Feature → Business Impact → Application: 3P E-LSIG shunt release for Tmax T delivers reliable signaling by providing a direct, low-impedance path to the breaker’s tripping coil. This translates into faster, more predictable trips and reduced field wiring errors, especially in crowded control cabinets or harsh environments. Use it with Tmax T 3P protection schemes at 250 A to enable configurable, loose mounting while preserving clear diagnostic signals. Compliance assurance: REACH Declaration, RoHS Information, and RoHS Status confirm environmental compliance. Business impact: Simplifies cross-border procurement and reduces regulatory review time. Application: Suitable for global projects needing CE declarations and TSCA conformance. Compatibility and flexibility: Loose or configurable installation supports variations in panel depth and mounting patterns. Business impact: Helps reduce field rework and enables future upgrades without replacing the whole assembly. Application: Ideal for retrofits and new Tmax T installations in industrial plants. Performance and handling: 1 kg net weight aids ease of handling in installation workflows. Business impact: Improves on-site logistics and reduces labor time. Application: Mounting with standard Tmax T enclosures and accessories. Documentation and traceability: Data Sheet 1SDC210285M0201, Declaration of Conformity 1SDL000165R0004, Manuals 1SDC210033D0202. Business impact: Accelerates QA checks and audit readiness. Application: Essential for quality control in plant operations.

FAQs
Begin with the system de-energized and verify mounting space for a loose or configurable 3P release. Connect the shunt release to the breaker’s tripping circuit following the data sheet instructions, torque connectors to spec, and secure the unit in the allotted Tmax T mounting pattern. Verify wiring integrity and test the trip function per the manual (1SDC210033D0202) before commissioning.
Yes. The 1SDA081079R1 is designed as an accessory for Tmax T 3P protection schemes up to 250 A, with loose or configurable mounting. It integrates with typical control wiring in industrial cabinets and supports straightforward retrofits or new installations, reducing wiring complexity and enabling consistent signaling across assemblies.
The accessory includes REACH Declaration, RoHS Information and RoHS Status, TSCA declaration, and CE conformity. Documentation aligns with IEC standards and ETIM classification, ensuring global compliance and streamlined approval workflows for multinational projects.
The 1SDA081079R1 provides reliable EL release signaling, reducing mis-trips and field wiring errors. This shortens commissioning time, lowers maintenance interventions, and improves overall uptime in critical power distribution environments, especially where Tmax T protection is pivotal to process continuity.
Key technical resources include the Data Sheet 1SDC210285M0201, Declaration of Conformity 1SDL000165R0004, and the Instructions and Manuals 1SDC210033D0202.
