## Summary description

Doerr circuit breaker model 787-1668/000-004 is a protective device for DC systems with rated voltage 24 V DC and adjustable or specified current range 2–10 A. Intended for overcurrent protection in industrial control panels, automation equipment and electrical installations where compact, DIN-rail compatible protective switching is required.

## Long description

Doerr circuit breaker 787-1668/000-004 is a compact protective switching device designed for 24 V DC systems with an adjustable current range of 2–10 A. Developed for installation on DIN rails, this circuit breaker provides overcurrent protection in control cabinets, automation equipment and other DC electrical installations where space efficiency and reliable intervention are required. The product is intended for line protection and fault isolation in low-voltage direct current applications.
Advantages
The breaker combines a small footprint with a clear adjustable tripping range, allowing flexible setting between 2 and 10 amperes for various circuit requirements. Its DIN-rail compatible housing simplifies mounting in industrial control panels and distribution boards. The device offers rapid response to overcurrent conditions to protect wiring and connected components, reducing the risk of damage and downtime. Construction and terminal layout are optimized for straightforward wiring and maintenance.
Suitable for
Overcurrent protection in 24 V DC control cabinets
Protection of automation controllers, relays and sensors
Distribution circuits in machine control and production lines
Retrofit or new installations that require compact DIN-rail breakers
Key specifications
Rated voltage: 24 V DC
Adjustable current range: 2–10 A
Mounting: DIN-rail compatible housing
Function: overcurrent / short-circuit protection for DC circuits
Terminal type: screw or clamp terminals suitable for control wiring
Compact form factor for space-saving panel layouts
How to use
Install the breaker on a standard DIN rail inside the control enclosure and connect the supply and load conductors to the designated terminals, observing polarity for DC circuits. Adjust the tripping current within the 2–10 A range according to the load requirements and short-circuit protection coordination. Verify correct tightening of terminals and ensure clearances meet local installation rules. After wiring, energize the circuit and test the breaker operation under controlled conditions to confirm correct behavior.
Usage recommendations
Use the breaker as part of a coordinated protection scheme; select the tripping setting based on conductor cross-section, maximum continuous load and downstream device ratings.
