Molded case circuit breaker QOLTEC 52582 — 1000V input, 30A max

Molded case circuit breaker QOLTEC 52582 is designed for electrical protection in installations requiring a maximum input voltage of 1000 V and continuous current handling up to 30 A. The compact molded-case design provides a robust enclosure for thermal-magnetic trip elements that detect overloads and short-circuits, enabling reliable disconnection of circuits in distribution panels, switchboards, and industrial equipment. The breaker integrates with common DIN-rail or panel mounting arrangements and is intended for use where clear, repeatable trip performance and secure mechanical mounting are required.

Advantages

The device offers combined thermal and magnetic protection in a single molded housing, delivering fast response to short-circuit conditions and stable overload protection. Its compact dimensions and standard mounting features simplify installation and replacement in existing panels. The sealed enclosure protects internal trip mechanisms from dust and typical workshop contaminants, contributing to long-term operational reliability. The product is compatible with typical control and distribution systems used in light industrial and commercial electrical installations.

Suitable for

• Protection of distribution circuits in commercial and light industrial electrical panels
• Overcurrent and short-circuit protection for equipment fed at up to 1000 V
• Use in switchboards and control cabinets with limited space
• Replacement of existing molded-case breakers with similar form factor

Key specifications

• Maximum input voltage: 1000 V
• Maximum continuous current: 30 A
• Protection type: thermal-magnetic (overload and short-circuit)
• Enclosure: molded-case housing for mechanical protection
• Mounting: panel or DIN-rail compatible installation

How to use

Install the molded case circuit breaker in the distribution panel according to local electrical regulations and the panel manufacturer's instructions. Ensure power is isolated before wiring. Connect line and load conductors to the designated terminals, verify tightening torques for terminals, and confirm correct polarity and phase connections. After installation, perform an insulation and continuity check on the circuit and test the breaker operation under controlled conditions to confirm correct trip response.

Usage recommendations

Choose appropriate conductor sizes and tightening torque values to match the 30 A rating and the installation standards in your region. Periodically inspect terminals for tightness and signs of overheating, and test trip functionality during scheduled maintenance to ensure ongoing protection performance.
