Quick Summary
The SV ISV terminal block is a high-current connection solution designed for enclosure-based power distribution in control panels and switchgear. In practical settings, engineers often struggle with secure, space-efficient conductor termination and safe access for maintenance. The device supports a 5-pole layout with a 250 A maximum current at 690 V, accommodating round conductors 16–150 mm² and laminated copper bars up to 17x21 mm, all housed in a durable Duroplastic body (RAL 7035). While explicit certifications aren’t listed here, this design aligns with standard industrial enclosure practices to help reduce installation risk and streamline panel builds. Use this block to improve reliability, ease of assembly, and overall system throughput in your electrical infrastructure projects.

FAQs
Begin by ensuring the enclosure provides adequate space for a 5-pole block and that conductor sizes fall within 16 to 150 mm² for round conductors. Use the included assembly parts and align the block with the mounting pattern. Remember that a hazard protection module 9666.020 is required to cover the connection terminals for safe operation.
The SV ISV supports round conductors from 16 to 150 mm² and can also accommodate laminated copper bars up to 17x21 mm. It is suitable for copper and aluminium conductors, as well as laminated copper bars, enabling versatile wiring within a single terminal block.
Yes. With a rated current of up to 250 A and a voltage rating of up to 690 V, this block supports demanding, high-current panel applications such as power distribution, control cabinets, and switchgear. Its 5-pole configuration allows organized multi-phase terminations in compact layouts.
The provided data does not list specific certifications (such as CE, SIL, or IP ratings). For confirmation on current accreditation, consult Rittal or the supplier documentation. The product design aligns with typical industry safety and enclosure standards, but please verify certifications for your project requirements.
The 9666340 SV ISV Terminal Block offers durable Duroplastic housing and straightforward round/conductor and lamination connections, which reduces installation time and torque variability.
