Surge Protection Devices (SPDs)

Roxburgh's SPDs are suitable for signal line protection, DC power supply and low voltage power distribution

This range of Surge protectors reduce the transient overvoltages inside a facility or equipment, protecting against the indirect effects of lightning, and transients which originated within the facility.

All cables leaving a building can also provide a route back into the building, therefore, protection must be installed on: Mains Power Supplies (including UPS Class C and Class B); Data Communications and Local Area Network Cables; Signal, Control, Instrumentation and Alarm Lines; Telephone and Telemetry Lines.

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.
