LS Electric Earth Leakage Circuit Breaker (ELCB/RCCB)

The LS Electric Earth Leakage Circuit Breaker (ELCB) — also known as a residual current circuit breaker (RCCB) — is a protective device designed to disconnect an electrical circuit when it detects a difference between line and neutral currents that indicates current leaking to earth, protecting personnel from electric shock and electrical installations from earth fault fire risk. The LS Electric ELCB range covers 2-pole and 4-pole configurations from 25 A to 125 A with trip sensitivities of 10 mA, 30 mA, 100 mA, 300 mA, and 500 mA, covering the full spectrum of earth leakage protection requirements from personal protection (30 mA) to equipment protection (300 mA) and fire protection (100 mA) as defined in IEC 61008 and the Saudi Electrical Code requirements for residual current protection.

The LS Electric ELCB features a test button for periodic verification of operation, a trip indicator flag for clear fault identification, and an electromechanical operation mechanism that operates within 30 ms at 1x trip current (meeting the IEC 61008 disconnection time requirement for personal protection). The 4-pole version is essential in TN-S earthing systems and three-phase installations where neutral current imbalance from single-phase loads must be included in the residual current measurement. The ELCB range is compatible with LS Electric MCBs and MCCBs for combination in residual current circuit breakers with overcurrent protection (RCBO) assemblies, giving panel builders flexibility in protection device selection and DIN rail space optimisation.

In Saudi Arabia, earth leakage protection is mandatory under the Saudi Electrical Code in all new residential, commercial, and industrial electrical installations, and is required for socket outlet circuits, bathroom circuits, outdoor circuits, and equipotential bonding systems per IEC 60364 as adopted in the Kingdom. The LS Electric ELCB meets all Saudi Electrical Code and IEC 61008 requirements at a SAR price significantly below European branded RCCBs such as ABB F200 and Siemens 5SV, making it the cost-effective compliance solution for Saudi builders, contractors, and facility managers responsible for electrical safety in residential and commercial developments.

Razz Middle East stocks the ELCB in all standard current ratings and trip sensitivities for immediate Saudi Arabia supply. Our team provides guidance on ELCB selection for compliance with Saudi Electrical Code earth leakage protection requirements and IEC 60364 zone protection coordination.
