Product information

Description

Miniature circuit breaker QOLTEC 52591 is a single-pole protective device with a 20 A rated current and C-type tripping characteristic. Intended for DIN-rail mounting on TH35 rails, the device combines electromagnetic and thermal trip functions to interrupt overloads and short circuits. Its compact dimensions (17 × 75 × 86 mm) and 17 mm module width make it suitable for installation in residential and light commercial distribution boards to protect lighting, socket circuits and other single-phase loads.

Advantages

The QOLTEC 52591 offers coordinated electromagnetic and thermal protection, ensuring fast response to short circuits and reliable protection against prolonged overloads. Its single-pole design and narrow 17 mm width save space inside distribution panels while providing straightforward manual operation for switching and resetting. The breaker is designed for standard DIN-rail mounting, simplifying installation and replacement in existing switchboards.

Suitable for

Residential electrical distribution boards
Lighting circuits
Socket outlet circuits for appliances and small equipment
Light commercial and workshop electrical installations

Key specifications

Poles: 1 (single-pole)
Rated current: 20 A
Tripping characteristic: C-type (moderate inrush tolerance)
Trip mechanisms: thermal and electromagnetic
Mounting: DIN-rail (TH35)
Width: 17 mm (one-module)
Overall dimensions: 17 × 75 × 86 mm

How to use

Install the QOLTEC 52591 on a standard TH35 DIN rail inside the distribution board, ensuring the supply conductor is connected to the breaker input and the load conductor to the output. Verify the correct polarity and tighten terminal screws to the manufacturer's recommended torque. Use the breaker switch to manually connect and disconnect the circuit; in case of fault the device will trip automatically and can be reset after clearing the cause of the overload or short circuit. Ensure the installation is carried out by a qualified electrician and power is disconnected before wiring.

Usage recommendations

Choose the QOLTEC 52591 for single-phase circuits requiring 20 A protection with C-characteristic behaviour. Confirm that the rated current and trip characteristic match the protected load and coordination scheme of the distribution board. Regularly inspect terminals for tightness and signs of overheating and replace the breaker if mechanical damage or persistent tripping occurs.
