A reliable choice for 20A circuits, this SENTRON series breaker provides essential overcurrent and short-circuit defense. Engineered for DIN rail mounting, the single-pole unit fits easily into commercial enclosures and control panels. It utilizes a fixed thermal-magnetic trip unit and comes equipped with standard lugs for straightforward wiring. Rated for 65kAIC at 240VAC, it delivers high-performance protection. The breaker is HACR, HID, and SWD rated for HVAC and lighting loads.
What is the difference between Siemens BQD and CQD circuit breakers?
Both share the same 1-inch per pole frame size, but they differ in mounting and terminal configurations. The CQD series mounts on a DIN rail or surface and includes lugs on both the line and load ends. The BQD series is designed for panelboards and only includes lugs on the load end.
Is the CQD120 rated for switching lighting loads?
Yes. As a 1-pole 20A breaker, it is SWD (Switching Duty) rated for fluorescent lighting and HID rated for high-intensity discharge lighting. It is also HACR rated for heating, air conditioning, and refrigeration equipment.
Can the Siemens CQD120 be reverse fed?
Yes. Siemens CQD molded case circuit breakers are UL Listed for reverse feed applications.
Can I add a shunt trip or auxiliary switch to the CQD120?
No. Internal accessories such as shunt trips, auxiliary switches, and alarm switches mount on the left side of the breaker and are not supported on single-pole CQD models.
How is the CQD120 secured inside a control panel?
The breaker can be independently mounted onto a standard customer-supplied DIN rail or bolted directly to a backplate or surface.
