Product Overview
Type B RCCB in the 16A to 100A range for detecting AC, pulsating DC, and smooth DC leakage in main distribution board positions where overcurrent protection is handled separately by downstream MCBs or MCCBs. The higher current range suits commercial and industrial distribution boards where a single Type B main RCCB protects multiple downstream circuits.
Specifying Type B at the main RCCB position covers the entire downstream circuit for all leakage types, regardless of the mix of load types on the board — simpler than specifying Type B on individual circuit breakers.
100A Type B RCBO covers large single-phase inverter outputs or grouped small-inverter circuits where aggregate current approaches 100A. The B-type detection characteristic adds protection against smooth DC residual currents — verify whether your inverter specifies Type B RCD in its installation manual before substituting a standard Type AC device.
Applications
Inverter output protection
AC distribution boards
EV and PV support circuits
Residential and commercial electrical BOS
Frequently Asked Questions
Why choose a Type B RCCB without overcurrent protection?
Separating residual current and overcurrent functions is standard practice in industrial distribution where different engineers govern each protection function. The RCCB is sized for the board incoming current; downstream MCCBs or MCBs handle individual circuit overcurrent protection.
What is the residual current sensitivity?
Available sensitivity ratings for high-current RCCBs include 30mA, 100mA, and 300mA. Specify the required sensitivity at RFQ — 300mA is common for fire protection in main distribution, 30mA for personal protection circuits.
