## Summary description

The Qoltec 52590 is a miniature circuit breaker rated at 16A with a breaking capacity class C. It features a single pole design and compact dimensions of 17mm width, 75mm depth, and 86mm height, making it suitable for various electrical applications.

## Long description

The Qoltec miniature circuit breaker model 52590 is a single-pole overcurrent protection device designed for protecting electrical installations and connected equipment from overloads and short circuits. It is intended for DIN-rail (TH35) mounting and is suitable for use in photovoltaic and general electrical installations. The breaker features combined electromagnetic and thermal trip mechanisms for reliable fault detection.
Advantages
The device provides compact, space-saving protection with a clear single-pole design and a Class C breaking characteristic suitable for moderate inrush currents. Its thermal and magnetic trip elements ensure both long-term overload protection and fast interruption of short-circuit currents. DIN-rail mounting makes installation and replacement straightforward in distribution boards.
Suitable for
 Residential electrical distribution circuits
 Photovoltaic system protection (AC side)
 Light commercial and workshop installations
 Protecting individual circuits with motors or equipment that have moderate inrush currents
When it may not be suitable
This single-pole, 16 A breaker with Class C characteristic may not be appropriate for circuits requiring higher continuous current ratings or different trip curves (for example, Class B or D) where inrush or fault conditions differ. It is also not suitable where multi-pole common-trip protection is required for simultaneous disconnection of all poles.
Key specifications
 Rated current: 16 A
 Number of poles: 1 (single pole)
 Tripping characteristic: Class C (magnetic + thermal)
 Mounting: DIN rail TH35
 Width: 17 mm
 Depth: 75 mm
 Height: 86 mm
 Intended use: AC circuits, suitable for photovoltaic installations
How to use
Install the breaker on a standard TH35 DIN rail inside the distribution board, ensuring the supply and load conductors are correctly connected to the input and output terminals. Observe proper tightening torques and wiring practices; switch off upstream power before installation. After mounting and wiring, verify correct operation by switching the breaker on and off and testing the protected circuit under expected load conditions.
What to consider before purchase
 Match the breaker rated current (16 A) to the circuit wiring and expected load.
 Confirm Class C tripping is suitable for connected equipment with inrush currents.
 Ensure single-pole protection meets safety and local code requirements for the intended application.
 Check available panel space for the 17 mm device width and DIN-rail compatibility.
Usage recommendations
Use this Qoltec 16 A Class C miniature circuit breaker for single-circuit protection in residential, light commercial, and photovoltaic AC installations; pair it with appropriate upstream protection and proper wiring to ensure safe operation.
