Class B - Low Voltage Power System Protection
The Class B series of over-voltage surge protective devices has been developed to protect against partial direct and indirect lightning discharges and is intended to provide protection in zones 0A - 1, per IEC 62305.
Category IEC / EN / VDE: Class I, II / Type 1, 2 / B + C. This range incorporates remote signalling contacts for central monitoring of SPD health.
DVSB275652TNS for TNS single phase networks with separate N and PE conductors.
DVSB400654TNS (65kA) for TNS three phase networks with separate N and PE conductors.
DVSB4001004TNS (100kA) for TNS three phase networks with separate N and PE conductors.
DVSB4001004TT for TT three phase networks, where N to PE galvanic isolation is required.
