Siemens Q240H-N is a 40 A, 240 V two‑pole molded‑case circuit breaker from the Siemens Q‑Series (Type QPH) designed for 1‑phase, 120/240 V service. This plug‑in unit provides thermal‑magnetic overload and short‑circuit protection, rated at 22 kA at 240 V, making it suitable for 2‑pole protection in residential load centers and light‑commercial panels that require a 240 V breaker. The Q240H‑N uses molded case construction with plug‑in mounting for compatible Siemens panels; its dimensions are 3 in L x 3 in W x 2 in H. Key specs include a 40 A current rating, 120/240 V AC operation, 2 poles, and plug‑in connection, all aligned with common 240 V branch circuit applications in appropriate panels.
