Applications include SCADA, PLC, fire and security systems, telecommunications and railway signaling. The SL2 is designed for protecting communication circuits with a 3dB of 60Mhz and the SLH2 is designed for instrumentation power circuits requiring up to 2.5A of current.. The SL2 and SLH2 range integrates a fault indicator and external alarm connection for surge protection monitoring. They are available with a -EC90 option to isolate the earth connection for protection of field equipment. The protection and alarm circuit is contained in a replaceable cartridge to minimise downtime.

SSP6A

Slimline Series Surge Protector SSP6A

The SSP6A series surge protectors complement the SL range for applications of load currents up to 6A. Typical applications may include power supplies, instrumentation and other low voltage requirements up to 6A. With two different base options the SSP6A protectors offer either direct earthing via DIN rail, for the most effective, low impedance earth connection (-G base) or a connection via GDT to the DIN rail, offering isolation under normal conditions and equipotential bonding during a surge (-EC90 base). The plug-in design provides simple and rapid replacement and testing – no rewiring needed. This also provides a convenient method of field equipment isolation if required.

SLT31

Threaded Signal Line Protectors SLT

Novaris threaded instrument protectors provide surge protection for instrumentation and are designed to be installed directly at the field equipment providing protection against induced surges and transients. They are suitable for two, three and four wire instruments. SLT models are available for signalling systems up to 200V. The multistage design provides a high energy gas discharge tube (GDT) as primary protection for common mode disturbances, commonly associated with lightning strikes and power system earth faults and a secondary metal-oxide varistor clamping stage across the signal lines. This combination provides very robust surge protection with high transient suppression and low let-through voltages. In addition protection is provided for cable screens which may be open circuit at the instrument.

P1V1

Y Adapter for SLT

The SLT-Y offers a solution when a field instrument has no free cable entry to accommodate the SLT threaded instrument protector. The Novaris Y-piece adapter accommodates the SLT threaded instrument protector and cable gland. The SLT-Y is available in the same thread types as the threaded instrument protectors. The IS-SLT-Y-M20 is an IEC Ex and ATEX EX d certified version of the Y-Adapter, and so may be installed in Ex d rated instruments without loss of integrity.
