wire for both copper (Cu) and aluminum (Al) conductors. Ensure your wiring matches this specification for a secure and code-compliant installation.
Can the E63B030 be used in direct current (DC) applications?
Yes, this thermal-magnetic breaker is rated for DC use. It supports up to 250VDC with a 30kA interrupting capacity (30kAIC), making it suitable for industrial DC control circuits and specific solar applications.
Does this breaker provide arc-fault (AFCI) or ground-fault (GFCI) protection?
No. The E63B030 features standard thermal-magnetic trip functions (Long-Time and Instantaneous) to protect against overloads and short circuits. It does not provide specialized AFCI or GFCI personnel protection.
