SL2 / SLH2 – Slimline Surge Protector

Description

The Novaris SL2 and SLH2 range provides 20kA high energy surge protection for balanced pair signaling circuits, used in a wide range of industrial monitoring and control equipment. 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 Protectors

Description

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.

Product Codes: SSP6A-14-G, SSP6A-26-G, SSP6A-38-G, SSP6A-65-G, SSP6A-130-G, SSP6A-14-EC90, SSP6A-26-EC90, SSP6A-38-EC90, SSP6A-65–EC90, SSP6A-130-EC90

SSP10A – Series Surge Protector 10A

Description

The Novaris SSP10A is a surge protection device designed to protect AC and SC low voltage power supplies. The SSP10A has zero earth leakage current and will prevent the tripping of supply fuses down to 2A should a transient overvoltage occur.

The SSP10A series utilises a fused earth connection to provide a failsafe design. The fuse status is monitored via a visual indicator and external alarm contacts. Should the device need replacing, the protection components are contained in a replaceable cartridge.

Product Codes: SSP10A-38, SSP10A-65

SLT – Threaded Signal Line Protectors

Description

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.

Product Codes: SLT1-7v5, SLT1-18, SLT1-36, SLT1-68, SLT1-200, SLT3-7v5, SLT3-18, SLT3-36, SLT3-68, SLT3-200, SLT4-7v5, SLT4-18, SLT4-36, SLT4-68, SLT4-200, SLT4-36-275

SLT-Y – Y Adapter for SLTx

Description

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.

Product Codes: SLT-Y-M20, SLT-Y-N12

SLD – High Surge Current Signal Line Protector

Description

SLD Signal Line Protectors are designed to protect the most sensitive electronic equipment in lightning intense environments. So they are ideal for the protection of PLC’s, fire and security systems, railway signalling and SCADA equipment.

Models feature multistage transient protection which delivers a greater level of protection through a staged approach. The primary stage absorbs the majority of the surge energy. The remaining stages provide accurate clamping and a degree of redundancy.

Product Codes: SLD1-7v5, SLD1-18, SLD1-36, SLD1-68, SLD1-485, SLD1-DH, SLD1-PSTN, SLD2-7v5, SLD2-18, SLD2-36, SLD2-68, SLD2-485, SLD2-DH, SLD2-PSTN, SLD4-7v5, SLD4-18, SLD4-36, SLD4-68, SLD4-485, SLD4-DH, SLD4-PSTN
