Product FAQs
8 answersCan the Siemens Q3030 be used in a Murray load center?
Yes. Siemens acquired Murray, and the Q3030 is UL listed for use in Murray load centers that accept tandem breakers. It serves as a direct, code-compliant replacement for the Murray MP3030.
What Siemens panels accept the Q3030 tandem breaker?
The Q3030 is compatible with Siemens EQ, Ultimate, PL, and ES series load centers designed to accept QT series tandem breakers. Always verify your panel wiring diagram to ensure it allows CTL tandem breakers in the desired slot.
Is the Q3030 a CTL or non-CTL circuit breaker?
The standard Q3030 is a CTL (Circuit Terminal Limitation) breaker. It features a rejection clip and is designed for newer panels that limit the number of tandem breakers. For older panels requiring a non-CTL breaker, the Q3030NC is required.
Is the Siemens Q3030 HACR rated?
Yes, the Q3030 is HACR rated, making it suitable for protecting heating, air conditioning, and refrigeration equipment circuits that require this specific rating.
How much panel space does the Q3030 require?
The Q3030 is a space-saving tandem breaker that provides two independent 30-amp circuits while occupying only a single 1-inch breaker space in your load center.
What is the difference between the Q3030 and the Q3030NC?
The Q3030 is a CTL breaker with a rejection clip for modern panels, while the Q3030NC is the non-CTL version designed for older panels that do not have physical restrictions on tandem breaker placement.
Can I use this breaker to replace an older ITE or Gould tandem breaker?
Yes. Siemens QT breakers evolved from the ITE and Gould product lines. The Q3030 can be used to replace older 30/30A ITE or Gould tandem breakers in compatible load centers.
Does this breaker provide a common trip for 240V applications?
No. The Q3030 provides two independent single-pole 120V circuits. It does not have a common trip mechanism and cannot be used to supply a 240V multi-wire branch circuit or a dedicated 240V load.
