Overview

Specifications

Key Features

• Compact Structure: Adopts 1P single-pole design, perfectly suitable for control cabinets with limited installation space, helping to save cabinet layout space.
• Fast Response: Equipped with magnetic tripping mechanism, which can quickly disconnect the circuit in case of overload or undervoltage, effectively protecting downstream electrical equipment from damage.
• High Reliability: Complies with IEC 60947-2 standard, with strong anti-interference performance and excellent mechanical durability, ensuring stable operation for 30 Mcycles.
• Protection Level: IP40 protection level (in accordance with IEC 60529 standard), applicable to general industrial environments, effectively preventing dust intrusion.

Structure & Components

• Coil Assembly: When the current exceeds the set threshold, the coil generates magnetic force to drive the tripping mechanism, triggering the circuit disconnection action.
• Tripping Mechanism: Composed of spring and electromagnet, it is responsible for quickly opening the contacts when overload occurs, realizing rapid circuit breaking.
• Contact System: Includes normally closed (NC) contacts, which disconnect the circuit after tripping; it may also be equipped with normally open (NO) contacts for signal indication, facilitating staff to monitor the working status.
• Terminals: Used for connecting power cables, load cables and control signal lines, with reasonable design to ensure convenient and firm wiring.

• Industrial Automation: Used as a signal output or protection component in PLC control cabinets, matching with automatic control systems to improve the stability of the whole system.
• Machine Tools & Equipment: Provide reliable electrical protection for various mechanical equipment, reducing equipment failure caused by electrical faults.
• Shipbuilding & Rail Transit: Suitable for electrical control systems in marine, railway and other fields, adapting to harsh working environments.

Installation & Maintenance

• Installation: With 1P single-pole design, it is usually installed on the DIN rail in the control cabinet, and the backplate is used as the installation support to ensure stable installation.
• Wiring: Equipped with front terminals, it is necessary to ensure firm wiring during installation to avoid poor contact caused by loose wiring, which affects the normal operation of the product.
• Maintenance: Although the product does not require an additional protective enclosure (Without protection), in dusty or corrosive environments, it is recommended to regularly check the cleanliness of terminals and contacts to ensure good electrical conductivity and extend the service life of the product.
