Product Features of the Type B RCBO
Constructed for demanding commercial environments, this Type B RCBO integrates a highly responsive electronic ground fault trip mechanism alongside reliable thermo-magnetic short-circuit defense.
- Comprehensive Leakage Detection: Detects residual AC, pulsating DC, and smooth DC currents up to 1kHz, offering absolute protection against complex multi-frequency faults.
- Compact Single-Module Design: Maximizes DIN rail space efficiency (1P+N) without sacrificing high-end protective capabilities, supporting rated currents up to 40A.
- Bidirectional Power Capability: Fully supports bidirectional incoming power routing, crucial for solar photovoltaic panel configurations and energy storage networks.
- Touch-Safe Architecture: Features IP20 finger-protected terminals, securing live parts from hazardous operator contact during routine electrical maintenance.
- Immediate Status Verification: Integrates a prominent red/green mechanical indicating device on the faceplate for instantaneous switching status recognition.
