FAQs
ES3T4R1B is designed for straightforward DIN-rail mounting in standard control panels. It uses plug-in terminals for quick electrical connections and compatible bus communication or signaling schemes found in typical industrial automation setups. When replacing older devices, verify torque values and conductor size to ensure reliable clamping, and confirm the device fits within the panel’s enclosure rating for safe operation.
The device delivers thermal-magnetic overcurrent protection, providing both overload and short-circuit protection for feeders and motor circuits. This enables selective tripping and fast fault isolation, reducing motor damage risk and downtime. It is suitable for integration in motor control centers and automated lines where protection coordination with upstream devices is required.
ES3T4R1B is designed for general electrical protection with CE compliance and standard safety practices. A SIL-rated implementation depends on specific configurations and accompanying safety architecture. For SIL-related applications, refer to the product’s variant documentation and perform a formal risk assessment to determine suitability and any required redundancies or integration with safety-rated components.
ES3T4R1B is positioned for CE compliance as a baseline certification, with alignment to IEC 60947-2 for low-voltage circuit protection devices. When selecting this model for regulated environments, confirm the IEC/UL listings applicable to your region and application, and ensure compatibility with your plant’s internal standards and audit requirements.
Deploying ES3T4R1B can lower total cost of ownership through reduced downtime from reliable protection and faster fault isolation. Its DIN-rail compatibility simplifies replacement, minimizes panel modification, and enables standardized maintenance procedures across multiple lines. The result is shorter mean time to repair (MTTR), fewer spare parts, and improved uptime in automation facilities.
