Select the overload setting to suit the motor nameplate current and coordinate the device with the contactor and upstream short-circuit protection.
Applications
- Direct-on-line motor starter assemblies
- Three-phase induction motor protection
- Commercial HVAC and refrigeration plant
- Pumps, fans and compressors
- Industrial machinery and production equipment
- Motor control panels and switchboards
Standards & Compliance
- Manufacturer documentation references IEC/EN 60947-2 for circuit-breaker functions and IEC/EN 60947-4-1 for motor-starter applications; verify the applicable AS/NZS adoption and local approval requirements before installation.
- Electrical installation and switchboard integration should be completed in accordance with AS/NZS 3000 where applicable.
Environmental Benefits
- Thermal and magnetic protection can help prevent motor damage and reduce premature equipment replacement.
- Durable reusable switchgear construction can reduce waste compared with replacing complete motor-control assemblies.
- Supports correct motor protection and operation, helping avoid energy losses associated with overloaded or damaged motors.
