ABB Insulation Monitoring Relay 3 Phase 1 Phase SPDT Screw Terminals DIN Rail Mount 240 V AC/DC 1SVR730660R0100 CM-IWS.1S

ABB 1SVR730660R0100 CM-IWS.1S insulation monitoring relay is designed for robust monitoring of insulation resistance in both 3 phase and single phase electrical circuits. With SPDT contact configuration, this device ensures reliable detection of insulation faults to prevent electrical hazards and machinery damage. Its compact DIN rail mounting facilitates easy installation in control panels.

The relay operates at supply voltages of up to 240 V AC and 240 V DC, capable of sensing maximum voltages of 250 V AC and 300 V DC. It integrates screw terminal types for secure and stable electrical connections. The unit’s compact dimensions (103.7 mm length, 22.5 mm width, and 85.6 mm height) enable use in confined panel spaces, maintaining efficient space management.

Featuring three LED indicators, the relay provides immediate visual feedback on its operational status, aiding maintenance and monitoring activities. The device allows precise adjustment of threshold values in 1 kΩ increments within a 1-100 kΩ measuring range to meet specific circuit requirements. Additionally, it includes interrupted wire detection enhancing operational safety by identifying wiring faults.

This ABB relay is suited for demanding environments such as construction sites, solar power systems, marine applications, and IT infrastructures. It meets industry compliance through standards including UL, RoHS, and CSA, guaranteeing adherence to global quality and safety norms.

Weighing just 0.148 kilograms, this lightweight relay minimizes strain on mounting equipment without compromising durability or function. It supports critical protective functions where standard circuit breakers and residual current devices may not respond effectively due to insufficient earth fault detection energy.
