Procurement & BOM Notes
How EKL5-63B Type B RCBO—Professional Residual Current Circuit Breaker for AC, Pulsating DC, and Smooth DC Leakage Protection is sourced
OmniSol sources EKL5-63B Type B RCBO—Professional Residual Current Circuit Breaker for AC, Pulsating DC, and Smooth DC Leakage Protection factory-direct as part of the RCBO family, quoted against your project quantity, destination port and product family id (OS-ETK-EKL5-63B). Pricing and lead time are confirmed by SKU and order size at the RFQ stage, and OmniSol can propose a current-equivalent option if the exact variant is unavailable, so the line stays on schedule.
BOM fit
EKL5-63B Type B RCBO—Professional Residual Current Circuit Breaker for AC, Pulsating DC, and Smooth DC Leakage Protection sits between the array and the inverter, so it is specified with the string count, system voltage and protection layout of the project. It ships consolidated with cable, connectors and the rest of the electrical BOS, under one QC report and one document set.
Certification check
Confirm the device standard, breaking capacity and any market-specific listing (IEC or UL) before ordering. OmniSol supplies the datasheet, component brand list and inspection photos.
Product Overview
Eighteen variants covering 6A to 63A in both single-phase (1P+N) and three-phase (3P+N) configurations make this the most comprehensive Type B RCBO in the range. Three-phase Type B RCBOs are relevant in commercial and industrial installations with three-phase VFD, power electronics, or three-phase EV charging equipment.
Type B sensitivity to smooth DC leakage closes the protection gap that standard Type AC and Type A devices leave open when protecting circuits served by transformerless power conversion equipment.
63A Type B RCBO sizing covers single-phase string inverters in the 10–15kW range. Type B detection is required where the inverter topology can produce a smooth DC fault component — check the inverter installation manual for the RCD type specification, as the wrong type will not detect all fault modes.
Applications
Inverter output protection
AC distribution boards
EV and PV support circuits
Residential and commercial electrical BOS
Frequently Asked Questions
When do I need a 3P+N Type B RCBO?
Three-phase Type B is needed for three-phase loads generating DC leakage — three-phase EV chargers, variable-frequency drives, three-phase transformerless inverters. Single-phase Type B covers single-phase power electronics loads. Specify the load type and we recommend the correct pole configuration.
Is Type B RCBO required in all markets for EV charging?
The EU requires Type B or equivalent protection for EV charging outlets (EN 61851 and related standards). Requirements vary by country and installation type — a Type B device is accepted everywhere that Type A is required, so it is the safe default choice.
