It operates effectively within a temperature range of -20 °C to +60 °C and offers a high current rating suitable for motor protection.
Features & Benefits
• Supports FLC motor ratings between 2.5A and 4A
• Features automatic and manual reset mechanisms
• Designed with a robust 3P configuration for enhanced reliability
• Offers a contact voltage rating of up to 690V AC
• Equipped with screw terminals for secure connections
• Complies with thermal overload class 10A for effective motor safeguarding
Applications
• Used for motor protection in diverse AC and DC networks
• Compatible with various contactor models for flexibility
• Ideal for electrical panels requiring efficient thermal relay solutions
• Employed in industrial automation processes to prevent motor damage
How does the tripping mechanism work during motor overload situations?
The tripping mechanism is designed to activate once the current exceeds 130% of the rated current on two phases, ensuring immediate protection of the motor from potential damage.
What type of connections are supported for control circuits?
The relay supports screw clamp terminals for control circuits, accommodating flexible cables of 1 to 2.5mm² without cable ends for easy installation and maintenance.
What are the implications of its IP20 rating?
An IP20 rating indicates that the device is protected against solid objects exceeding 12mm but does not offer protection against water, making it suitable for dry indoor environments.
How can temperature variations affect the performance of this relay?
The relay operates reliably between -20 °C and +60 °C, ensuring proper function across typical operational conditions without derating.
What is the benefit of using multiple auxiliary contacts?
Having two auxiliary contacts allows for enhanced circuit control, providing additional functionalities such as signalling and integration into larger control systems.
