Does the QP2B030 replace the Siemens Q230 or Murray MP230?
Yes, the QP2B030 is a direct equivalent to the Siemens Q230 and the discontinued Murray MP230. It provides the same 30A, 2-pole protection and fits the exact same load centers.
What wire sizes are accepted by the lugs on this 30A breaker?
The terminal lugs accept 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Always verify the required torque specification printed directly on the breaker label during installation.
Is the QP2B030 HACR rated for HVAC equipment?
Yes, this thermal magnetic circuit breaker is HACR rated, making it suitable for use with heating, air conditioning, and refrigeration equipment that requires a 30A, 2-pole breaker.
What applications is this 120/240V breaker suitable for?
The QP2B030 is designed to supply 240V to heavy-draw appliances like water heaters and condensers, or 120/240V to equipment requiring two hot legs and a neutral connection.
Will this breaker fit in older ITE or Gould panels?
Yes, the QP2B030 features a standard plug-on mounting style that is fully backward compatible with legacy ITE and Gould load centers designed for QP series breakers.
How many panel spaces does the QP2B030 require?
As a 2-pole miniature circuit breaker in the QP series, it requires two standard 1-inch spaces in the load center.
What type of protection does the LI trip function provide?
The thermal magnetic trip unit includes Long-Time (L) protection to prevent damage from sustained overloads, and Instantaneous (I) protection to quickly clear severe short circuits.
