Siemens Q1515NC Circuit Breaker | 15/15 Amps, 1 Pole, 120V

The Siemens Q1515NC is a reliable and efficient solution for expanding circuit capacity in older residential or light commercial electrical panels. Its black, molded case construction is durable, and it operates with a simple toggle-style switch. The primary difference from a standard Q1515 breaker is its Non-CTL design, which accommodates the physical configuration of pre-1968 panel bus bars. When an electrical fault occurs, the breaker trips to protect the wiring and appliances, and it can be manually reset after the fault is corrected.

Features

• Tandem (Space-Saver) Design: This breaker unit contains two separate 15-amp single-pole circuits in a compact, half-inch frame width per pole, allowing for the addition of circuits in panels with limited space.
  
• Non-Current Limiting (NC): The "NC" designation means the breaker does not have the "circuit total limiting" (CTL) rejection feature and is designed for use in older, non-CTL-rated panels.
  
• Amperage & Voltage Rating: Provides two 15-amp circuits and is rated for 120/240 VAC systems.
  
• Thermal-Magnetic Protection: Features a reliable thermal-magnetic trip unit to offer dual protection against persistent overloads (thermal element) and instantaneous short circuits (magnetic element).
  
• Interrupting Rating: It has a standard 10,000 Amperes Interrupting Capacity (AIC), ensuring safety and compliance with UL standards.
  
• Easy Plug-In Installation: The plug-in mounting style and "Insta-Wire" feature allow for quick and easy installation into compatible Siemens EQ, PL, and ES load centers (check panel labeling for Type QT acceptance).
