DZ1540 3P 40A Circuit Breaker Air Switch for Motor Protection 380V Reliable Overload Safety

Product: DZ15 plastic shell type circuit breaker Overview The DZ15 plastic shell type circuit breaker is designed for protection and switching in AC electrical systems. It is suitable for use on 50 Hz supply networks with a rated voltage of 380 V and rated currents up to 100 A. The device provides reliable power distribution protection, motor overload and short circuit protection, and can be used for infrequent line switching and motor starting. Key benefits Reliable protection: Detects and interrupts overloads and short circuits to protect wiring and equipment from damage. Multifunctional use: Acts both as a distribution breaker and as motor protection and switching device for infrequent starts. Clear electrical ratings: Designed specifically for AC 50 Hz, rated voltage 380 V, rated current up to 100 A for predictable compatibility with common systems. Durable housing: Plastic shell construction provides insulation and physical protection for internal components. Simplified system integration: Suitable for power distribution panels and motor circuits where infrequent switching or starting is required. Features and attributes Function: Overload protection, short circuit protection, power distribution switching, infrequent line conversion, and motor infrequent start. Compatibility: Intended for AC systems at 50 Hz and 380 V nominal voltage. Rated current options available up to 100 A to match circuit requirements. Material: Plastic shell type housing for electrical insulation and protection. Performance: Designed to interrupt fault currents and limit thermal and electrical stress on wiring and connected equipment when used within rated conditions. Models and identification: Product identified by model code DZ15 and its specified electrical ratings. Practical applications 1. Motor control panels: Protect and switch motors in light to medium duty applications where starts are infrequent and overload and short circuit protection are required. 2. Distribution boards: Use in residential or commercial distribution panels for branch circuit protection on 380 V AC systems up to 100 A. 3. Workshop and light industrial equipment: Provide primary circuit protection for machines and equipment that need reliable overload and short circuit protection and occasional manual switching. Installation and selection tips Match the rated current to the circuit load without exceeding 100 A. Confirm the supply frequency is 50 Hz and the system nominal voltage is 380 V before installation. Use the breaker for infrequent switching or motor starts as intended; for frequent switching or specific motor protection needs consult system requirements. Ensure wiring and downstream devices are rated to the same electrical levels as the breaker. What this product solves Prevents equipment damage from overloads and short circuits by interrupting fault conditions. Consolidates power distribution and basic motor protection into a single device for simpler panel layouts. Provides a reliable switching option for circuits that do not require frequent operation or advanced motor control.
