Molded case circuit breaker Qoltec 52583 1000 V 20 A

The Qoltec 52583 molded case circuit breaker is designed for protection of electrical circuits with an input voltage of 1000 V and a rated current of 20 A. This compact protective device interrupts overloads and short circuits to reduce the risk of damage to equipment and wiring. Constructed with a molded insulating housing, it is intended for reliable operation in industrial and commercial electrical installations where a 1000 V supply is present.

Advantages

The molded insulating body reduces the risk of tracking and ensures stable dielectric performance under normal operating conditions. The device provides precise overcurrent interruption at the specified 20 A rating and is built to deliver consistent performance in repeated switching events. Its form factor facilitates straightforward panel or DIN-rail mounting and integration into control cabinets and distribution boards. Designed to be maintenance-light, it offers a balance of electrical protection and operational simplicity.

Suitable for

• Overcurrent protection in 1000 V DC or AC electrical circuits requiring up to 20 A
• Industrial machinery control panels and distribution boards
• Photovoltaic arrays and renewable energy systems with high-voltage sections
• Commercial electrical installations and equipment cabinets

Key specifications

• Rated voltage: 1000 V
• Rated current: 20 A
• Molded insulating housing for enhanced dielectric strength
• Overcurrent and short-circuit interruption capability at specified rating
• Compact footprint suitable for panel or cabinet mounting

How to use

Install the circuit breaker in accordance with local electrical codes and the system design. Ensure supply voltage and circuit current requirements match the device ratings before connection. Mount the unit securely in the distribution board or control panel and make tight, clean terminal connections using appropriate tooling. After installation, verify correct operation by performing recommended commissioning tests and confirm the breaker trips under simulated overcurrent conditions. Periodically inspect terminals and housing for signs of wear, overheating, or contamination.

Usage recommendations

Use the breaker within its rated voltage and current limits and avoid exposing it to conditions outside its intended environment such as excessive humidity, corrosive atmospheres, or temperatures beyond manufacturer guidelines. Coordinate protection settings and select upstream or downstream devices as needed to ensure proper selectivity in multi-device systems.
